技术领域 Technical Field

[0003] 本发明涉及一种用于组合进光学成像系统内的透镜元件,并且特别涉及到一种包括可变形透镜元件的装置和方法。 [0003] The present invention relates to a composition into a lens element within the optical imaging system, and more particularly to apparatus and method for a lens element comprising a deformable.

背景技术 Background

[0004] 例如多焦距透镜和变焦透镜的可变透镜传统上应用了一个或多个不可变形的(也就是,如玻璃和聚碳酸酯一样刚性的)透镜元件,其被一般由马达提供的力沿着成像轴移动。 [0004] The conventional multi-lens such as a variable focus lens and the zoom lens on the application of one or more non-deformable (i.e., rigid such as glass and polycarbonate) is a lens element, which is generally provided by a motor force move along the imaging axis.

[0005] 在最近几年中,无马达电场响应透镜元件已经引起光学系统研究者和设计者日益增长的关注。 [0005] In recent years, no motor response to an electric field of the optical system of the lens element has attracted researchers and designers of the growing concern. 一种无马达电场响应透镜元件的类型是“流体透镜”透镜元件,其一般包括填满一种或多种具有折射率大于1的流体的刚性或弹性薄膜。 Motor in response to a non-electric field type lens element is "fluid lens" lens element, which generally includes one or more fill fluid having a refractive index greater than 1 in the rigid or elastic film. 流体透镜元件技术已经引起许多光学系统的设计者的关注,他们一般认为传统固体透镜元件和马达装配的系统是笨重的并且消耗能量的。 Fluid lens element technology has attracted the attention of many optical systems designer, who is generally believed that the traditional solid lens element and motor assembly system is cumbersome and consumes energy. 随着对流体透镜元件的提议,已经建议各种方法来改变用于组合进光学系统内的流体透镜元件的光学性质。 With the proposal of the fluid lens element, various methods have been proposed for modifying the optical properties combined into a fluid lens element within an optical system. 无论在哪里建议了流体透镜元件,可以将用于改变该透镜元件的光学特性的被建议选择项归类为两个主要种类:电湿润和流体注入。 Wherever recommended fluid lens element, can be used to alter the optical characteristics of the lens elements is recommended to choose the items are classified into two major types: an electro-wetting and fluid injection.

[0006] 根据电湿润的处理过程,提供具有至少两种不溶合的流体的流体透镜元件,并且将电压施加到该流体透镜元件上。 [0006] According to the electro-wetting process, providing a fluid lens element having at least two non-fusion of the fluid, and a voltage is applied to the fluid lens element. 作为施加电压的结果,该流体透镜元件的表面张力发生改变,引起在该至少两种流体之间的界面曲率发生改变。 As a result of the applied voltage, the surface tension of the fluid lens element changes, causing the curvature of the interface between the at least two fluids are changed.

[0007] 根据流体注入的处理过程,提供邻近流体透镜元件的泵,其从该透镜元件内泵进和抽出流体。 [0007] According to the process fluid injection, there is provided a fluid pump adjacent lens elements, which pumps fluid into and withdrawn from the lens element. 随着将流体泵进和抽出该透镜元件,该透镜元件的光学特性发生改变。 With the fluid pump inlet and extraction of the lens element, the optical characteristics of the lens element changes.

[0008] 关于用来改变流体透镜元件的光学特性的所述电湿润和流体注入方法的问题都已经被注意到。 [0008] The electro-wetting and flow on to alter the optical characteristics of the fluid lens element implantation of problems have been noticed. 关于电湿润,已经被注意到的一个问题是随着时间的过去,电流重复地流过该透镜元件易于改变该透镜元件的特性,致使在其中使用了该透镜元件的任何系统是不可靠和不稳定的。 On electro-wetting, it has been noticed a problem is over time, the current flowing through the lens repeatedly element characteristics of the lens element can be easily changed, resulting in the use of any system in which the lens element is not reliable and not stable. 关于涉及电湿润的建议被注意的另外一个问题是,电湿润常规地涉及提供两种流体。 Moist recommendations for involving electrical unnoticed Another problem is that conventional electro-wetting to providing both fluids. 当这两种流体之间的参考系数差别小的时候,该透镜的倍率被降低。 When the reference coefficient difference between the two fluids is small, the magnification of the lens is reduced.

[0009] 关于所述流体注入方法,用来提供这种流体注入的所述泵是必不可少的。 [0009] For the fluid injection method, for providing such a fluid injection pump is essential. 其复杂难懂使得制造成本合适的系统和可接受的小型化难以获得。 Its intricacies so that the manufacturing cost of suitable and acceptable system miniaturization difficult to obtain.

[0010] 由于被注意到的关于用来改变可变形透镜元件的光学特性的所述电湿润和流体注入方法二者的问题,商业上的设计者在光学系统的设计中几乎全部继续依靠传统马达驱动刚性透镜元件来配置光学系统。 [0010] Due to be noticed and the electro-wetting fluid injection method is used to change both on the optical properties of a deformable lens element problem, the designer business continue to rely almost entirely on the design of the optical system in the conventional motor driving the rigid lens elements of the optical system is configured. 然而,用装配在光学系统中的马达驱动刚性透镜元件可达到的最小化和节能仍然是有限的。 However, with the assembly of the motor drive in the optical system of rigid lens element can achieve minimization and energy is still limited.

[0011] 简而言之,流体透镜,有时候也被称为适应性透镜,包括在具有不同光学折射率的两种流体之间的界面。 [0011] In short, the fluid lens, sometimes referred to as adaptive lens, comprised between two fluids having different optical index of the interface. 通过使用外力可以改变该界面的形状,以便穿过该界面的光线能够被引导到以期望的方向加以传播。 By using an external force can change the shape of the interface, so that the light passing through the interface can be directed to a desired direction to spread. 因此,,流体透镜的光学特性,例如该透镜是用作发散透镜或用作会聚透镜,以及它的焦距,能够响应于该施加的外力而被改变。 Therefore ,, the optical characteristics of the fluid lens, e.g., the lens is used as a converging lens or a diverging lens, and its focal length, in response to the applied external force is changed.

[0012] 使用电信号控制该流体透镜操作的流体透镜技术已经被名称不一地描述在Matz 的US专利第2062468号;Berge等人的US专利第6369卯4号;Onuki等人的US专利第6449081号;Tsuboi等人的US专利第67(^483号;Onuki等人的US专利第6806988 号;Nagaoka等人的US专利申请第2004/0218283号;Takeyama等人的US专利专利申请第2004/0228003号;Berge的US专利申请第2005/0002113号和国际专利申请第WO 99/18546、WO 00/58763、和W003/069380 号中。 [0012] The use of an electrical signal to control the operation of the fluid lens fluid lens technology has been described in various names Matz of US Patent No. 2062468; Berge et al., US Patent No. 6369 d 4; Onuki et al., US Patent No. Tsuboi et al., US Patent No. 67 (^ 483;; Number 6449081 Onuki et al., US Patent No. 6806988; US Patent Application No. 2004/0218283 Nagaoka et al; Takeyama et al.

[0016] 然而,在目前的系统中,对改进使用流体透镜的系统和方法有持续的需求。 [0016] However, in the current system, there is a continuing need for improved systems and methods using a fluid lens.

[0017] 透镜和透镜系统可以是固定的或可变化的,并且透镜系统可以包括固定的和/或可变化的透镜。 [0017] The lens and the lens system can be fixed or variable, and the lens system may include fixed and / or variable lens. 固定的透镜系统和固定的透镜具有固定的和静止焦点,也就是说,焦距和光轴的方向不发生变化。 Fixing the lens system and the fixed lens having a fixed focus and a stationary, i.e., the direction of the optical axis and the focal length does not change. 例如,刚性地连接到光学系统的不可变形固体透镜将被自然而然地固定。 For example, the optical system is rigidly connected to the non-deformable solid lens will be naturally secured. 并且如果该透镜不包括任何其他能够改变该透镜系统焦距和/或该透镜系统的光轴方向的元件,该透镜系统将同样是固定的。 And if the lens does not include any other system capable of changing the focal length of the lens and / or the elements of the optical axis of the lens system, the lens system will also be fixed.

[0018] 一副普通眼镜就是这样的固定透镜系统。 [0018] an ordinary glasses is such a fixed lens system. 在眼镜中的每个透镜是固定的透镜,因为它不能够改变它的焦距或它的光轴方向。 Each lens in the glasses lens is fixed, because it is not possible to change the focal length or its optical axis direction. 因为该眼镜不包括实现这种改变的任何附加透镜或其他方法。 Because the glasses do not include any additional lens or implement other methods of this change. 该眼镜本身是固定透镜系统。 The eyeglass lens system itself is fixed.

[0019] 这可以和包括两片玻璃透镜的简易望远镜作一个对比。 [0019] This can include two simple glass lens telescope for a comparison. 每片都被刚性地连接到望远镜外壳不同的同心部分,在那里可以通过滑动该外壳相对于彼此的同心部分来移动该透镜互相接近或互相远离。 Each piece are rigidly connected to the telescope housing different concentric section where you can slide the housing relative to one another to move the lens concentric portion close to each other or away from each other. 每个单独透镜是固定的,它们自然而然地不能改变焦距和光轴的方向。 Each individual lens is fixed, they naturally can not change the focus and the optical axis direction. 然而,该望远镜整体是个可变的透镜系统,因为滑动该外壳相对于彼此的同心部分通过改变这两个固定透镜之间的距离改变了焦距。 However, this is a variable whole telescope lens system, since the sliding housing portion concentrically with respect to each other by changing the distance between the two fixed lens changes the focal length.

[0020] 相比之下,可变形透镜是本质上可变形的,并且任何包含它的透镜系统同样是本质上可变形的。 [0020] In contrast, the deformable lens is essentially deformable, and any material that contains its lens system is also essentially deformable. 固定透镜一般由不可变形材料组成,例如玻璃或塑料;或者,如果固定透镜由弹性的或可变形的材料组成,其是不包括任何用于导致它们延长、压缩、弯曲或其他变化形状或变形的方法的透镜系统的一部分。 Usually the non-deformable fixed lens material, such as glass or plastic; or, if the fixed lens made of an elastic or deformable material composition, which does not include any of them for causing extension, compression, bending or other change in shape or deformed part of the method of the lens system. 可变形透镜可以由弹性的或可变形的材料组成, 并且,在期望透镜在被延长、压缩、弯曲或其他变形之后能够恢复它的初始状态的情况,其由一个或多个弹性可变形元件组成。 The deformable lens may be made of an elastic or deformable material, and the desired lens is extended, compressed, or otherwise deformed after bending can be restored to its initial state of the case, which consists of one or more elastically deformable element consisting of .

[0021] 可以使用一些类型的力元件来提供改变可变形透镜的界面形状所需的力。 [0021] Some types of force may be used to provide elements of a deformable lens to change the shape of the force required to interface. 应用电信号控制流体透镜操作的流体透镜应用技术已经被描述在Matz的US专利第2,062,468 号、Berge等人的US专利第6,369,954号、Onuki等人的US专利第6,449,081号、Tsuboi 等人的US专利第6,702,483号、Onuki等人的US专利第6,806,988号、Nagaoka等人的US 专利申请公开第2004/0218283号、Takeyama等人的US专利申请公开第2004/0228003号、 Berge的专利公开第2005/0002113号、国际专利申请公开第WO 99/18546,WO 00/58763、和W003/069380号以及Havens等人的US专利申请公开第20070063048号中。 Application of an electrical signal to control the operation of the fluid lens fluid lens application techniques have been described in Matz's US Patent No. 2,062,468, Berge et al., US Patent No. 6,369,954, Onuki et al., US Patent No. 6 No. 449,081, Tsuboi et al., US Patent No. 6,702,483, Onuki et al., US Patent No. 6,806,988, Nagaoka et al., US Patent Application Publication No. 2004/0218283, Takeyama, etc. al., US Patent Application Publication No. 2004/0228003, Berge Patent Publication No. 2005/0002113, International Patent Application Publication No. WO 99/18546, WO 00/58763, and No. W003 / 069380 and US Patent Application Havens et al. Publication No. 20070063048 in. 例如,应用在接触区域互相接触并位于绝缘腔室内的第一绝缘流体和第二导电流体组成流体透镜。 For example, application of contacts and the first insulating fluid located in the chamber and a second insulated conductive fluid composed of a fluid lens in the contact area with each other. 布置第一电极在该绝缘腔室的壁的外表面,其位于该绝缘流体上面。 A first electrode disposed on the outer surface of the insulating wall of the chamber, which is located above the insulating fluid. 第二电极连接所述导电流体。 A second electrode connected to the conductive fluid. 当在第一和第二电极之间建立了电压,产生了电场,其根据所述电湿润原理,改变了相对于绝缘流体容器表面的所述导电流体的湿润特性,以至于所述导电流体使所述绝缘流体移动和变形。 When between the first and second electrodes to establish a voltage, an electric field generated which according to the principle of electro-wetting, changing the wetting properties of the surface with respect to the insulating fluid container of the conductive fluid, said conductive fluid so that The insulating fluid movement and deformation. 因为在两种流体之间的界面形状被改变,获得了焦距、该透镜焦点、或光轴方向的变化。 Because the change in shape of the interface between the two fluids, get the focal length of the lens focal point, or changes in the optical axis direction.

[0022] 也可以使用微型泵控制系统来控制流体透镜,例如描述在Havens等人的US专利申请公开第20070080280号中。 [0022] The micropump may also be used to control the fluid lens control system, such as described in Havens et al., US Patent Application Publication No. 20070080280 of. 这样的系统可以包括与可变形薄膜有力传递的流体腔室或容器。 Such a system may include a fluid chamber or container and the deformable membrane powerful transmission. 可以具有单个这样的腔室,其包括机械力元件或被机械力元件作用,例如,活塞,用来推动流体到所述薄膜或从所述薄膜将它抽回来。 May have a single such chamber, which element comprises a mechanical force or a mechanical force element acts, e.g., piston, to push the fluid into the film or film from said pumping it back. 可选地,可以有一个或多个第二腔室,可以使用其增加流体到主要腔室或从主要腔室抽回流体,该主要腔室与所述薄膜是有力的传递;并且可以使用机械力元件影响流体在主要和次要腔室之间的移动。 Alternatively, there may be one or more second chambers, which can be used to increase the main fluid chamber or withdrawing fluid from the primary chamber, the main chamber and the transfer film is strong; and can use mechanical force elements affect the fluid moving between the primary and secondary chambers. 在这些系统中,当机械力元件可以被电力驱动时,实际施加在界面上以便改变其形状的力是机械的。 In these systems, when a mechanical force element may be power driven, is actually applied at the interface so as to change the shape of the force is mechanical.

[0023] 控制流体透镜操作的其他方法包括使用液晶材料(Nishioka的US专利第6437925 号)、使用压力(Widl的US专利第6081388号)、在可重配置的透镜中使用弹性材料(Rogers 的US专利第4514048号)、和使用微机电系统(根据首字母也被称为MEMS) (Gelbart的US 专利第6747806号)。 [0023] Other methods to control fluid lens operation includes the use of a liquid crystal material (Nishioka of US Patent No. 6,437,925), the use of pressure (Widl of US Patent No. 6,081,388), the use of an elastic material (Rogers of the US in reconfigurable lenses Patent No. 4,514,048), and use of microelectromechanical systems (also referred to in accordance with the first letter MEMS) (Gelbart in US Patent No. 6,747,806).

[0179] 在图18实施例中的无涂层区域116是没有柔性电极涂层的区域,这个涂层可以覆盖除了无涂层区域116之外柔性构件21的内和外表面的剩余部分。 Examples uncoated region [0179] In the embodiment of FIG. 18 flexible electrode region 116 is not coated, the coating can cover the remaining portion except the uncoated region 116 and the outer surface of the flexible member 21. 为了以光透明材料的形式提供绝缘层90以允许光从那里穿过,绝缘层90可以包括合适的光透明材料,其实例包括可以从3M获得的型号为VHB4910和可以从NUSIL获得的CF19-2186的丙烯酸(Acrylie)。 In order to form an optically transparent material to provide an insulating layer 90 to allow light to pass there through, the insulating layer 90 may include a suitable optically transparent material, examples of which include models available from 3M to VHB4910 and can be obtained from the NUSIL CF19-2186 acrylic (Acrylie). 为了制造如图18实施例所示的柔性构件21,可以将光学透明弹性体绝缘材料旋转固化到承载衬底(玻璃基片)从而形成单一薄膜。 The flexible member 18 in order to produce the embodiment shown in FIG. 21, can be optically transparent elastomeric insulating material cured to a rotation of the carrier substrate (glass substrate) to form a single film. 可以在高温下固化该薄膜。 The film may be cured at elevated temperatures. 在固化之后,可以将该薄膜和该衬底及电化学涂层分开以在除非涂层区域116之外形成柔性电涂层。 After curing, the film and the substrate may be electrochemical coating and coating separated from outside region 116 to form a flexible electrically unless coatings. 可以将该形成的柔性构件切成合适尺寸并安装。 The flexible member may be formed of cut to size and install it. 在另一方面,当施加电压来收缩柔性构件21,将导致最初大体上在轴15外周方向产生的力被大体上在轴15指向透镜元件10的方向上以如下的方式施加到可变形透镜元件10,使得透镜元件的凸度变大。 On the other hand, when a voltage is applied to shrink the flexible member 21, will result in the force initially generated substantially in the outer circumferential direction of the shaft 15 is substantially pointing in the direction of the shaft 15 of the lens element 10 is applied in the following manner to the deformable lens element 10, so that the projection of the lens element becomes large. 利用环形定型并布置在轴15周围的孔16及利用适于与可变形透镜元件形状匹配的柔性构件21,柔性构件21的收缩将导致大体上在轴15方向上指向可变形透镜元件的力是被施加在布置在轴15的外周周围并且空间上远离轴15的多个点上的。 The use of an annular shape and arranged around the shaft 15 in the bore 16 and the use of the flexible member may be adapted to match the shape of the deformable lens element 21, the contraction will cause the flexible member 21 is substantially pointing in the direction of the shaft 15 forces the deformable lens element is It is applied is arranged around the outer circumference of the shaft 15 and the upper space of more than 15 points away from the shaft on. 当将在图18实施例中驱动装置20施加到透镜元件10上的力描述为是大体上在透镜元件轴15方向上的时候,可以理解如果将施加的力分解为法向(轴向)和切向(与轴垂直),那么可以期望在图18实施例中各成分力向量组成比在这里参考图1-9已描述的实施例中具有更高百分比的切向成分力向量。 When the embodiment is applied to the drive means 20 forces the lens element 10 is described as being substantially in the direction of the axis of the lens element 15 when the force is applied will be appreciated that if the decomposition is normal (axial) and 18 in the embodiment of FIG. tangential (perpendicular to the shaft), you can expect here than in Reference Examples 1-9 cut has been implemented with a higher percentage of the components depicted in Figure force vector components consisting of the force vector in the examples in Figure 18.

[0219] 参考下面图27的流程图描述了示例性的自动聚焦算法。 [0219] Referring to the flowchart of FIG. 27 is described below exemplary autofocus algorithm. 在方框1502中终端1000 可以确定第一帧也就是具有曝光周期EXP1的帧是否聚焦对准。 In block 1502, the terminal 1000 may determine whether the first frame is having a frame exposure period EXP1 focus alignment 确定帧是否聚焦对准可以包括检查图像数据帧的“平整度”。 Determine whether the focusing frame alignment may include a frame of image data checking, "flatness." 通过在柱状图中的帧测绘像素值,聚焦不对准的帧将具有在一定强度范围内的相对“平整”像素值强度分布和相对平滑的强度分布。 By mapping the pixel values of the frame in the histogram, the focus is not aligned with the frame will have a certain strength within the range of relatively "flat" pixel values of the intensity distribution and the relatively smooth intensity distribution. 另一方面,可以期望聚焦对准的帧相对于聚焦不对准的帧,在某些强度可以具有大量的像素值入射, 并且在其他强度可以具有充分少的入射。 On the other hand, it may be desirable to focus alignment frame misalignment with respect to the focus frame, it may have a certain intensity incident on a large number of pixel values, and may have sufficient strength in other less incidence. 如果终端1000在方框1502确定目前的帧是聚焦对准的,那么终端1000可以前进到方框1512以将该透镜设置保持在确定为聚焦对准的设置中,并且可以对该帧进行处理。 If the terminal 1000 determines the current frame is aligned with the focus at block 1502, the terminal 1000 can proceed to block 1512 to set the lens focus is determined to remain in aligned arrangement, and the frame can be processed. 该处理可以包括,例如对该帧进行符号解码尝试或可能输出作为被格式化的单帧,或作为被格式化的视频流图像的输出帧到显示器上。 The process may include, for example, attempts to decode the frame symbol or might output is formatted as a single frame, or as a formatted video stream output frame image to the display.

[0220] 如果在方框1502检测的帧不是聚焦对准的,在方框1506的终端1000可以检测具有与在方框1502检测的图像数据帧不同的聚焦设置的帧。 [0220] If at block 1502 detected frame alignment is not focused, at block 1506 of the terminal 1000 can detect and image data have detected frame at block 1502 different frame focus settings. 对于具有“特定透镜设置”的帧, 意味着透镜组合500的聚焦设置在与该帧关联的曝光周期期间被设为该特定透镜设置。 For a frame having a "specific lens setting" it means that the focusing lens assembly 500 is provided with the frame during the exposure period associated with the particular lens setting is set. 如果在方框1504终端1000确定在方框1504被检测的帧是聚焦对准的,那么终端1000可以进行到方框1512以将透镜组合500保持在当前的设置(该设置服从于确定聚焦对准的帧), 并且处理在确定的聚焦对准设置用透镜组合500曝光的一帧或多帧。 If it is determined at block 1504 is frame detection is focused aligned terminal 1000 at block 1504, the terminal 1000 can proceed to block 1512 to the lens assembly 500 is maintained at the current setting (the setting is subject to determine the focus aligned frames), and the process set determined by aligning the focus lens 500 exposed composition one or more frames.

[0221] 进一步参考图27的时序图,如果在方框1506检测的帧在方框1508被确定为不聚焦对准的,那么终端1000可以进行到方框1510以基于在方框1502检测第一帧和在方框1504检测第二帧的处理确定聚焦对准的设置。 [0221] With further reference to the timing chart of FIG. 27, if the frame is detected at block 1506 is determined to be out of focus in the alignment block 1508, the terminal 1000 can proceed to block 1510 to block 1502 based on the detection of the first frame and the second frame processing block 1504 to determine the focus detecting the alignment settings. 这种处理可以包括估评估透镜设置的改变对帧的平整度的影响(例如,可以运行算法,以便如果通过移动透镜设置从第一设置到比第一设置具有更短最佳焦距的第二设置时所捕获的帧变得更平整[较少的聚焦对准],那么相应于所述处理将该透镜设置设为比第一设置具有更短最佳焦距的某个设置)。 Such processing may include changing the estimated impact assessment of the lens setting of the flatness of the frame (e.g., run the algorithm, so that if by moving the lens arrangement has a shorter best focus from the first set to the second set than the first set When the captured frame becomes flat [less aligned focusing], then the processing corresponding to the lens setting to a setting having a best focal length shorter than the first set). 当确定了聚焦对准设置,终端1000将透镜组合500设在确定的聚焦对准设置上,并且可以前进到方框1512来处理具有与该透镜设置被设为确定的聚焦对准设置的时间一致的曝光周期的帧。 When it is determined to set the alignment of the focus, the lens assembly 500 of terminal 1000 disposed in the focus setting determines the alignment, and may proceed to block 1512 to process with time, and the focus lens setting is set to determine the set of consistent alignment exposure period of the frame. 如果在方框1506检测的帧在方框1508被确定为聚焦对准的,那么终端1000可以进行到方框1512以将透镜组合500保持在当前的透镜设置上,并且在确定的聚焦对准设置中用透镜组合处理500曝光的一帧或多帧。 If the frame is detected in block 1506 at block 1508 is determined to be focused aligned, the terminal 1000 can proceed to block 1512 to the lens assembly 500 is maintained at the current setting of the lens, and the focus setting determines the alignment of Treatment with a combination of the lens 500 exposing one or more frames.

[0222] 现在转到图28的视图,显示和描述了用来结合到并支撑图25的部件的移动手持外壳1091。 [0222] Turning now to FIG. 28 is a view, shown and described the move to bind to and support member 25 of FIG handheld package 1091. 图28的无品牌形式要素表示该移动电话的共同形式要素,例如蜂窝电话、或用在数据采集应用中的便携式数字采集终端。 No brand in the form of elements of FIG. 28 indicates that the mobile phone common form elements, such as a cellular phone, or data acquisition applications in portable digital collection terminal. 终端1000也可以以其他类似形式结合进一个外壳,例如数字照相机或可携式摄像机形式要素。 Terminal 1000 can also be incorporated into a case with other similar forms, such as a digital camera or a camcorder form factors.

[0223] 如在图28中所示的显示器1097的显示菜单所指示的,终端1000可以具有多个操作者可选的配置。 [0223] As shown in the display 28 to display the menu 1097 of FIG indicated, terminal 1000 may have a plurality of operator selectable configuration. 每种配置可以具有与透镜设置关联的不同控制算法。 Each configuration can have different settings associated with the lens control algorithms. 也就是,终端1000 响应于正被激活的触发信号控制透镜组合500的透镜设置根据所选配置而改变的方法。 That is, the terminal 1000 is being activated in response to a trigger signal control lens lens setting 500 configuration change according to the selected combination of methods.

[0224] 在下面的表D概述了各种操作者可选的配置。 [0224] In the following Table D summarizes the various operator selectable configuration. 在配置1,终端1000根据预定模式在各种透镜设置之间循环。 In the configuration, terminal 1000 according to a predetermined pattern circulating among various lens settings. 特别地,在配置1,终端1000在每个曝光周期之后从一个透镜设置变化到下一个透镜设置,并且接着在用最远聚焦设置(L7)已经捕获到帧之后,以1递减该透镜设置。 In particular, in one configuration, the terminal 1000 changes from a lens disposed after each exposure period to the next lens setting, and then after using the farthest focus setting (L7) has captured frames to a decrement the lens setting. 在配置2,终端1000相应于正被激活的触发信号1202,根据适当模式改变终端1000的透镜设置。 In Configuration 2, 1000 corresponding to the positive terminal of the trigger signal is activated 1202, changing lens setting terminal 1000 according to the appropriate mode. 在表D中,配置2的这排项目表示当终端1000执行自动聚焦算法时可表现出的透镜设置变化模式。 In Table D, the configuration of the row item represents 2 when the terminal 1000 may exhibit the lens setting changes autofocus algorithm execution mode. 对于帧1和帧2 (具有关联曝光周期1和2),透镜设置是前进的。 For frames 1 and 2 (with the associated exposure periods 1 and 2), the lens setting is forward. 然而,在帧1和帧2被处理之后,如果帧1和帧2的处理表明设置L2是聚焦对准的, 那么后续的帧,例如相应于EXP4的帧4,可以具有L2的透镜设置。 However, after the frames 1 and 2 are processed, the processing if frames 1 and 2 indicate that the focus setting L2 is aligned, then the subsequent frames, e.g., corresponding to EXP4 frame 4, the lens may have a set L2. 在配置3,终端1000不改变透镜设置,而将终端1000的透镜设置维持在固定的短聚焦位置。 In configuration 3, the terminal 1000 does not change the lens setting, and the terminal 1000 is maintained at a fixed lens setting short focus position. 例如当已经知道要在靠近视图符号解码的固定位置使用终端1000时,可以选择配置3。 For example, it has been known to be used when the terminal 1000 in a fixed position near the symbol decoding of view, you can select the configuration 3. 在配置4,终端1000不响应于正被维持在激活状态的触发信号而改变透镜设置,而将终端1000的透镜设置维持在固定的远聚焦位置。 In configuration 4, terminal 1000 is not being maintained in response to the trigger signal active lens setting is changed, and the terminal 1000 is maintained at a fixed lens setting far focus position. 例如当要使用终端1000来捕获相应于远场景物体的图像数据帧的时候,配置4是有用的。 For example when you want to use the terminal 1000 to capture the object corresponding to the distant scene when the frame of image data, configuration 4 is useful. 在配置5,终端1000适应性地变化透镜设置,直到确定了聚焦对准的透镜设置并且随后用该聚焦设置捕捉到预定数目的帧。 In Configuration 5, 1000 terminal adaptively change the lens settings until you determine the focusing lens setting and then aligned with the focus setting to capture a predetermined number of frames. 例如当使用终端1000来捕获图像数据帧的静止图像时候,配置5是有用的。 For example, when using a terminal 1000 to capture a still image frames of image data when the configuration 5 is useful. 从在表D中相应于配置5的横排数据可以发现,终端1000可以处理帧1和帧2以确定聚焦对准设置,移动该透镜设置到确定的聚焦对准设置,在该确定的聚焦对准设置捕捉多个帧,处理这些帧,以及接着使触发信号无效。 Table D from the respective horizontal data at 5 configuration can be found, the terminal 1000 can handle frames 1 and 2 in order to determine the focus in alignment, moving the focus lens is set to determine the alignment settings, focusing on the determination Quasi set capture multiple frames, to deal with these frames and then the trigger signal is invalid. 在确定的聚焦对准设置下捕捉的多个帧可以被平均或者另外被处理用来减小噪声。 A plurality of frames at the focus setting determines the alignment of capture may be averaged or otherwise processed to be used to reduce noise. 关于配置6,配置6与配置1相似,除了当根据配置6操作,终端1000跳过透镜组合设置,并且在前进到下个设置之前,在每个用于多个帧的连续的设置处维持该透镜设置。 About Configuration 6 Configuration 6 1 configuration is similar, except when operating according to configuration 6, 1000 Skip the lens combination terminal settings, and before proceeding to the next set, maintained at each successive set for a plurality of frames lens setting. 关于配置7,配置7 表示当终端1000执行简化的自动聚焦算法时的操作,在其中终端1000简单顺序地为每个新的帧步进所述透镜设置,测试每个得到的帧的聚焦程度,并且在确定为聚焦对准的第一帧处维持该帧。 7 on the configuration, the configuration 7 shows a simplified when the terminal 1000 performs the autofocus algorithm, terminal 1000 simply set sequentially for each new step of the lens frame in which to test the degree of focus of each frame obtained, and maintaining the focus frame is determined to be aligned in a first frame. 注意关于曝光周期EXP4,当处理具有曝光周期EXP3的帧时,终端1000可以前进该透镜设置到不聚焦对准的设置。 Note regarding the exposure period EXP4, when dealing with an exposure period EXP3 frame, terminal 1000 can not advance the lens is set to focus alignment settings.

[0230] 本发明提供聚焦模块以用在流体透镜中,其具有很少的移动部分,并且不要求存在多个用于该透镜的流体部件的腔室或贮液器。 [0230] The present invention provides a focus lens module for use in a fluid, which has few moving parts and does not require the presence of more than one chamber or reservoir for fluid part of the lens.

[0231] 更特别地,本发明专注于可以包括如下元件的聚焦模块: [0231] More particularly, the present invention may include the following elements focused on the focusing module:

[0232] 1)边界元件,其可以是刚性的(例如玻璃或塑料)可变形的(例如弹性体); [0232] 1) the boundary element, which can be rigid (e.g. glass or plastic) can be deformed (e.g., elastomers);

[0233] 2)隔离元件,其插入在所述边界元件和聚焦元件之间; [0233] 2) isolation element inserted between the boundary element and focusing elements;

[0234] 3)聚焦元件,在至少一个方向上可变形的(例如流体或弹性体); [0234] 3) focusing element, in at least one direction deformable (e.g., fluid or elastomer);

[0235] 4)压力元件,其从所述变形元件到所述聚焦元件传输力; [0235] 4) pressure element to focus the force transmission element from the deformable element;

[0236] 5)作用在所述聚焦元件上的变形或驱动装置元件(例如人造弹性体或电致动聚合体); [0236] 5) in the deformation or the drive element of the focusing element (such as artificial elastomer or electrically actuated polymers);

[0237] 6)传导元件,用来传导电信号或激励到所述可变形元件; [0237] 6) conductive elements for conducting electrical signals or incentives to the deformable element;

[0238] 7)外壳元件,为组合提供物理外壳或支撑物;以及 [0238] 7) housing element, is a combination of physical enclosure or provide support; and

[0239] 8)功率源,大体上位于所述聚焦模块的外部,用来给所述传导元件提供能量。 [0239] 8) power sources, generally located outside the focusing module, to provide energy to the conductive element.

[0240] 正如这里将进一步解释的,对于可操作聚焦模块来说所有的这些元件不都是必需的。 [0240] As used herein will be further explained, the operational focus module for all of these components are not all necessary. 例如,所述可变形元件也可以具有作为所述隔离元件的作用,所述隔离元件可以省略, 当通过使用如下文讨论的唯一填充流体的元件来提供所述透镜时,所述压力元件也可以省略,通过所述变形元件直接作用在所述聚焦元件上,并且所述外壳元件是重要的容器,其他的那些元件都可以放置在其内,或者可以将它们组装在其内,并且它的功能可以由聚焦装置在其中工作的装置或设备中的其他结构元件来提供。 For example, the deformable element may also have a function as the spacer element, the spacer element can be omitted, when the element is discussed below by using only the fill fluid to provide the lens, the pressure element can also be omitted by the deformation element acts directly on the focusing element and the housing element is important to the container, that other elements can be placed therein, or they may be assembled therein, and its function wherein the apparatus or device can work in the other structural elements provided by the focusing means.

[0241] 所述边界元件可以是刚性的,例如玻璃或塑料,或可变形的,例如弹性体。 [0241] The boundary member may be rigid, such as glass or plastic, or deformable, such as an elastomer. 当期望作为变形力被施加到所述聚焦元件上的结果所述边界元件不承受任何变形时,如果所述边界元件的弹性是以下这样即是足够的,既当所述聚焦元件是在最大变形时,所述边界元件响应于将被传输给它的力或能量而不会变形。 When it is desired as a deforming force is applied to the focus on the results of element boundary element is not subjected to any modification, if the boundary element are the following so that is enough, both when the focusing element is at maximum deformation When the boundary element will be transmitted in response to a force or energy to it without deforming. 例如,如果所述聚焦模块包括边界元件、隔离元件和聚焦元件,而所述聚焦元件包括流体和可变形薄膜,其中所述流体被夹持在所述边界元件和所述薄膜之间,那么使用压力元件通过施加压力到所述流体上来使所述聚焦元件变形,不管是通过在所述边界元件的方向上按压所述薄膜,还是通过减小所述流体在所述边界元件和所述薄膜之间(例如,通过环形紧固)的厚度。 For example, if the focusing module comprises boundary elements, spacer elements and the focusing elements, and said focusing element comprises a deformable membrane and a fluid, wherein the fluid is sandwiched between the film and the boundary element, then the use of applying pressure to the pressure member through said fluid onto said focusing element is deformed, either by the boundary element in the direction of pressing the film, or by reducing the fluid in the boundary element and the thin film Room (e.g., through the annular fastening) thickness. 如果期望所述边界元件不变形, 那么当所述压力元件施加最大的压力到所述流体上时,它应该是足够刚性地保持平整的。 If desired the boundary element is not deformed, the maximum pressure when the pressure is applied to the fluid on the element, and it should be rigid enough to keep the flat. 换句话说,当期望所述边界元件在聚焦模块工作期间不变形,仅仅需要所述边界元件在这种情况下不变形,而不需要它是完全刚性的或不能变形。 In other words, when the desired deformation of the boundary element in the focusing module during operation, need only the boundary element in this case is not deformed, without the need for it is not completely rigid or deformable.

[0242] 如所述的,可以使用玻璃,并且多种光学玻璃材料是商业上可获得的,例如,可从美国纽约Corning 的Corning Display Technologies 获得的Corning® EAGLE2000 Display Grade玻璃,和可以从美国宾夕法尼亚州Duryea的Schott North America有限公司获得的N-BK 7玻璃。 [0242] As described, a glass, and a variety of optical glass materials are commercially available, for example, can be obtained from the Display Technologies Corning, New York's Corning Corning® EAGLE2000 Display Grade glass, and from Pennsylvania Duryea state of Schott North N-BK 7 Glass America Limited obtained. 所述边界元件可以是适合厚度的,包括从大约0. Imm到大约1mm,例如0. 2、0· 3、0. 4mm。 The boundary member may be suitable thickness ranging from about 0. Imm to about 1mm, for example, 0. 2,0 · 3,0. 4mm.

[0243] 所述隔离元件可以是任意一种材料,包括金属、塑料和陶瓷制品,依赖于它期望的功能。 [0243] The spacer element may be any material, including metals, plastics and ceramics, depending on its desired functionality. 当所述功能限制为隔离所述边界元件和所述聚焦元件时,可以是与它将接触的其他材料共存的任何材料,包括聚焦流体,例如不锈钢。 When the function is limited to the boundary of the isolation element and the focusing element, other materials may be any material in contact with it will coexist, including focusing a fluid, such as stainless steel. 当还期望它在它本身与所述边界元件和/或聚焦元件之间提供密封,所述隔离元件可以是双侧的带。 When it is also desirable to provide a seal between itself and the boundary element and / or focusing element, the spacer element can be double-sided tape. 当期望它作为所述变形或驱动元件工作时,它可以是如这里进一步讨论的人造弹性体或电致动聚合体。 When it is desired as the deformed or drive components work, it may be an elastomer or synthetic as further discussed electric actuator polymers. 当期望所述隔离元件既密封所述边界和/或聚焦元件,也作为所述变形或驱动元件工作时,它可以是附加提供有响应于电激励的变形和驱动功能的双侧带,例如,可以从包括从美国德克萨斯州Fort Worth的Hillas Packaging有限公司的多个供应商获得的3M VHB带,像Double Coated Acrylic Tape 4910。 When it is desired to seal the both the spacer element boundary and / or focusing elements, but also when the deformation or to work as a driving element, which can be provided with additional electrical excitation in response to the double-sided tape deformation and drive functions, for example, 3M VHB tape can be obtained from the group consisting from Fort Worth, Texas, the Hillas Packaging Co., multiple vendors, like Double Coated Acrylic Tape 4910.

[0244] 为了使聚焦流体更容易填充到所述流体腔室,所述隔离元件可以具有缝隙或端口,如图29所示的元件2a。 [0244] In order to make it easier to focus a fluid filled into the fluid chamber, the spacer element may have a slit or port, as shown in Fig. 29 element 2a. 在所述流体腔室已经被用聚焦流体填满之后,可以通过将阻止流体流出所述腔室的任何方法将该缝隙或端口密封,并且当响应于所述变形元件的驱动时将充分地经受住所述聚焦流体施加的压力。 It has been used to fill after focusing fluid can be prevented by any means out of the fluid chamber or port seal the gap, and when the deformable element in response to the drive will be fully subjected to the fluid chamber live the focusing fluid pressure applied. 例如,可以使用环氧粘合剂提供所述密封。 For example, an epoxy adhesive may be used to provide the seal.

[0245] 所述聚焦元件可以是单个的部件,例如填满流体的弹性体、聚合体或塑料,例如具有塑料弹性复原性的填满油的透明弹性体材料。 [0245] The focusing element may be a single component, such as fill fluid elastomer, or a plastic polymer, an elastomeric material such as a transparent plastic filled elastic recovery of oil. 可选地,所述聚焦元件可以是具有被夹住或夹持在所述边界元件和所述可变形聚焦薄膜之间的聚焦流体(例如水或油)的两个或多个的部件,在其配置中所述聚焦流体和所述聚焦薄膜将一起组成所述聚焦元件。 Alternatively, the focusing element may be clamped or sandwiched with the boundary between the element and the deformable membrane focus focus fluid (e.g., water or oil) in two or more parts, and in its configuration and the focus of the focusing fluid film will form along the focusing element. 当使用薄膜,合适的材料将包括聚二甲基硅氧烷,或PDMS,例如可以从美国密歇根州中部的Dow Corning公司获得的成套Sylgard® 184硅树脂弹性体。 When using film sets Sylgard®, suitable materials will include polydimethylsiloxane, or PDMS, for example, may be obtained from the United States in the middle of Michigan company Dow Corning 184 silicone elastomer. 可以基于例如所述聚焦模块需要的尺寸因素选择所述薄膜的厚度,例如可以是从大约0. Imm到大约1mm,例如0. 2,0. 3、 0. 4mm。 It may be based on factors such as the size of the focusing module to select desired thickness of the film, for example, from about 0. Imm to about 1mm, for example, 0. 2,0. 3, 0. 4mm.

[0246] 当使用聚焦流体,应该通过与其他材料的兼容性、在使用下的稳定性、将被使用在预期温度下的忍耐性和类似因素来选择它的性能。 [0246] When using a focused fluid, should be through compatibility with other materials in the stability under use and will be used in the patient and like factors expected temperatures to choose its performance. 可以使用光学流体和光学级油,例如光学级矿物油。 You can use the optical fluid and optical-grade oil, such as optical-grade mineral oil. 一种合适的光学流体是可以从美国新泽西州Cedar Grove的Cargille-Sacher Laboratories有限公司获得的A型沉浸油。 A suitable optical fluid is A type may Co., Ltd. received from Cedar Grove, New Jersey, United States of Cargille-Sacher Laboratories immersion oil. 另一种合适的光学流体是可以从美国密苏里St, Charles的Arch TechnologyHolding有限公司获得基于Santovac®聚苯醚的光学流体SL-5267。 Another suitable optical fluid is available Santovac® polyphenylene ether-based optical fluid SL-5267 from Missouri St, Charles's Arch TechnologyHolding Limited. 也可以使用水,例如去离子水。 Water may also be used, e.g., deionized water.

[0247] 如前面注意到的,所述边界元件和所述聚焦元件必须是光学透明的,至少其中的一部分用来传输图像信息。 [0247] As previously noted, the boundary element and the focusing element must be optically transparent, at least a portion of which is used to transmit the image information. 因此,当为了简化制造和组装,每个元件整体通常是光学透明的,所述边界元件和聚焦元件的其中之一或者两个的外环部分的至少一部分是半透明的或不透明的也是可能的,其环绕着光学透明的内部。 Thus, when in order to simplify manufacture and assembly, each of the element as a whole is usually optically transparent, wherein at least a portion of one of said boundary element and the focusing element or the outer portion of both of translucent or opaque also possible , which surrounds the optically transparent internal.

[0248] 当由于折射损失,期望使得光通过所述聚焦模块传输的损失最小化,所述边界元件和聚焦元件选择的材料应该具有相似折射率。 [0248] When the loss due to refraction, it is desirable that the light transmitted through the focusing module to minimize losses, the border element and the focusing element selected material should have a refractive index similar. 例如,当所述聚焦模块包括玻璃边界元件、 聚焦流体、和聚焦薄膜,我们应该考虑到所述聚焦流体和所述边界元件折射率的不同、所述聚焦流体和所述聚焦薄膜折射率的不同。 For example, when the focusing module includes a glass border element, focusing fluid, and focus the film, we should take into account the focusing fluid and the boundary element different refractive indices, the focusing fluid and the focus of different refractive index film . 折射率越不同,当光企图通过一种材料(例如玻璃)到另一种材料(例如沉浸油)时将会损失更多的光用来反射。 The more different refractive indices, when attempting to light through a material (e.g. glass) to another material (e.g., oil immersion) will lose more time for the reflected light. 相反,折射率越靠近, 将会损失更少的光用来反射。 On the contrary, the closer the refractive index, will lose less light for reflection. 在本文中所述折射率将理想化地相同,并且优选是在大约+/-0. 001到0. 1之内,例如大约0. 002。 The refractive index of the same idealized herein, and preferably within about +/- 0.001 to 0.1 of, for example, about 0.002. 然而,也可以有这种情况,折射率不同可能是有优点的,例如减少某些类型的像差。 However, there may be such a case, the refractive index differences may be advantageous, for example, to reduce certain types of aberrations.

[0249] 也可以改变在变形区域上的所述聚焦薄膜的厚度,当保持本发明激活的可变性时,其将形成具有非球面特征的结构。 [0249] The change may be focused on the deformed region of the thickness of the film, when the retainer of the present invention is activated variability, which will form a structure having aspheric characteristics.

[0250] 选择具有相对高折射率的聚焦流体将减小为获得给定的焦距变化而必需的变形量。 [0250] Selecting a focus fluid having a relatively high refractive index to decrease the amount of deformation in order to obtain a given focal length changes required. 例如,合适的折射率可以是在从大约1. 3或大约1. 5到大约1. 6或大约1. 7的范围内, 例如大约1. 5或大约1. 6的折射率。 For example, a suitable refractive index may be from about 1.3 or about 1.5 to about 1.6 or within the range of about 1.7, e.g., a refractive index of about 1.5 or about 1.6 in.

[0251] 类似地,所述压力元件也可以是任意各种材料,包括金属、塑料和陶瓷制品。 [0251] Similarly, the pressure element may be any of a variety of materials, including metals, plastics and ceramics. 材料的选择可以根据与其他材料的兼容性以及根据对所述变形元件施加的力所期望的响应。 The choice of materials according to the compatibility and in accordance with the force applied to the deformable element of the desired response with other materials. 如果期望所述压力元件不使它本身变形,它应该是无弹性材料,例如金属、陶瓷制品或塑料。 If desired the pressure deformation member itself does not make it, it should be non-elastic material, such as metal, ceramics or plastics. 然而,如果期望或需要所述压力元件响应于所述变形元件改变它的形状或配置,它应该由可变形材料构成,例如弹性体。 However, if desired or necessary in response to the said pressure element is deformable element change its shape or configuration, it may be formed of a deformable material, such as an elastomer.

[0252] 所述变形元件是通过以间接(例如通过所述压力元件)或直接改变应用到所述聚焦元件上的力而对控制信号作出响应的部件。 [0252] The deformable element is by indirect (e.g., via the pressure element) or directly change the force applied to the element on which the focusing control signal responsive member. 特别适合用作所述变形元件的是电致动或电传导聚合体驱动装置。 Particularly suitable for use as the deformable element is electrically actuated or electrically conductive polymer drive means. 一个实例是可以通过美国加利福尼亚Menlo Park的Artificial Muscle有限公司获得的Electroactive PolymerArtificial Muscle禾口/或the Universal Muscle Actuator platform,另一个实例是可以通过日本大阪EA MEX公司获得的导电聚合体驱动装置。 One example is through the United States Menlo Park, California Artificial Muscle Limited obtained Electroactive PolymerArtificial Muscle Hekou / or the Universal Muscle Actuator platform, another example is the drive with the conductive polymer Osaka EA MEX company acquired.

[0253] 当所述变形元件是人造弹性体或电致动聚合体,将所述变形元件提供为类似于肌纤维层的两层或多层是或许可能的。 [0253] when the deformable element is a synthetic elastomer or electrically actuated polymer, said deformable element is similar to the muscle fiber layers provide two or more layers is probably possible. 而且,当各层在特定的方向上响应于电激励而变形时, 这种效果可以被用来为该整个分层组合选择给定运动方向。 Moreover, when the layers in a specific direction in response to an electrical excitation and deformation, this effect can be used for the entire layered combination selection to set the direction of motion. 这样,可以要求获得例如在其中已经安装了各层人造弹性聚合体到如图44所示的矩形固体形状的变形元件,然而响应于电激励,即使无弹性结构的使用限制了运动的一个或多个方向,或以特殊的方式影响运动,该矩形固体也可以如图45所示向上卷起,如图46所示侧面延伸,如图47所示向下弯曲,或者甚至扭曲。 Thus, for example, you can request which has been installed in the layers of artificial elastic polymer deformable member body to a rectangular solid shape as shown in FIG. 44, but in response to electrical excitation, even using inelastic structure limits a movement or direction, or in a special way affect the movement of the rectangular solid as shown in Figure 45 to be rolled up, the side shown in FIG. 46 extends downwardly curved as shown in FIG. 47, or even distorted. 图45和47描述了矩形固体的不均勻曲面,其可以通过例如使用框架或其他外部结构(未示出)限制该矩形固体的一部分、通过将该固体的一部分锚定或固定到无弹性元件上、或通过包括该固体的层的适当结构或选择来实现。 Figure 45 and 47 describe the uneven surface of the rectangular solid, which may be used by, for example, or other external frame structure (not shown) to limit a portion of the rectangular solid, a portion of the solid by anchoring or fixing onto the inelastic member or by including the appropriate structure or select the solid layer to achieve. 可选地,该矩形固体可以表现出沿着它的长度的常数曲率半径,例如,更长一侧形成的弯曲可以表示沿着圆的圆周的弧。 Alternatively, the rectangular solid can exhibit a constant radius of curvature along its length, e.g., longer curved side may be formed along the circumference of the circle indicates the arc. 当多个电子电路存在于所述可变形元件中时,电激励可以包括供应电压到少于全部的电路,和/或与这些电路极性相反的供电电压。 When a plurality of electronic circuits are present in the deformable member, the electrical stimulus may comprise less than the full supply voltage to the circuit, and / or circuit supply voltage polarity opposite to these.

[0254] 这些形状上的改变可以进一步通过所述分层来实现,应用具有它或它们自己的电子控制电路的每个层、或这些层的组合;或者,所述变形元件可以被将它的移动限制在一个或多个方向上、并因此迫使在期望的方向上移动的框架或其他结构所限制。 [0254] These shape changes can be further achieved through the hierarchical, or their application has its own, or a combination of these layers in each layer of the electronic control circuit; Alternatively, the deformable member may be of it movement restrictions in one or more directions, and thus forced to move in the desired direction of the frame or other structure is limited. 通过制造不相同尺寸的各层可以实现类似的效果,例如,在两层结构中,如果一层比另一层长了一定的尺寸,随后对这两层的驱动将大体上在更短的那个层的方向上产生弯曲。 By making the layers are not the same size can achieve a similar effect, for example, in a two-tier structure, if one longer than the other a certain size, then these two drivers will be substantially shorter in the bending the direction of the layers. 通过参考在图29、 30和36所示的变形元件5,可以更好地理解这种作用方式。 5 by reference deformable element 29, 30 and 36 as shown, this effect may be better understood manner. 在图36中,例如,指状或带状元件5a通过包括两层或多层聚合体而起作用,其中更靠近所述聚焦薄膜的层比那些靠近所述边界元件的层更短。 In Fig. 36, for example, fingers or belt element comprises two or more layers 5a through polymer that functions, wherein the thin film layer is closer to the focusing layer is shorter than those near the border element. 当变形元件5被驱动,这种各层在尺寸或大小上的差别将导致每个指状元件5a卷曲或弯曲向所述压力元件,将它压迫向所述聚焦薄膜的方向,并且这个移动将依次使所述聚焦薄膜变形为凸透镜形状。 When the deformable element 5 is driven, the difference in size of each layer or size will cause each finger 5a crimped or bent towards the pressure member, it presses the film to the focus direction, and this will move turn the focus of the film is deformed into a convex shape. 可选地,在该结构中可以包括非变形层,在这种情况下,所述变形层或各层将大体上向或在所述非变形层的方向上弯曲或移动。 Alternatively, the structure may be included in the non-deformed layer, in this case, the deformable layer or layers to be substantially or bent or moved in the direction of the non-deformable layer.

[0255] 图48和49表示双凸电致动聚合体薄膜透镜。 [0255] FIG. 48 and 49 represents a double convex electrically actuated polymer film lenses. 在这个实施例中,当两个表面都是可变形薄膜时,构造双凸透镜是可能的。 In this embodiment, when the two surfaces are deformable membrane, it is possible to construct a lenticular lens. 而且,因为不同的薄膜直径,所述薄膜的两个表面可以具有不同的表面曲率。 Moreover, because of the different diameters of the film, both surfaces of the film may have a different surface curvature. 在所述薄膜的材料和厚度方面的不同也可以被用来制造不同表面形状。 Material and thickness of the different aspects of the film may also be used to make different surface shapes.

[0256] 图50表示多个可变形薄膜透镜组合,并且应该注意到变焦透镜可以应用两个(或多个)由电致动聚合体驱动的透镜和其他固定元件来实现。 [0256] FIG. 50 shows a combination of a plurality of lenses deformable membrane, and should be noted that the zoom lens can be used two (or more) driving a lens and other fixed element by an electric actuator to achieve the polymerization.

[0257] 图51和52表示通过将普通透镜布置在电致动聚合体机械装置中,加上附加固定元件可以制作出用于紧凑自动聚焦和变焦应用的可变定位透镜元件。 [0257] Figures 51 and 52 showing the lens arrangement through the common electric actuating mechanism in a polymer, plus an additional fixing element can produce variable positioning member for compact lens autofocus and zoom applications.

[0258] 如注意到的,所述变形元件可以直接作用在所述聚焦元件上,就象直接与它接触。 [0258] As noted, the deformable element can act directly on the focusing element, as direct contact with it. 可选地,所述变形元件产生的力可以通过一个或多个中间设备或元件被传输到所述聚焦元件。 Alternatively, the force generated by the deformable element may be transmitted via one or more intermediate devices or elements to the focusing element. 作为一个实例,压力元件可以连接到所述聚焦元件或与所述聚焦元件接触,并且所述变形元件可以压在所述压力元件上,其传输力到所述聚焦元件上。 As an example, the pressure element can be connected to or in contact with the focusing element focusing element and the deformable member may be pressed against the pressure member, which force is transmitted to the focusing element. 在一个实施例中,所述压力元件可以是圆形的,或圈形,并且可以直接或间接与所述聚焦元件的外环部分接触。 In one embodiment, the pressure element may be circular, or ring-shaped, and the focus can be either directly or indirectly with the outer portion of the contact element.

[0259] 所述导体元件传输所述控制信号给所述变形元件。 [0259] The element transmission conductor of the control signal to the deformable element. 在所述变形元件响应电信号情况下,如在电致动聚合体情况下,它基本上起导体作用用来从所述功率源传导电动力到所述变形元件上。 In the case where the deformable element in response to an electrical signal, such as in the electrically actuated polymer case, since it is substantially a conductor for conducting electrical power from said power source to said deformable element. 因此它应该是导电性的,优选是高导电性的,至少在相对部分,并且可以包括导电材料,包括导电金属例如铜、导电塑料、或者被用碳涂保护层或涂材料以产生其导电性的弹性体。 Therefore, it should be electrically conductive, preferably highly conductive, at least partially opposite, and may include a conductive material, comprising a conductive metal such as copper, conductive plastic, or is coated with a protective layer or a carbon coated material to produce a conductivity The elastomer. 特别的例子包括柔性电路板和喷镀或沉淀导电性金属到所述变形元件表面上。 Specific examples include a flexible circuit board and the conductive metal plating or precipitated onto the surface of said deformable element.

[0260] 如在图29中描述的,所述导体元件包括两个部件,每一个在所述变形元件的一侧,并且每个元件具有电接触端口6c用来连接功率源,在这个实施例中所述变形元件将响应于电信号的存在或不存在而被均勻地激活或停止,并且由聚焦元件形成的所述凸半月板将是对称的。 [0260] As depicted in Figure 29, the conductive member comprises two parts, one on each side of said deformable element, and each element having electrical contacts for connecting the power source port 6c, in this embodiment said deformable element in response to the presence or absence of an electrical signal which is uniformly activated or stopped, and the convex meniscus formed by the focusing element will be symmetrical.

[0261] 然而,也应该理解所述导体元件可以包括使所述变形元件的一个或多个部分选择性激励的多个电路,从而允许所述聚焦元件的可调操作,通过使所述凸半月板可以为选择性地不对称的。 [0261] However, it should be understood that the conductive element may comprise one or more portions of a plurality of circuits of the selective excitation of the deformable element so as to allow operation of the focusing element is adjustable, by making the convex half plate may be selectively asymmetrical. 例如,通过参考图36,所述变形元件被显示为单个导电元件。 For example, with reference to FIG. 36, the deformable element is shown as a single conductive member. 可选地,可以通过例如在柔性电路之间使用绝缘材料构造所述变形元件,以便每个指状物(也显示为图30的元件5a),或其中的组合,提供分离和独立驱动的电路。 Alternatively, for example, by the use of insulating material between the flexible circuit structure of the deformable element, so that each finger (also shown as element 30 in FIG. 5a), or a combination of them, to provide separate and independent driving circuits .

[0262] 通过选择哪个电路给予控制电压,或提供多少控制信号,所述系统不但能够控制所述弯液面的形成和大小,也能够控制它的偏向。 [0262] By selecting which given control voltage circuit, or the number of the control signal, the system not only capable of controlling the formation and size of the meniscus, it is possible to control its deflection. 在本文中,偏向是指可以被用来配置所述半月板具有不同于轴对称垂直于所述边界元件和在所述流体腔室中央的形状的倾斜和偏移的可能组合。 As used herein, refers to bias can be used to configure the meniscus has a different axis of symmetry perpendicular to said inclined boundary element and possible combinations of the fluid chamber in the shape of the central and offset. 在图37中示出了简单实例,其中聚焦流体3b已经被进一步表示为半月板元件3c,显示为具有响应于多电路导体元件(未示出)的控制信号选择应用的非对称形状。 In FIG. 37 illustrates a simple example, wherein the focus fluid has been further indicated as 3b meniscus element 3c, is shown as having a selection control signal in response to the application of an asymmetrical shape (not shown) in the multi-conductor circuit element.

[0263] 导体元件被连接到被选来释放用于驱动所述变形元件贯穿它的整个预期移动范围所需要的电压范围和极性的电源。 [0263] is connected to the conductor elements is selected to release for driving said deformable element is expected to move throughout its entire range of the required power supply voltage range and polarity.

[0264] 可以引用附图以进一步为上述讨论提供背景上下文,应该理解为了这个讨论目的的方便,它们仅表示所述聚焦模块的特殊结构。 [0264] reference to the accompanying drawings may further provide a background context for the discussion above, it should be understood that for the purpose of discussion, they are only indicative of the focus of the special structure of the module.

[0265] 特别地,图29提供所述聚焦模块的一个实施例的分解图。 [0265] In particular, the focusing module 29 provides an exploded view of one embodiment. 在这个实施例中,隔离元件2在边界元件1和聚焦元件3之间建立了隔离关系。 In this embodiment, the spacer element 2 between the boundary element 1 and the focusing element 3 to establish a quarantine relationship. 压力元件4倚靠着聚焦元件3, 并且被变形元件5作用,其本身又被导体元件6作用。 The pressure element 4 leaning focusing element 3, and 5 are deformed effect element, which itself is a conductor element 6 role. 在显示的一个实施例中,导体元件6包括两个子元件6a和6b,它们是导电性元件,用来传输电控制信号给变形元件5。 In one embodiment shown, the conductor member 6 comprises two sub-elements 6a and 6b, which are conductive elements, the electrical control signal for transmission to the deformable element 5. 元件6c 是导体元件6的电接触端口。 Element 6c is a conductor element in electrical contact port 6. 在元件6a上具有附加电接触端口,但在图29中是不可见的。 With additional electrical contacts port on the element 6a, but FIG. 29 is not visible. 元件7是外壳元件,并且用于为所述聚焦模块提供物体环境。 Element 7 is a housing member, and for providing the environment for focusing the object module.

[0266] 图30 和31显示了图29的聚焦模块实施例的组装形式,其中外壳元件7、电接触元件6c、变形元件5和压力元件4都是大部分看得见的。 [0266] Figures 30 and 31 show the form of the focusing module assembly embodiment of FIG. 29, in which the housing member 7, the electrical contact member 6c, 4 and 5 are the most visible elements of deformable pressure element. 在图30的透视图,该组装好的聚焦模块是从图29的右侧看过去的,即所述边界元件最靠近看图者,而在图31中,该组装好的聚焦模块是从图29的左侧看过去的。 In the perspective view of Figure 30, which is assembled focusing module 29 is viewed from the right in the past, that the boundary element closest to the plug-person, but in FIG. 31, the focusing module is assembled from Figure Look past the left 29.

[0267] 该组装好的聚焦模块的整个尺寸不是严格的,并且可以根据可用部件的尺寸、它将被布置或组装进去的设备以及用户的需求而被改变。 [0267] the overall size of the assembled focusing module is not critical, and can be based on the size of available parts, it will be arranged or device and the user's needs into the assembly is changed. 总而言之,大体上如图30和31所示圆柱体的所述聚焦模块将具有从大约5、7、9mm到大约11、13、15或20mm—样大的直径d。 All in all, the focusing module 30 substantially as shown in Figure 31 and the cylinder will have from about 5,7,9mm to about 11, 13 or 20mm- diameter as large as d. 为了最大化或达到与已有设备的兼容性可以对其尺寸进行选择,例如在能照相的蜂窝电话中,优选大约9、9. 5、或IOmm的直径。 In order to maximize or achieve compatibility with existing devices can be selected for its size, e.g., in a cellular phone can be photographed, preferably about 9,9. 5, or IOmm diameter.

[0268] 为了示例之目的,图32和34每一个描述包括边界元件1、聚焦流体3b、聚焦薄膜3a、和变形元件5的组合。 [0268] For purposes of example, the boundary element 32 includes a focusing fluid 3b, focus film 3a, and a deformable element combination and a description of each 34 5. 在图32和34中,最小的压力被施加到聚焦流体3b上,而聚焦薄膜3a是相应平坦的。 In FIG. 32 and 34, the minimum pressure is applied to the focusing fluid 3b, and corresponding focus film 3a is flat. 在图33和35中,变形元件5施加压力到聚焦流体3b上,并且结果聚焦薄膜形成凸透镜或半月板。 In Fig. 33 and 35, the deformable element 5 focused on applying pressure to the fluid 3b, and the result is a film formed focusing lens or meniscus. 在图32中,变形元件5施加的力在充分垂直于聚焦薄膜3a所表示的平面的方向和边界元件1的方向上被施加,减小了包含所述聚焦流体的所述腔室在它圆周上的高度并且因此迫使流体从所述腔室的圆周流到中央;这个作用产生可从图33见到的凹半月板。 In Figure 32, the force exerted on the deformable element 5 sufficiently perpendicular to the focus direction and the boundary plane of the film element 3a in the direction indicated by 1 is applied, the reduced focusing fluid containing chamber in which the circumferential height and thus forcing the fluid to flow from the central chamber circumference; produce this effect seen from FIG. 33 concave meniscus.

[0269] 如前面注意到的,所述变形元件可以直接或间接地作用到所述聚焦流体上。 [0269] As previously noted, the deformable element may act directly or indirectly, to the focus on the fluid. 同样如前面指示的,直接作用可以包括布置所述变形元件直接连接到所述聚焦流体。 Also as previously indicated, it may include a direct effect of the deformable element is arranged directly connected to the focus fluid. 例如,直接接触所述聚焦薄膜,当所述聚焦元件包含聚焦薄膜和夹持在所述聚焦薄膜与所述边界元件之间的流体,具有定义为容纳所述聚焦流体的腔室的壁的隔离元件。 For example, direct contact with the film to focus when the focus of the focusing element comprises a thin film and a spacer sandwiched in the fluid film and the focus of the boundary between the element having focus is defined to receive the fluid chamber wall element. 在可选的实施例中,所述变形元件本身包括独立于所述边界元件和所述聚焦薄膜的所述壁。 In an alternative embodiment, the deformation element itself comprises independent of the boundary wall of the element and the focus of the film. 这样的实施例显示在图34中,其中变形元件5也作为限制聚焦流体3b的圆柱形腔室的壁使用,那个腔室具有由聚焦薄膜3a形成的“顶”壁和由边界元件1形成的“底”壁。 Such an embodiment is shown in Figure 34, wherein the deformable element 5 can also be construed as limiting the focusing cylindrical chamber wall 3b of the fluid used, the chamber has a thin film 3a is formed by a focusing "top" and is formed by the boundary wall element 1 "bottom" wall.

[0270] 在这个实施例中,被变形/隔离元件5施加的力是在充分平行于聚焦薄膜3a所表示的平面方向和在流体腔室中央的方向上被施加的。 [0270] In this embodiment, the deformation / force element spacer 5 is applied to the film in substantially parallel to the focusing plane direction indicated by 3a and the direction of the center of the fluid chamber is applied. 根据用于所述变形元件的材料特性, 这个压力不可以伴随有在所述流体腔室高度上的任何变化,并且所述变形元件可以简单地沿半径增大它的厚度。 According to the material properties of the deformable element, the pressure is not accompanied by any change in the height of the fluid chamber, and said deformable element may simply increase its radial thickness. 可选地,所述变形元件的沿半径向内延伸可以伴随有所述变形元件高度或厚度向内地减小,如图35所示,有效将聚焦薄膜3a和边界元件1挤向彼此并且有助于形成所述聚焦半月板,不仅是所述变形元件的向内沿半径地移动迫使所述聚焦流体填充更小直径的圆柱体,而且所述聚焦薄膜和边界元件的聚集也减小了圆柱体的高度。 Alternatively, the radially inwardly extending deformable element may be accompanied by the height or thickness of the deformable element decreases inwardly, shown in Figure 35, the film will focus on the effective boundary element 3a and pressed against each other and help 1 forming a meniscus at the focus, not only to move radially inwardly of said deformable element forces the focusing fluid-filled cylinder of smaller diameter, and the aggregation of the film and the boundary of the focusing elements is reduced cylinder height.

[0271] 更一般地,参考图38,所属聚焦模块可以包括具有至少一个上表面4101、下表面4102、外壁4103、流体内部体积4104的圆柱体4100,该圆柱体具有直径d和高度h。 [0271] More generally, with reference to FIG. 38, belongs to the focusing module may comprise at least one surface 4101 and lower surface 4102, outer walls 4103, 4104 of the volume of the fluid inside the cylinder 4100, the cylinder having a diameter d and height h. 当所述驱动元件在这个结构的外部时,为了使高度h和直径d的一个或全部减小,它将施加压力在上表面、下表面、或外壁的至少一个上。 When the outer element of this structure, in order to make a height h and diameter d or all reduced, it will exert pressure on the driving at least one upper surface, a lower surface, or the outer wall. 因为该流体内部体积的容量是不能压缩的,这种在高度和/或直径的减小必须由在某个方向上体积的相应扩张来进行补偿,在所述聚焦模块的情况下,其将引起上表面4101和下表面4102的一个或全部的变形。 Because the internal volume of the fluid volume is incompressible, that the height and / or reducing the diameter must be in a certain direction by the volume of the corresponding expansion to compensate, in the case of the focusing module, which will cause 4101 upper surface and a lower surface of one or all of the deformation of 4102. 图39和40提供了这种效果的简明的垂直侧面视图。 Figures 39 and 40 provides a concise this effect vertical side view. 尤其图39提供高度减小导致变形的视图,现在该圆柱体具有相同的直径d,但是高度IT <h。 In particular, Figure 39 provides a high degree of deformation leads to reduced view, now the cylinder having the same diameter d, but the height IT <h. 而图40提供直径减小导致变形的视图,现在该圆柱体具有相同的高度h,但是直径cf <d。 And Figure 40 provides a view of the reduced diameter leading to deformation of the cylinder now has the same height h, but the diameter cf <d. 这两个视图都不需要按比例的。 These two views are not required to scale. 如果由上表面4101的凸起变形来补偿的话,在这些当中都阐述了在一个方向上的相应变形和改变。 If the deformation of the upper surface of the projection 4101 to compensate for it, which are set forth in the corresponding modifications and variations in one direction. 在这些实施例中,所述变形或驱动元件可以施加压力到如图29-35所示的内部流体上。 In these embodiments, the drive element may be deformed or the internal fluid pressure is applied to 29-35 as shown in Fig. 当然,所述直径和所述高度二者都可以同时被改变,并且这样可以被用来产生相对大的半月形,和/ 或减少形成该半月形所需的时间。 Of course, both the diameter and the height can be changed at the same time, and thus can be used to generate relatively large half-moon, and / or reduce the time required for the formation of the meniscus.

[0272] 可选地,所述变形或驱动元件可以包括外壁4103的部分或全部,如图41和42所示的。 [0272] Optionally, the drive element may deform or include part or all of an outer wall 4103, shown in FIG. 41 and 42. 这里该圆柱体被显示为截面图以阐述变形元件5的环形状态。 The cylinder is shown here as a sectional view to illustrate the state of deformation of the annular element 5. 在图41中,上可变形表面(未示出)将是平的,而在图42中所述变形元件已经通过在垂直或“h”方向压缩以及在水平或“d”方向延伸或拉长对驱动作出了响应。 In Figure 41, the upper deformable surface (not shown) will be flat, while in FIG. 42 in the deformable element has passed in the vertical direction or the "h" compression and extension in a horizontal or "d" direction or stretched driving responded. 在图42中,通过所述变形元件将上及下表面同样一起地画在它们的整个表面区域上来显示出效果,其要求一个或二者的外圆周是垂直可移动的或滑动的而不是固定的或锚定的。 In Figure 42, the deformable element through the upper and lower surfaces of the same to draw together in their entire surface region shows up effect, which require one or both of the outer circumference of the vertically movable instead of fixed or sliding or anchored. (在这个讨论中,方向参考例如“水平的”、 “垂直的”等等一般是被用在相对而不是绝对的感觉上,例如,关于垂直参考由垂直于都是平面的上和下表面的直线所定义的方向,而水平参考由平行于都是平面的上和下表面的直线所定义的方向)。 (In this discussion, the direction of reference such as "horizontal" and "vertical" and the like are generally used on the relative rather than absolute sense, for example, with respect to the vertical reference is made perpendicular to the plane and a lower surface direction defined by a straight line, parallel to the horizontal reference direction and the lower surface is a straight line on a plane defined above). 然而,也可以预期至少一个表面或表面边缘将是固定的或锚定的,当所述变形元件改变它的大小时,其将导致不同的效果。 However, we can expect that at least one surface or edge will be fixed or anchored, when the deformable element to change its size, which would lead to different results. 例如,通过参考图42,如果上表面是可变形的而下表面是不变的,并且该圆柱体的外圆周而被限制,例如被包含在金属、陶瓷或其他刚性材料的环内,那么所述变形材料在垂直方向上收缩或压缩以及在水平方向上延伸或拉长的移动将不会是均勻和对称的,而是将导致例如图43所示的象漏斗形的。 For example, with reference to FIG. 42, if the surface is deformable and the lower surface is constant, and the outer circumference of the cylinder is restricted, for example, is contained within a metal ring, ceramics or other rigid material, so that moving said deformable material shrinkage or compressed in the vertical direction as well as extended or elongated in the horizontal direction will not be uniform and symmetrical, but will lead to, for example, as shown in FIG. 43 of the funnel of.

[0273] 应该注意到,构造所述聚焦模块来生成凹透镜也是同样可能的。 [0273] It should be noted, the focusing module configured to generate a concave lens is also possible. 例如,所述压力环和变形元件可以被定位在所述聚焦薄膜下、在那个薄膜和所述隔离元件之间,并且所述变形元件的激活可以增大而不是减小所述流体腔室在它圆周周围或外周的高度。 For example, the pressure ring and the deformable element can be positioned at the focus film, between the film and the spacer element, and the activation of the deformable element can be increased rather than reduced in the fluid chamber It circumference or the outer circumference of the height. 如果所述变形元件也作为所述隔离元件使用,那么将达到同样的效果。 It is also used as the spacer element if the deformable element, it will achieve the same effect. 所述压力元件不一定要存在,其这种情况下所述变形元件将直接作用在所述聚焦薄膜上。 The pressure element does not have to exist, under which the case deformation element acts directly on the film focusing.

[0274] 可以参考关于准备和填充所述流体腔室的特定方法另一个凹透镜的实例。 [0274] refer to the specific method of preparing for, and the fluid chamber filled with another concave lens instance. 第一, 将一个或多个边界元件,例如玻璃板,放置在位于例如金属板的支撑结构内的凹部内。 First, one or more boundary elements, e.g., a glass plate, is placed in the recess located e.g. metal plate supporting structure. 第二,将PDMS薄膜或层放置在所述玻璃板隔离元件组合上,可以例如通过利用已知技术将所述PDMS旋转地涂到期望的厚度来准备所述薄膜。 Second, the PDMS layer is placed on the film or the glass spacer element combinations, for example, by using known techniques applied to the PDMS rotatably desired thickness to prepare the film. 接着将玻璃板边界元件、隔离元件、和PDMS薄膜元件的最终组合放置在真空下,加入聚焦流体,并且释放所述真空以便将所述聚焦流体吸进所述流体腔室。 Next, the glass plate border element isolation member, and the final composition PDMS membrane element is placed under vacuum, was added focus fluid, and releasing the vacuum to draw fluid into the focus of the fluid chamber. 如果在所述流体腔室完全被填满之前停止这个填充过程,所述聚焦薄膜的最初形状将是凹的。 If you stop the filling process before the fluid chamber is completely filled, the original shape will be the focus of the film is concave. 根据所选择的凹陷的程度和为所述聚焦模块的剩余容量所选的参数,所述最终模块可以仅通过改变所述聚焦元件的凹陷程度而起作用,或者可以能够使所述薄膜从凹陷状态变形到平坦状态,并且甚至使它变形超过平坦状态到凸状态。 According to the degree of depression of the selected parameters and the remaining capacity of the selected focusing module, the module may ultimately only by changing the degree of focusing recess element which functions, or may be able to make the film from the recessed state deformation to the flat state, and even deform it over a flat state to state projections.

[0275] 根据控制信号是否被施加,所述变形元件具有激活和不激活状态,并且在这两个状态之间具有连续的过渡,优选地是线性地响应于控制信号的长度。 [0275] Depending on whether the control signal is applied, the deformation element having activated and non-activated state, and between these two states having a continuous transition, preferably linearly in response to a control signal length. 用“使无效”来描述当控制信号是零或最小输入时所述变形元件的状态,而用“激活”来描述当控制信号被应用时所述变形元件的状态,可以将该系统配置为其中之一以便所述使无效是正在应用最大的力到所述聚焦元件的时候,或正在应用最小的力的时候。 With "invalidate" to describe when the control signal is a state of the deformable element to zero or minimum input, and with the "active" to describe the state of the deformable element when the control signal is applied, the system can be configured to one in order to invalidate one of the largest force is being applied to the time of the focusing element, or a minimum of force being applied when. [0276] 因此,可以将图32和34称为表示使无效状态,配置该系统以便当没有正在使用控制信号时,所述变形元件传输最小的力给所述聚焦流体。 [0276] Therefore, it can be called 32 and 34 represent invalidate state, configure the system so that when there is no control signal is in use, said deformable element minimum force transmitted to the focusing fluid. 而图33和35可以表示激活状态, 其中控制信号正被应用来激励所述变形元件。 The 33 and 35 may represent an active state in which the control signal being applied to excite the deformable element. 然而,相反地配置该系统也是可能的,以便图32和34表示当所述控制信号正被应用时该系统的状态,而图33和35表示当所述控制信号是零或最小强度时它的状态。 However, the contrary is also possible to configure the system so that 32 and 34 shows a state when the control signal being applied to the system, while 33 and 35 indicate when the control signal is zero or minimum intensity when its state. 更明确地,所述变形元件可以是当电源关断时被释放(如在图32和34中)或当电源关断时被拉长或被扩张(如在图33和35中),反之而然。 More specifically, the deformable element may be turned off when the power supply is released (see Figure 32 and 34) or when the power is turned off is elongated or expansion (as in Figures 33 and 35), and vice versa However. 这大体上转化为所述聚焦模块的期望“静止”状态应该处于的状态。 This is generally converted into the desired focus module "stationary" state should be in the state. 当所述聚焦薄膜是平坦的时, 所述聚焦被设置为无限远,而当它是凹的,所述聚焦是在有限的距离,例如从大约5mm到大约500mm,包括他们之间的所有的点,例如大约50、100、150或200mm。 When the film is flat when the focus, the focus is set to infinity, and when it is concave, the focus is limited distance, e.g., from about 5mm to about 500mm, including between them all the point, for example, about 50, 100 or 200mm. 因此配置所述系统的这个状态可以根据用户是否希望“正常”或“静止”状态被聚焦在无限远,或更近。 So the configuration of the system in this state can be focused at infinity, or more recently based on whether the user wants a "normal" or "resting" state.

[0277] 当已经将前面的讨论呈现为聚焦元件包括聚焦流体和聚焦薄膜的情况下,其也是适用于在所述聚焦元件是整体的情况下的可选实施例,如在填满流体/填满油的弹性体的情况下。 [0277] when the preceding discussion has presented to the focusing element includes focusing a fluid film and the focus situation, which is adapted to the focusing element is an alternative embodiment of the entire case, as in the fill fluid / fill if the elastic body full of oil under. 在这个实施例中,所述聚焦弹性体的外表面提供所述聚焦薄膜的功能,所述聚焦弹性体的内表面提供所述聚焦流体的功能。 In this embodiment, the focusing of the outer surface of the elastomeric film provides the function of the focus, the focus of the inner surface of the elastic body fluid providing the focus function.

[0278] 所述变形元件和本发明的相关组合也可以被用来控制常规的移动,而不仅仅是流体,透镜。 [0278] The deformable element and associated compositions of the present invention can also be used to control the movement of a conventional, rather than the fluid lens. 进一步可能将本发明的所述聚焦模块和一个或多个常规或流体/适应性透镜、 和/或一个或多个其他聚焦模块组合。 It is further possible to the focus module of the present invention and one or more conventional or fluid / adaptive lenses, and / or other combinations of one or more of the focus module. 以这样的方式,可以实现例如变焦和自动变焦等其他功能。 In this way, you can achieve other functions such as zoom and automatic zoom and so on. 这些和相关概念被进一步描述在与本揭露同时编列的附录中。 These and related concepts are further described in the present while exposing provision of the appendix.

[0287] 通过操作透镜配置可以实现激光条形码扫描仪。 [0287] lens configuration can be achieved by operating the laser bar code scanner. 参见下文图86-88。 See below Figure 86-88. 不使用目前在条形码扫描仪中使用扫描镜子或马达,可以使用易操作的流体透镜来实现该扫描移动。 Do not use the current motor using a scanning mirror or barcode scanner can be operated using a fluid lens is easy to achieve the scanning movement. 在相同时间最窄光束宽度的激光点位置会由于相同或不同流体透镜而被影响。 The position of the laser spot at the same time the narrowest width of the beam due to the same or different fluid lens is affected. 这个扫描系统实质上也可以是共轴的,在那里接收和发送光束都聚焦在将被扫描的所述条形码图案的相同部分。 The scanning system may be substantially coaxial, where the receive and transmit beams are focused on the same section of the bar code to be scanned pattern. 这个接收光系统没有显示出来,但在现有技术中这些都是公知的。 The received light system does not show up, but in the prior art which are well known. 圆柱形或球形流体透镜可以被使用,取决于设计者期望是开发单扫描线还是光栅扫描线。 Cylindrical or spherical fluid lens may be used, depending on the designer is desirable to develop a single scan line or raster scan lines. 也可以预想, 开发仅能扫描而没有光学放大率的流体透镜也是可能的。 It can also be expected to develop not only the optical scanning magnification lens fluid is also possible. 这样的系统也是加以预期的。 Such a system is also to be expected.

[0288] 如可以从图53见到的,本发明的阅读器能够操作的距离,或相同的,所述阅读器的光系统焦距可以变化,如从所述透镜到将被成像物体的距离q变化。 [0288] As can be seen from FIG. 53, the present invention is capable of operating from the reader, or the same, the focal length of the optical reader system can vary, as from the lens to the object to be imaged from the q change. [0289] 对于特殊几何位置的焦距可以通过这个方程式确定: [0289] For the particular geometry of the focal length can be determined by the equation:

[0290] 1/f = l/p+1/q [0290] 1 / f = l / p + 1 / q

[0291] 其中f是透镜焦距,ρ是从所述透镜到在其上观察到期望的图像的表面(例如成像传感器或光学胶片)的距离,而q是所述透镜与被观察物体之间的距离。 [0291] where f is the focal length, ρ from the lens to the surface on which a desired image is observed (e.g., optical imaging sensor or film) distance, and q is the lens and the object to be observed between distance.

[0292] 考虑位于离所述阅读器透镜更近距离ql和更远距离q2的两个物体(例如q2 > ql)。 [0292] consider from the reader lens located closer ql and q2 of two more distant objects (such as q2> ql). 在不昂贵并且很常规构造的系统中,距离P (从透镜920到成像传感器922)是固定的。 Not expensive and very conventional in structure system, the distance P (from the lens to the imaging sensor 920 922) is fixed. 具有给定的焦距l/fl = l/p+l/ql,我们可以在位于离所述透镜的距离ql对物体进行成像, 我们可以在位于离所述透镜的距离q2对物体进行成像,焦距给出为l/f2 = l/p+l/q2。 Having a given focal length l / fl = l / p + l / ql, we can located a distance from the lens ql imaging of objects, we can located at a distance from the lens to the object q2 imaging, focal length It is given by l / f2 = l / p + l / q2. 因为q2 > ql,而且ρ是常数,所以我们得出fl < f2。 Because q2> ql, and ρ is a constant, so we have come to fl <f2. 特别地,对于包含能够在固定值ρ情况下提供最小焦距Π和最大焦距f2的流体透镜的阅读器,我们将能够在至少从ql到q2距离范围内正确地观察聚焦物体,而不用考虑例如在所述透镜的特别焦距设置时的场域深度的问题。 In particular, the contained value can be provided at a fixed focal length Π ρ minimal and maximum focal length f2 of the fluid lens of the reader, at least we will be able to correctly observe from ql q2 distance within the range of focus object, regardless example, depth of field problems, especially the focal length of the lens when set. 作为实例,ql可以是短距离的,例如4英寸(接近IOcm)以便我们可以通过存在于物体上的所有细节转换或解码而对具有更多细节的目标物体(例如高密度条形码)进行成像。 As an example, ql may be a short distance, e.g., 4 inches (nearly IOcm) so that we can be present on all the details of an object and for converting or decoding target object with more detail (e.g. high-density bar code) imaging. 另一方面,q2可以是较长距离的,例如12英寸(接近30cm)或更多,从而阅读器可以在更长的距离对有更低密度(例如,在所述目标物体上的每单元长度或区域更低的像素分辨率)的物体进行成像。 On the other hand, q2 may be a long distance, for example 12 inches (approximately 30cm) or more, so that the reader may have a longer distance to the lower density (e.g., on the target object per unit length or region lower pixel resolution) for imaging an object. 相应的,可以将包括特别成像传感器的本发明阅读器配置为执行极其高密度/短距离或极其低密度/长距离之一(或对这两个极限值而言任意可变的中间情况),通过简单有利的所述流体透镜的焦距控制,以便在q2 > d > ql范围的预期距离d的物体将被正确成像。 Accordingly, you can include a special image sensor of the present invention, the reader is configured to perform extremely high density / short or extremely low density / one long-distance (or these two extremes in terms of any variable in the middle), the focus control by simply enabling the fluid lens, so that q2> d> ql range of object distance d expect will be properly imaged.

[0293] 可以导致所述透镜手动地或自动地改变它的焦距直到为在一给定距离远的物体实现最佳聚焦。 [0293] can cause the lens manually or automatically changes its focal length until the object is at a given distance of optimum focus. 执行这个的一种方法是使由点或视场内的物体形成的所谓弥散圆最小化。 One way to do this is to make the so-called circle of confusion from the point or the field of view of the object is formed is minimized. 这可以被微处理器自动地执行,其改变所述透镜的焦距并且测量在CCD或CMOS成像器上所述弥散圆的尺寸,即所述弥散圆装满的像素数量。 This can be performed automatically by the microprocessor, which changes the focal length of the lens and measured on a CCD or CMOS imager size of the circle of confusion, i.e., the number of pixels of the full circle dispersion. 在所述弥散圆最小时的焦距是最佳聚焦并且透镜被保持在那个位置。 In the circle of confusion of the hour is the best focus and focal length lens is held in that position. 如果在视场内的某些东西变化,例如所述物体变得离所述透镜更远,那么所述微处理器将检测所述弥散圆的变化和尺寸,并且控制自动聚焦程序。 If you change something in the field of view, such as the object becomes farther away from the lens, then the microprocessor will detect the change and the size of the circle of confusion, and control the Auto Focus.

[0294] 被用来测量所述弥散圆的所述物体可以是在视场内固有的细节,或者它可以是在视场内有层次的物体。 [0294] The object is used to measure the circle of confusion in the field of view may be inherent in detail, or it may be within the field of hierarchical objects. 作为实例,我们可以投射IR激光点到场内(该IR的波长是超过了人眼睛的敏感度,但不超过CCD或CMOS的敏感度)。 As an example, we can point to the projected IR laser field (the IR wavelengths than the human eye is sensitive, but not exceeding sensitivity CCD or CMOS). 完成最佳聚焦的另一种方法包括将所述图像变换到频域,例如用傅立叶变换,并且随后调节所述流体透镜的焦距以使得将转换图像的高频部分结果最小化。 Another way to do the best focus image comprising transformed to the frequency domain, e.g., by Fourier transform, and then adjusting the focal length of the lens so that the fluid results converts the high frequency portion of the image is minimized. 可以以相似的形式使用所述图像的小波变换。 The image can be used in a similar form wavelet transform. 频率变换或小波技术都是为通过最大化在CCD或CMOS图像传感器的像素之中的对比度而完成最佳聚焦的简单技术。 Frequency or wavelet transform technique is to maximize contrast by pixel CCD or CMOS image sensor among the best focus and complete a simple technique. 这些以及相似处理,例如最大化邻近像素之间的强度差,是本领域公知的并且也是普遍被使用在数字照相机的被动聚焦中。 These and similar processing, such as to maximize the intensity difference between adjacent pixels, are known in the art and is commonly used in digital cameras in a passive focusing.

[0295] 图55是表示用于本发明的各种实施例的通用微处理器系统的光学阅读器的方框图。 [0295] FIG. 55 is a block diagram of the optical reader used in various embodiments of the present invention, the general purpose microprocessor system. 光学阅读器4010包括用来照亮目标物体T,例如ID和2D条形码符号,的照明组合4020 ; 和用来接收物体T的图像并产生在其中表示光学编码数据的电输出信号的成像组合4030 ; 照明组合4020可以包括,例如,照明光源组合4022,与例如一个或多个透镜、扩散体、楔块、 反射镜或这些元件的组合的照明光学组合4024 —起从光源4022向目标物体T的方向引导光线。 The optical reader 4010 includes means for illuminating the target object T, such as ID and 2D bar code symbol, a combination of illumination 4020; and means for receiving the object T and generating an image in which the electrical output signal represents the combination of the imaging optical code data 4030; Lighting 4020 can include a combination of, for example, a combination of illumination light source 4022, for example, one or more lenses, a combination of the illumination optical diffusion member, wedges, reflectors or combinations of these elements 4024-- direction starting from the light source 4022 to a target object T, guiding light. 照明组合4020可以包括,例如,激光或发光二极管(LED),例如白色LED或红色LED。 Lighting 4020 can include a combination of, for example, a laser or a light emitting diode (LED), for example, a white LED or red LED. 照明组合4020可以包括目标照明和用来突出在物体T上的瞄准图案4027的光学对准。 Lighting combinations may include target illumination and 4020 to highlight the object on the aiming pattern T 4027 optical alignment. 如果确定周围光的级别是足够高的并允许获得物体T的高质量图像,那么照明组合4020也可以去除。 If it is determined that the level of ambient light and allows to obtain a sufficiently high quality image object T, then the lighting combination 4020 may be removed. 成像组合4030可以包括图像传感器4032,例如ID或2D⑶D、CMOS、NMOS、PMOS、 CID或CMD固态图像传感器,与成像光学组合1034 —起用来在图像传感器4032上接收和聚焦物体T的图像。 4030 imaging composition can include an image sensor 4032, such as ID or 2D⑶D, CMOS, NMOS, PMOS, CID or CMD solid state image sensor, in combination with the imaging optical 1034-- play on the image sensor 4032 for receiving and focusing an object image T.

[0297] 利用能够被控制模块发送命令来输出图像数据的局部帧、或能够被与独立编址的像素一起配置的图像传感器,容易实现局部帧时钟输出模式。 [0297] The use of commands that can be sent to the output control module partial frame of image data, or an image sensor with a pixel can be addressed independently arranged together, easy to implement local frame clock output mode. 利用CMOS制造技术,容易制造图像传感器以便相应于传感器的某些像素的电信号能够被选择性地输出,而不输出相应于该传感器的剩余像素的电信号,因此允许仅对仅与整个图像视场的一部分关联的局部数据帧进行分析。 Utilizing CMOS fabrication techniques, image sensors in order to be easily produced electrical signals corresponding to certain pixels of a sensor can be selectively output without the output of the sensor corresponding to the remaining pixels of the electrical signal, thus allowing only the entire image, as the only part of the local data field associated analysis frames. CMOS图像传感器可以从这些制造商获得,例如Symagery、Omni、Vision,夏普,Micron,ST微电子、柯达、东芝和三菱。 CMOS image sensors can be obtained from the manufacturer, for example Symagery, Omni, Vision, Sharp, Micron, ST Microelectronics, Kodak, Toshiba and Mitsubishi. 通过在从C⑶图像传感器输出图像数据帧期间选择性地激活帧放电信号,也可以实现局部帧时钟输出模式。 By selectively activating the image output from the image sensor C⑶ data frame discharge signal frame period, it can achieve a partial frame clock output mode. A/D1036和信号处理器1035 可以单独地或可选地都被和图像传感器1032 —起集成在单个的感光底层上。 A / D1036 and signal processor 1035 can be used alone or alternatively are and the image sensor 1032-- from integrated on a single photosensitive layer.

[0298] 图55的光学阅读器也包括可编程控制电路(或控制模块)1040,其优选地包括集成电路微处理器4042和专用集成电路(ASIC 4044)。 [0298] FIG. 55 is an optical reader also includes a programmable control circuit (or control module) 1040, which preferably includes a microprocessor 4042 and ASIC integrated circuits (ASIC 4044). ASIC 4044的功能也可以由场可编程逻辑阵列(FPGA)提供。 ASIC 4044 functions to be provided by the field-programmable logic array (FPGA). 处理器4042和ASIC 4044都是可编程控制装置,其能够根据存储在存储器单元4045的被存储程序接收、输出和处理数据,存储器单元4045可以包括存储元件例如读/写随机存取存储器或RAM4046和可擦除只读存储器或EROM 4047。 Processor ASIC 4044 and 4042 are programmable control means, which is capable of storing the received program is stored in the memory unit 4045 in accordance with the output data and the processing, memory unit 4045 may include a storage device such as a read / write or random access memory RAM4046 and erasable read-only memory or EROM 4047. 其他可以被使用的存储器单元包括EPROM和EEPR0M。 Other memory cells can be used include EPROM and EEPR0M. RAM 4046典型地包括至少一个易失性存储装置, 但也可以包括一个或多个长期非易失性存储装置。 RAM 4046 typically includes at least one volatile memory device, but may also include one or more long-term non-volatile storage means. 处理器4042和ASIC 4044都被连接到公共总线4048,通过该总线可以双向地对任何也被连接到其中的电路接收和发送程序数据和运行数据,包括地址数据。 Processor ASIC 4044 and 4042 are connected to a common bus 4048, via the bus can also be bi-directionally connected to any circuit which receive and transmit program data and operating data, including the address data. 然而,处理器4042和ASIC 4044彼此的不同在于它们是怎样被制造和它们怎样被使用。 However, the processor 4042 and ASIC 4044 is different from each other that how they are manufactured and how they are used. 处理模块被配置来抽取由编码符号编码的信息,其使用处理器4042和ASIC 4044容量的一些或全部,并且包括必要硬件、软件和或固件,其是实现该抽取任务所需要的,抽取任务包括将图像的原始数据转换为用编码符号编码的信息的必要解码任务。 The processing module is configured to extract the information encoded by the encoding symbols, using some or all of 4042 and the ASIC 4044 processor capacity, and includes the necessary hardware, software, and or firmware, which is to achieve the desired extraction task to extract tasks include The raw image data into coded symbols encoded with the information necessary to decode tasks.

[0299] 更具体地处理器4042最好是通用的、现货供应的VLSI集成电路微处理器,其具有图55的电路的整体控制,但其花费它的大部分时间来解码存储在RAM4046中的图像数据和存储在EROM 4047中的程序数据。 [0299] More specifically, is the best general-purpose processor 4042, VLSI integrated circuit microprocessor shelf, which has overall control of the circuit in Fig. 55, but spend most of its time to decode the stored RAM4046 program data and image data stored in the EROM 4047. 另一方面,ASIC 4044最好是专用的VLSI集成电路, 例如可编程逻辑阵列或门阵列,其被编程为将其时间用来进行功能运行而不是解码图像数据,并因此使处理器4042从执行这些功能运行的负担中释放出来。 On the other hand, ASIC 4044 is preferably a dedicated VLSI integrated circuit, such as a programmable logic array or gate array, which is programmed to carry out its function of time and not run the decoded image data, and thus the processor 4042 from the execution These functions running load release.

[0300] 处理器4042和ASIC 4044之间的实际工作分工将自然地依赖于可获得的现货供应微处理器的类型、使用的图像传感器的类型、图像数据被成像组合4030输出的速率,等等。 [0300] ASIC processor 4042 and 4044 between the actual division of work will naturally depend on the type of available shelf microprocessor, the type of image sensor used, the image data is imaged combined 4030 output rate, etc. . 然而,在处理器4042和4044之间的工作分工,或者甚至根本上进行这样的分工,原则上是没有任何要求的。 However, the division of labor between the processor 4042 and 4044, or even make such a fundamental division of labor, in principle, there is no requirement. 这是因为如果通用处理器4042是足够快的并且做有能力执行本发明预期的所有功能,那么专用处理器4044可以被完全地去除。 This is because if a general purpose processor 4042 is fast enough and do have the ability to perform all the functions expected of the present invention, then a dedicated processor 4044 can be completely removed. 因此可以理解,所用处理器的数量和它们之间工作的分工都不在本发明目的基本重要性之中。 So you can understand, the use of the number of processors and the division of work between them are not in the object of the present invention being of fundamental importance.

[0301] 使用图55所示类型的处理器架构,处理器4042和4044之间的典型工作分工如下所述。 Of the type shown 55 [0301] Using FIG processor architecture, typical division of labor between processor 4042 and 4044 are described below. 处理器4042优选地主要专注于这样的任务,例如解码图像数据,这些数据已经被存储在RAM 4046中;根据光学符号识别(OCR)原理识别在被存储的图像数据中表示的字符; 处理菜单选择和再编程功能;处理从控制/数据输入单元1039接收的命令和数据,控制/ 数据输入单元1039可以包括象触发器1074和键盘1078这样的元件;以及提供整个系统级的协调。 Processor 4042 preferably primarily focused on such tasks, such as decoded image data that has been stored in the RAM 4046; the character based on optical character recognition (OCR) principles identified in the image data is stored in the representation; processing menu selection and re-programming; process from the control / data input unit 1039 receives commands and data, control / data input unit 1039 may include a keyboard 1078 and 1074 as a trigger such elements; and providing a level of coordination across the system.

[0303] 图56是表示用来操作具有包括反馈的可调聚焦系统的系统的处理的流程图1100,例如具有如在图53中所描述的部件的系统。 [0303] FIG. 56 is a flowchart 1100 for operating the process with adjustable focusing system includes a feedback system, such as system 53 having components as described in the. 该处理从步骤1110开始,其中产生捕捉图像的命令,例如通过用户按压触发器、或通过自动系统响应于特殊情况而发出捕捉图像命令,例如被感应的物体进入到成像位置。 The process starts at step 1110, where a capture image command, for example by the user pressing the trigger, or in special circumstances to issue a command to capture an image through an automated system response, such as the sensed object into the imaging position. 一旦在步骤1110捕捉到图像,图像聚焦被评估, 如步骤1120指示的。 1110 captured image, the image focus is evaluated once in steps, such as indicated in step 1120. 聚焦评估可以包括将图像质量与特殊标准或情况进行比较,例如在图像中的特征感觉边缘对比度的锐度,或其他标准。 Focus evaluation may include standard or special image quality were compared, for example, in the sense of edge features in the image contrast sharpness, or other criteria.

[0304] 另一种利用平面度量执行自动聚焦操作的处理过程包括下面的步骤: [0304] Another measure of the automatic focusing operation plane processing comprises utilizing the following steps:

[0305] 1、捕捉灰度比例图像(也就是用手持阅读器捕捉图像并且用至少2位分辨率、或至少4个离散值数字化该图像); [0305] 1, to capture gray scale image (ie, handheld readers to capture an image and resolution with at least two, or at least four discrete values of the digitized images);

[0306] 2、可选地采样该灰度比例图像(也就是从该图像中抽取一条线或一系列点,或可选地,如果它是包括相应于选择的编址像素的图像数据的被窗口化帧,那么被采样的图象就是被捕捉的图像); [0306] 2, alternatively sampling of the gray scale image (that is extracted from a line or a series of points in the image, or alternatively, if it includes the image data corresponding to the selected pixels are addressed windowed frame, then the sampled image is an image to be captured);

[0307] 3、通过描绘具有特殊灰度比例值的数据点事件的测量数目来创建柱状图,例如用X轴表示灰度比例值,而Y轴表示事件频率; [0307] 3, the number of measurements is depicted by the gray scale value of particular event data points to create a histogram, e.g., X-axis represents the gray scale value, and the Y axis represents the frequency of the event;

[0308] 4、处理该柱状图以提供平面测量作为输出; [0308] 4, the histogram processing to provide a flat measured as output;

[0309] 5、基于该平面测量确定聚焦级别(或聚焦质量);以及 [0309] 5, based on the plane measurements to determine the focus level (or focus quality); and

[0310] 6、在从该平面度量确定的聚焦质量小于预期时,改变聚焦并重复步骤1-5。 [0310] 6, when the focus quality metric determines the plane is less than expected, changing the focus and repeat steps 1-5.

[0311] 图像的所述平面是指在柱状中不同灰度级值分布的均衡度。 [0311] The plane image refers to the inequality in different gray level value column in distribution. 平面分布是在不同灰度级值的许多观察值具有很小变化。 Plane is a small change in the distribution of observed values in many different gray level values. 通常,聚焦差的图像将比聚焦好的图像更平坦,也就是说,将在整个灰度级值的范围内具有灰度级值相对平均的发生率。 Typically, the difference image is focused flatter than focusing good image, that is, having a relatively average gradation value in the range of incidence of the entire gradation value. 大体上,对于良好聚焦的图像的柱状图具有许多灰度级值高的像素、许多灰度级值低的像素、和许多灰度级值在中间的像素。 In general, for a well-focused image histogram having a plurality of pixel gray level value is high, a lot of low gradation pixel values, and a number of gray scale values of pixels in the middle. 对于各种类型图像历史信息的使用,例如条形码,包括根据查找表编码的信息, 或利用模糊逻辑原理提供的信息,是可预期的。 For all types of image history information, such as bar codes, including the information encoded according to a lookup table, or the use of fuzzy logic principle to provide information, it is to be expected.

[0312] 在步骤1130中,将所述聚焦评估的输出与可接受的标准进行比较,例如在特定数量像素上的特定数量清晰度(或对比度变化)。 [0312] In step 1130, the evaluation of the focused output with an acceptable standard for comparison, e.g., a specific number on a specific definition of the number of pixels (or contrast changes). 被数字化为更高数字分辨率(例如,使用由更大数据位定义的范围)的图像可以支持可接受聚焦的更精确的判断。 Digitized into higher digital resolution (for example, using the range defined by the larger data bits) can support an acceptable image focus more accurate judgments. 如果聚焦评估的结果是否定的,程序处理到步骤1140,在那里图53的透镜920的聚焦被修改。 If the focus evaluation result is negative, the processing procedure to step 1140, where the focusing lens 53 in FIG. 920 is modified. 在调整所述聚焦之后,程序的操作返回到步骤1110,并且捕获一个新的图像,接着评估。 After adjusting the focus, the procedure returns to step 1110, and capture a new image, followed by assessment. 当发现捕获的图像具有合适的聚焦,程序从步骤1130移到步骤1150,其中处理具有合适聚焦特性的图像, 并且得到用户或发布命令捕捉图像的仪器可以获得的结果,和/或将该结果存储在存储器中。 It was found that when a captured image having an appropriate focus, the program moves to step 1150 from step 1130, in which the processing image with proper focusing characteristics, and to give the user or issue orders to capture an image of the instrument can be obtained and / or the results are stored in memory. 可选地,如步骤1160所指示的,可以命令系统获得另一个图像然后返回到步骤1并且再次重复这个处理程序。 Alternatively, as indicated in step 1160, the system can command another image obtained then returns to step 1 and repeats this process again.

[0313] 图57是表示用来操作具有不包含反馈的可调聚焦系统的系统的程序流程图。 [0313] FIG. 57 is a diagram used to operate with non-adjustable focusing system comprises a feedback system program flow chart. 在步骤4210产生捕获图像的命令,例如通过用户按压触发器,或通过系统响应于特定条件自动地发布图像捕捉命令,例如感应到物体进入用以成像的位置。 4210 captured image generated command in step, for example by the user pressing the trigger, or automatically by the system in response to specific conditions published image capture command, such as induction into the objects into position for imaging. 在步骤4215中,用相应于第一条件,例如默认条件,的第一流体透镜控制信号驱动透镜920,例如使用被用在透镜920上致使透镜920以靠近聚焦位置7英寸的ql来操作的电压。 In step 4215, the first with the corresponding conditions, e.g., default conditions, first fluid lens control signal drives the lens 920, for example, be used on the lens so that the lens 920 to a voltage near the focus position of the 7-inch 920 operated ql . 在优选实施例中,离焦点7英寸的应用电压是0伏特。 In a preferred embodiment, the focus of seven inches from the application of voltage is 0 volts. 利用这种聚焦条件,在步骤4220捕获和处理一个图像。 With this focus condition, an image capture and processing in step 4220. 在步骤4225,检查从捕获的图像重新找回的信息以确定是否已经获得条形码的有效解码。 In step 4225, check from the captured image to retrieve the information to determine whether an effective decoded barcode. 如果解码是有效的,在步骤4260对报告的由被解码图像表示的信息和数据进行显示,并且程序停止,如步骤4270指示的。 If the decoding is effective, information and data reported by the step 4260 pairs decoded image representation in the display, and the program is stopped, as indicated in step 4270. 可以给出用来重复该程序的随后命令,当或许是需要的或有利的。 It can be given to repeat the subsequent command of the program, when perhaps needed or advantageous.

[0314] 如果在步骤4225确定了没有达到良好的解码,程序继续到步骤4230,在那里将被应用到透镜920的所述流体透镜控制信号调节到第一可选值,例如导致透镜920以靠近聚焦位置30cm的q2来聚焦的电压。 [0314] If 4225 is determined not achieve good decoding, the program proceeds to step 4230, where it will be applied to the fluid lens lens 920 a control signal is adjusted to a value in the first optional step, for example, result in the lens 920 to close focus position of 30cm q2 to focus voltage. 利用这种聚焦条件,在步骤4235捕获和处理一个图像。 With this focus condition, an image capture and processing in step 4235. 在步骤4240,检查从捕获的图像重新找回的信息以确定是否已经获得条形码的有效解码。 In step 4240, check from the captured image to retrieve the information to determine whether an effective decoded barcode. 如果解码是有效的,在步骤4260对报告的由被解码图像表示的信息和数据进行显示,并且程序停止,如步骤4270所指示的。 If the decoding is effective, information and data reported by the step 4260 pairs decoded image representation in the display, and the program is stopped, as indicated in step 4270.

[0315] 如果在步骤4240确定了没有达到良好的解码,程序继续到步骤4245,在那里将被应用到透镜920的所述流体透镜控制信号调节到第一可选值,例如导致透镜920以靠近聚焦位置IOOcm的q3来聚焦的电压。 [0315] If 4240 is determined not achieve good decoding, the program proceeds to step 4245, where it will be applied to the fluid lens lens 920 a control signal is adjusted to a value in the first optional step, for example, result in the lens 920 to close IOOcm focus position of the focusing voltage to q3. 利用这种聚焦条件,在步骤4250捕获和处理一个图像。 With this focus condition, an image capture and processing in step 4250. 在步骤4255,检查从捕获的图像重新找回的信息以确定是否已经获得条形码的有效解码。 In step 4255, check from the captured image to retrieve the information to determine whether an effective decoded barcode. 如果解码是有效的,在步骤4260对报告的由被解码图像表示的信息和数据进行显示,并且程序停止,如步骤4270指示的。 If the decoding is effective, information and data reported by the step 4260 pairs decoded image representation in the display, and the program is stopped, as indicated in step 4270. 如果条形码的有效解码仍然没有被完成,程序返回到步骤4215,并且重复该程序以尝试识别有效的条形码值。 If a valid decode the barcode is still not completed, the program returns to step 4215, and repeats the process in an attempt to identify valid barcode value. 在其他实施例中,在特定或预定数目迭代循环已经发生而又没有成功的输出时之后,或在特定或预定的时间之后,可以通过管理控制设备终止该程序,其在一些实施例中可以根据计算机程序操作。 In other embodiments, after a certain time or a predetermined number of iterations of the loop but did not succeed output has occurred, or after a specific or predetermined time, you can terminate the program by management control device in some embodiments according to Computer program operation. 可选地如果所述触发器被释放,所述程序可以停止。 Alternatively, if the trigger is released, the program can be stopped. 虽然描述在图57中的程序使用了三个离散条件来驱动透镜920以搜索合适的聚焦条件,对用户来说作为该程序的部分,超过或少于三个预定驱动条件是可能的。 Although the description of the program in Figure 57 uses three discrete condition to drive the lens 920 to search for an appropriate focusing conditions, the user, as part of this program, more or less than three predetermined driving condition is possible. 例如,我们可以定义程序,其中焦距以预定的距离或预定的百分比变化。 For example, we can define a program, in which the percentage change in the focal length by a predetermined distance or predetermined. 可选地,我们可以定义程序,其中所述调节是基于在是否所捕获的图像是聚焦(或上文描述的) 的评估中获得的信息或从被解码信息的质量(例如,所述信息是否完全被断章取义或被不正确地格式化,或者是接近有效的)确定的数量。 Alternatively, we can define the program, wherein the adjustment is based on whether the captured image is focused assessment information (or described above) or obtained from the decoded quality information (e.g., whether the information completely out of context or incorrectly formatted, or is close to the effective) amount identified. 通常,可以获得特定距离到绝对精确度(例如,不可以将30cm的距离测量为30. OOOcm的精确度,而仅仅是精确到分米十分之一的30cm)。 Typically, you can get a certain distance to an absolute accuracy (e.g., not the distance measurement is 30cm 30. OOOcm accuracy, but only to the nearest tenth of dm 30cm). 但是更确切地说试验是这样的,所述透镜充分地操作在确定的距离。 However, such tests are more specifically, the lens operation sufficiently determined distance. 在实验室,可以为实验设置精确距离,但是在实际应用中,距离的测量不如在实验室中那么精确。 In the laboratory, we can set the exact distance to experiment, but in practice, measuring the distance is not as accurate as in the laboratory.

[0316] 流体透镜可以具有误差,例如球面误差和/或色差。 [0316] fluid lens may have an error, such as spherical errors and / or color. 在本发明的聚焦模块中,可以使用附加透镜,例如正透镜或负透镜,来与例如透镜920的所述聚焦模块连接以校正球面的、颜色的、或更高状态的误差。 In the focusing module of the present invention, an additional lens can be used, e.g., a positive lens or a negative lens, connected for example to correct the spherical lens focusing module 920, or higher color error state. 在一些实施例中,可以选择所述附加透镜的结构材料以便补偿由所述流体透镜引入的光学不完整性或误差。 In some embodiments, the additional lens can be selected to compensate for the introduction of structural material by the fluid lens optical imperfections or errors.

[0328] 图64是表示用于多个示例性手持阅读器的校准曲线的图1800。 [0328] FIG. 64 shows a plurality of exemplary handheld readers of the calibration curve in Figure 1800. 在图64中,水平轴1802表示流体透镜控制信号参数,例如电压,而垂直轴1804表示所述流体透镜的光学性能,例如光学放大率光学放大率。 In FIG. 64, the horizontal axis 1802 represents the fluid lens control signal parameters, such as voltage, and the vertical axis 1804 represents the fluid lens optical properties, e.g., the optical magnification of the optical magnification. 它也可以表示流体透镜相应于它的操作的其他光学性能, 例如焦距、f数、和与默认光轴的偏移(其中默认光轴可以被考虑为表示相对高度的零度或方位的零度)。 It can also represent other fluid lens corresponding to the optical properties of its operations, such as the focal length, f number, and the default offset of the optical axis (optical axis which can be considered as the default represents zero or a relatively high degree of orientation of zero degrees). 在图64中,显示了三条曲线1810、1812、1814,每条曲线表示特别流体透镜对应用的流体透镜控制信号(例如电压)的响应(例如光学放大率)。 In Figure 64, shows three curves 1810,1812,1814, each curve represents the application of special fluid lens fluid lens control signal (eg voltage) response (such as optical magnification). 如在图64中所见的, 曲线1810,表示第一流体透镜的运行,在应用电压Vl 1830时达到光学放大率P 1820。 As seen in Fig. 64, curve 1810 represents the first run of the fluid lens, the application voltage Vl 1830 reaches the optical magnification P 1820. 然而,其他流体透镜可以轻不同地运行,以便由曲线1812表示的第二流体透镜在稍微大的电压V2 1832时获得光学放大率P,以及由曲线1814表示的第三流体透镜在更大的电压V3 1834时获得光学放大率P。 However, other fluid lens can run different light, so that the second fluid lens represented by curve 1812 in greater voltage optical power P, and the third fluid lens by curve 1814 represented slightly when a large voltage V2 1832 V3 1834 obtaining optical power P. 另外,我们可以从图64中的信息抽取在被应用到所述第一流体透镜和所述第二流体透镜以获得相同光学放大率P的所述流体透镜控制信号之间的关系, 例如为了操作两个手持阅读器在充分相似的条件下,或为了操作同时使用两个流体透镜的两用阅读器或其他设备,例如以产生目标的立体感视图。 In addition, we can extract the information from the FIG. 64 being applied to the first fluid and the second fluid lens to obtain a lens the same as the fluid lens optical power P of the control relationship between the signals, e.g., in order to operate Two handheld readers under substantially similar conditions, or to operate simultaneously with two fluid lens of dual-use reader or other device, such as to produce a three-dimensional view of the target. 在功率P,在驱动电压方面在所述第一透镜和所述第二透镜之间存在由V2-V1给出的差值,其中该差值具有由V2-V1的绝对值给出幅度以及符号,如果在幅度上V2大于Vl其符号是正的,幅度上Vl大于V2其符号是负的,如果V2 = Vl其符号是零。 Power P, in terms of the presence of the driving voltage V2-V1 is given by the difference between the first lens and the second lens, wherein the difference V2-V1 having a given amplitude, and the absolute value symbol If the magnitude is greater than Vl V2 its sign is positive, the amplitude Vl V2 which is greater than the negative sign, if V2 = Vl its symbol is zero. 在操作中为了在所述第一和第二流体透镜都获得光学放大率,我们可以提供等于Vl的流体透镜控制信号给所述第一和第而流体透镜,并且等于V2-V1的符号差值的差分信号给所述第二流体透镜。 In operation for the first and second fluids are given optical magnification lens, we can provide equal Vl fluid lens control signals to said first and second and the fluid lens, and is equal to the sign of the difference V2-V1 The differential signal to the second fluid lens. 可选地,我们可以用两个电源,它们各自提供信号Vl和V2给所述第一和第二流体透镜。 Alternatively, we can use two power supplies, each of which provides a signal Vl and V2 to the first and second fluid lens. 当用来操作所述流体透镜所需要的光学放大率变化,所述流体透镜控制信号也变化,并且可以从图64的合适曲线推导出来或读出来。 When the optical magnification change to the operation of the fluid lens needed, the fluid lens control signals change, and can be derived from the curve in Figure 64 fit out or read out. 由于基本上我们不测量流体透镜或其他设备在一个范围内的所有可能点的参数值,也可以通过测量离散数量对的光参数和相关流体透镜控制信号来获得例如1810的曲线,并且对所述数据拟合曲线,或者在相邻点插值,同样地可以方便地准备出合适的校准曲线。 Because basically we do not measure the fluid lens or other equipment all parameter values may point in a range to be measured by the number of discrete optical parameters and associated fluid lens control signal to obtain a curve such as 1810, and to the data curve fitting, interpolation or adjacent points, the same way you can easily prepare a suitable calibration curve. 在一些实例中,每个流体透镜模块仅有单个校准点可以被获得。 In some examples, the fluid in each lens module is only a single calibration point may be obtained. 胜于为不同流体透镜创建曲线,我们可以在不同的温度测量同一个流体透镜。 Create different curve than the fluid lens, we can measure the fluid with a lens at different temperatures. 随后在各种温度下可以确定合适的操作点。 You can then determine the appropriate operating point at various temperatures. 可以通过外插或内插、通过合适的曲线拟合关系、或以方程式的形式通过推导运行的表示来确定其他的点。 By extrapolation or interpolation, curve fitting relationship by a suitable, or in the form of equations represented by deriving run to determine the other points.

[0354] 这些新信号VI、V2、V3和V4的应用创建了二维偏移流体透镜,其中根据控制电压dh和dv的幅度和符号确定水平和垂直偏移角。 [0354] These new signals VI, V2, V3 and V4 of the application to create a two-dimensional fluid lens shift, which determine the horizontal and vertical offset angle based on the control voltage and dv dh magnitude and sign. 我们可以使用在模拟电路设计中被称为“累加电路”的已知电路,以及应用数字设计原理通过使用数字控制器,例如基于微处理器的控制器,和数模转换器产生这样的信号,包括叠加信号Vf和调节信号来产生合适的流体透镜控制信号。 We can use the known circuit in analog circuit design is called "accumulation circuit", and the application of digital design principles through the use of a digital controller, such as to produce such a signal microprocessor-based controller, and digital to analog converter, including the superimposed signal Vf and adjust signal to generate a suitable fluid lens control signal. 在图72中,流体透镜表面M45被显示为在垂直方向具有由于指示为Vl和V3的信号dv的应用而导致的偏移。 In FIG. 72, the fluid lens surface M45 is displayed with offset in the vertical direction due to the indication of Vl and V3 signals resulting from the application of dv. 不偏移的流体透镜的光轴M50显示为实质上沿着所述流体透镜的旋转轴,而偏离的或被调节的光轴由点线对阳显示,其关于旋转轴是不对称的。 M50 is not shifted to the optical axis of the lens is displayed as the fluid substantially along the rotation axis of the fluid lens, and the optical axis adjustment or deviation from the dotted line on the positive display, which is asymmetric with respect to the rotation axis. 注意表面M45不在提供聚焦曲率以提供焦距的期望光学放大率,而是充满用来调节光轴以校正所述手抖动或手移动的装置。 Note that the curvature of the surface of M45 does not provide focus to provide a desired focal length optical magnification, but full of used to adjust the optical axis to correct the hand-shake or hand mobile devices. 在其他实施例中,其他应用是可预期的。 In other embodiments, other applications are to be expected. 作为实例,我们可以设置所述透镜的焦距为很小的值(例如操作所述透镜作为具有宽视场和深视野的“鱼眼”透镜)并且利用所述光轴的调整使视场倾斜以便将在视场内感兴趣的某些特征带到更靠近视场中心。 As an example, we can set the focal length of the lens to a small value (for example, operating the lens as having a wide field of view and depth of field of vision of the "fish-eye" lens) and the use of the optical axis is inclined to adjust the visual field certain features of interest in the field of view is closer to the center of the field. 在鱼眼透镜中,在视场中心的特征当被观察时相对于视场的边缘具有最小化的光学失真,所以感兴趣的物体可以用降低的失真而被观察。 In the fish-eye lens, the center of the field characteristics when observed with respect to the edges of the field of optics with minimized distortion, so the object of interest can be used to reduce the distortion is observed. 另外,鱼眼透镜典型地在视场边缘将物体展开,以至于这样的操作可以增加感兴趣物体在图像传感器平面占据的像素的数量,从而提高可以被分辨的细节。 In addition, fish-eye lens is typically in the edge of the object to expand the field of view, so that such an operation can increase the number of the object of interest in the plane occupied by the image sensor pixel, thereby enhancing the detail can be resolved.

[0372] 另外,如已经被指出的,差别可以是由外部引入,例如施加的电压、周围或施加的压力、周围或施加的温度和加速力。 [0372] In addition, as has already been pointed out, the difference may be introduced by an external, e.g., applied voltage, applied pressure, or ambient, ambient temperature and the acceleration or force applied. 这些力可以各自地以及混合地导致一个流体透镜比标称上相同的流体透镜有稍微不同的操作。 These forces can be individually and in combination, led to a fluid lens on the same fluid than the nominal lens has a slightly different operation. 当在操作条件中这种差别存在,实质相同流体透镜控制信号在这两个透镜中的应用会导致每个透镜不同的操作性能。 When such differences exist in the operating conditions, the fluid lens substantially the same control signal is applied in the two lenses of each lens can cause different performance. 另外,为流体透镜提供简单的或准备被应用的校准方法,对以便可以校准每个透镜并为每个透镜提供合适的流体透镜控制信号以期望的方式来操作在属于那个流体透镜的特别条件下也是有帮助的。 In addition, the offer or prepare simple calibration method is applied to the fluid lens, so that you can calibrate next to each lens and provide appropriate fluid lens control signal for each lens in the desired manner to operate the special conditions of belonging to the fluid lens also helpful.

[0373] 然而为提供校准能力的另一个原因涉及在预定流体透镜操作中随着时间过去的变化。 [0373] Yet another reason to provide the ability to relate to a predetermined calibration fluid lens operations change over time in the past. 各个流体透镜的操作依赖于所述流体透镜的部件的化学、机械、和电性能的一个或多个,其性能会随着时间和使用变化。 One or more of the operations of the respective fluid lens is dependent on the fluid lens part of chemical, mechanical, and electrical properties, its performance will vary with time and use. 例如,如上文指出的,操作在响应于电信号的流体透镜可以承受在一个或多个流体中的电化学驱动反作用。 For example, as noted above, the operation in response to an electrical signal can withstand electrochemical fluid lens in one or more fluid driven reaction. 另外,作为受热过程的结果,流体可以随着时间改变性能,例如重复的加热和冷却循环或暴露于外部温度。 Further, as a result of process heat, fluid properties may change over time, such as repeated heating and cooling cycles or exposed to the outside temperature. 如将被理解的,当流体透镜的一个或多个部件的性能随着时间改变,校准感兴趣的操作条件或许是有利的。 As will be appreciated, when the performance of one or more components of the fluid lens changes with time, adjustment of operating conditions of interest may be advantageous.

[0374] 仍然在另一个实施例中,提供惯性设备例如加速计,来确定流体透镜的方向,其方向信息被用来自我校准所述流体透镜。 [0374] In still another embodiment, there is provided apparatus such as inertial accelerometers to determine the direction of the fluid lens, the direction information is used for self-calibration of the fluid lens. 重力和其他加速力会导致流体在自由边界、或两种流体互相接触的边界内移动和改变形状。 Acceleration of gravity and other forces can cause the fluid to move and change shape in a free boundary, or border the two fluids contact each other. 作为实例,考虑具有稍微不同密度的两种流体流体透镜。 As an example, consider a slightly different densities of the two fluids fluid lens. 不同密度意味着相同体积的两种流体将成比例地具有不同的质量,因为密度=质量/体积。 It means that two fluids of different density will be proportionately the same volume of different quality, since density = mass / volume. 因此,因为力(F)=质量X加速度,两种流体的相同体积在相同加速度情况下将经受稍微不同的力,例如重力加速度、或应用到支撑这两种流体的容器上的外部加速力的加速度。 Therefore, because the force (F) = mass X acceleration, the same volume of the two fluids in the same case will be subjected to slightly different acceleration forces, such as gravity, or externally applied to the support vessel on the two fluids acceleration forces acceleration. 这种被施以加速度的一种结果可以是作为结果的所述流体的相对位置的一种变化,在两种流体之间接触表面定义的界面的形状上的变化。 A result of this acceleration can be applied as a result of a change in the relative position of the fluid, it changes the shape of the contact surface between the two fluids on the definition of the interface. 另外,该加速度施加的方向也将影响到所述流体的反应。 Further, the direction of the acceleration applied to the reactor will also affect the fluid. 例如,被垂直施加到所述两种流体之间的平面界面的加速度比平行、正切施加到所述两种流体之间界面的平面部件具有更少的影响。 For example, the acceleration applied perpendicular to the plane of the interface between the two fluids than parallel to the planar member being 切施加 the interface between the two fluids has less influence. 因为该加速力大体上可以被施加在关于这两种流体之间的界面的任何角度,因此在回应依赖于所应用的加速力的精确方向方面,大体上将具有差别。 Since the accelerating force may be applied at substantially any angle with respect to the interface between the two fluids, so the response depends on the exact direction of acceleration forces applied aspects, we will have substantially different. 例如加速计和陀螺仪的惯性传感器在确定和在追踪物体随着时间的位置可以是有用的。 Such as accelerometers and gyroscopes in inertial sensors to identify and track objects in time as the position can be useful. 虽然这种惯性传感器的应用,识别物体的方向、以及测量应用的加速力的幅度和方向是可能的。 Although the magnitude and direction of acceleration forces inertial sensor applications, the direction of object recognition, and measurement applications are possible. 通过流体透镜的方向和包括重力的外力的知识计算或建模存在与所述透镜内的所述流体将怎样回应操作在所述透镜上的力是可能的。 Through knowledge of the direction of the fluid lens and the external force including gravity calculation or modeling how the presence of fluid within the lens will operate in response to a force on the lens are possible. 当上文呈现的描述可以被理解为描述线性加速力例如重力,执行追踪和流体对具有非线性成分的力、具有旋转成分的力、或随时间变化的力的回应的计算也是可能的。 When presented in the above description it may be understood to describe linear acceleration forces such as gravity, execution trace and fluid composition of the force with a non-linear, with the force rotation component, or in response to time-varying computing power are also possible. 在一些实施例中, 利用适于各种力的合适传感器,我们可以确定所应用的力与两种流体之间的相对方向,并且计算什么样的回应将是期望的。 In some embodiments, the use of appropriate force sensors for all, we can determine the relative direction of the applied force between the two fluids, and calculate what the response would be desirable. 作为计算的结果,提供信息用来及时地应用恢复力。 As a result of calculation, to provide information for timely application of resilience. 例如,通过修改电信号的幅度和/或场方向,如果需要作为时间的函数,所述流体界面的期望变形可以被抵消。 For example, by modifying the amplitude of the electrical signal and / or field direction, if required as a function of time, a desired deformation of the fluid interface can be offset. 在一个实施例中,提供固态加速计传感器,其操作在充分高的速度来确定外部力的幅度和方向。 In one embodiment, there is provided a solid-state accelerometer sensors, which operate at a sufficiently high speed to determine the magnitude and direction of the external force. 具有10000HZ的响应速率的加速计可以从位于4145 N First Street, San Jose,CA 95134 的Crossbow Technology 有限公司获得。 Accelerometers have the response rate from 10000HZ located 4145 N First Street, San Jose, CA 95134 of Crossbow Technology Co., Ltd. received.

[0375] 然而在其他实施例中,在包含流体透镜的装置中,操作所述流体透镜来提供对于例如由透镜的震动、位置、方向引起的畸变、由更高阶光学不完整性导致的色差、变形、以及由环境因素改变,例如压力改变而引起的色差的校正的性能。 [0375] However, in other embodiments, the apparatus comprising a fluid lens, the operation of the fluid lens chromatic aberration is provided for by the vibration of the lens distortion, for example, the position, orientation caused by a higher order optical imperfections caused by , deformation, and changed by environmental factors, such as pressure changes caused by the performance of the correction of chromatic aberration. 如已经在上文解释的,使用加速力作为例子,所述流体透镜可以在一些实施例中承受各种扭曲力或导致所述流体透镜的操作退步的、在操作中其是被期望的力。 As has been explained above, the use of acceleration as an example, the fluid lens may be subjected to various distorting forces in some embodiments, or cause the deterioration of the fluid lens, which in operation is desired force. 在其他实例中,所述流体透镜可以具有固有的不完整性,例如色差或更高阶不完整性。 In other examples, the fluid lens may have an inherent imperfections, such as color or higher order imperfections. 用各种方法分析这种光学不完整性是可能的,例如包含源、至少一个图像传感器、和硬件、和/或配置用来分析光学信息以评估是否在测试下在光学部件中存在误差和不完整性的软件的被校准图像系统的使用。 Analyzed by various methods such optical imperfections is possible, for example, comprise a source, at least one image sensor, and hardware, and / or configured to analyze the optical information to assess whether there is an error and does not in optical components in the test the integrity of the software is using a calibrated image system. 在其他实例中,被校准的测试系统在一些实施例中是适于应用在该领域的系统或装置,以便可以如果必要被不熟悉在试验室布置中所有的组合光学测试的人员以方便有效的方法执行周期校准。 In other instances, the test system is calibrated in some embodiments, the system or device suitable for use in the field, so that it can if necessary be unfamiliar with the staff in the laboratory arrangement all combinations of optical tests to facilitate effective The method of execution cycles calibration.

[0376] 在一个实施例中,所述光学元件可以在频域被建模作为传输函数,其中提供已知被应用输入信号I (s)并且测量被观察输出信号O(S)。 [0376] In one embodiment, the optical element may be modeled as a frequency-domain transfer function, wherein the input signal is applied to provide a known I (s) is observed and measured output signal O (S). 被观察的传输函数Hobs (s) =O(S)/ I(S)被确定。 Hobs observed transfer function (s) = O (S) / I (S) is determined. 随后可以将HobS(S)与期望的传输函数H(S)比较,以确定校正因子或关系C(S),其在测试下应该被应用到该系统以致使它如期望的那样执行,在这里C(S)HobS(S) = H(s),或C(S) =H(s)/Hobs (s)0 一旦确定了校正因子或关系C(s),它(或在时域它的等价替代)可以被应用来驱动流体透镜以便减少被观察的不完整性或多个不完整性。 Can then be HobS (S) with the desired transfer function H (S), to determine the relationship between the correction factor or C (S), which should be applied to the system under test such that it performed as expected, here C (S) HobS (S) = H (s), or C (S) = H (s) / Hobs (s) 0 Once the correction factor or relation C (s), it (or time domain in its equivalent alternative) can be applied to drive the fluid lens in order to reduce the observed imperfections or more of incompleteness. 传输函数概念、离散时间数学程序、数字滤波器和滤波方法、和能够处理需要的检测、分析和计算的、以及能够被用来应用校正作用的电路(包括硬件和或软件)被描述在许多关于实时数字信号处理的文章中。 Transfer function concept, discrete-time math program digital filters and filtering methods, and testing needs to handle, analysis and calculations, and can be used to apply corrective action of the circuit (including hardware and or software) is described in many About Articles real-time digital signal processing. 例如数字信号处理器的硬件在商业上可以从很多供应商获得。 Such as a digital signal processor hardware is commercially available from many suppliers.

[0377] 流体透镜的应用包括它们在一种或多种类型照相机中的使用,例如在蜂窝电话中的照相机,在高质量数字照相机中的使用,例如那些具有高倍数变焦透镜的照相机,以及在能够提供自动对焦、和平移、倾斜和缩放(“PTZ”)的照相机中的使用。 [0377] Application of the fluid lens include their cameras in one or more types of use, such as cameras in cellular phones, using high-quality digital cameras, such as those with a high multiple zoom lens camera, as well as in It provides auto focus, and pan, tilt and zoom ("PTZ") cameras in use. 平移是以扫动的移动来移动照相机,典型地水平地从一侧到另一侧。 Translational movement of the sweep is to move the camera, typically horizontally from side to side. 倾斜是垂直的照相机移动,例如在垂直于平移的方向上。 Tilt camera is moved vertically, for example in a direction perpendicular to the translation. 商业上可用的使用照相机和它的透镜重新聚焦的机械换向的PTZ视频或数字照相机是已知的,并且经常被用在监控中。 Use commercially available camera and its lens refocusing mechanical commutation PTZ video or digital camera is known and often used in monitoring. 为了完成这些特征,例如倾斜或平移,我们需要使两个光学不相似流体之间的界面相适应,以便对光轴从它原始的水平(平移)方向或原始的垂直(倾斜)方向进行重新定位,对于流体透镜,两个重新定位都可以用光轴在一个角度同时对水平和垂直方向单次重定方向来完成。 To accomplish these features, such as tilt or pan, we need to make two optical fluid interface between dissimilar adapt to optical axis from its original level (pan) direction or the original vertical (tilt) direction to reposition , the fluid lens, two can be used to reposition the optical axis at an angle to the horizontal and vertical directions at the same time a single reorientation to complete. 应用球面几何坐标容易计算这样的重定方向,但也可以用任意坐标系统,包括用三维坐标映射到二维坐标,例如常规地在X射线晶体学上做的那样作为例子。 Application of spherical geometry is easy to calculate such a reorientation, but you can also use any coordinate system, including mapping the three-dimensional coordinates to two-dimensional coordinates, for example, in the conventional X-ray crystallography done as an example. 一个完成所有自动对焦、平移、倾斜和缩放的方法是在单个设备中应用多个部件。 A complete all auto focus, pan, tilt and zoom method is the application of multiple components in a single device. 自动对焦和变焦已经在上文描述。 Auto focus and zoom has been described above. 通过提包含第一多个第一电极或至少一个第二电极的电极对,并且应用电压到该第一多个的至少一个电极和该至少一个第二电极以至于当关于所述流体透镜的光轴在应用电压之间被测量时,导致在所述流体透镜中的两种流体之间的界面的表面形状使不对称的测量改变,可以完成平移和倾斜,或更通常地, 光轴到不是与原方向共线的新方向的重定方向。 By providing a first electrode comprising a first plurality of the at least one electrode or second electrode pairs and the voltage applied to the first plurality of the at least one electrode and the second electrode such that the at least one optical lens when on the fluid When the shaft is measured between the applied voltage, resulting in the surface shape of the interface of the two fluids in the fluid between the lens of the measurement changes asymmetry, pan and tilt can be completed, or, more generally, to the optical axis is not reorientation and original direction collinear new direction. 大体上,为了完成不对称的提供,施加电压将包括不对称部件,和/或施加电压到其上的电极将被定位在不对称的几何位置关系。 In general, in order to provide complete asymmetry, including asymmetry of the applied voltage components, and / or applying a voltage to the electrode which will be positioned on the positional relationship of the asymmetric geometry. 通过施加具有不对称的电压场到所述流体透镜中的所述流体,所述流体将以一方式反应来调节跨过所述界面的电压梯度到尽可能均衡,从而致使所述流体占据包括不对称成分的界面形状,以及从而沿着与存在于应用电压之前的光轴不共线的新光轴引导光线。 By applying a voltage to said field having an asymmetric lens in the fluid flow, the fluid will be the reaction across the interface to adjust the voltage gradient to as a balanced manner, thereby causing the fluid does not occupy comprises symmetrical shape of the interface components, and thus along the new axis is present in the optical axis before applying the voltage non-collinear direct light.

[0378] 现在我们将简要地描述对于启动流体透镜是有用的电源的例子。 [0378] We will now briefly describe for starting the fluid lens is useful examples power. 在一个实施例中,用来驱动所述流体透镜的合适电源是方波电源,其偏向操作在0到V伏范围内,这里V 是正或负电压中的一个,其也可以被认为是单极供电。 In one embodiment, a suitable power source for driving the fluid lens is a square wave power, which tend to operate in the range of 0 volts to the V, where V is a positive or a negative voltage, which may also be considered monopolar powered by. 一个实施例是使用双极电源,其能够提供在+V1/2到-V1/2之间的电压,用增加+V1/2伏的偏置时,导致这个范围从0伏(= +V1/2伏偏置+[-V1/2伏]供应)到+Vl伏(=+V1/2伏偏置+V1/2伏供应)延伸,或者可选地用增加-V1/2伏的偏置时,导致这个范围从-Vl伏(=-V1/2伏偏置+[-V1/2伏] 供应)到0伏(=-V1/2伏偏置+V1/2伏供应)延伸。 One embodiment is the use of a bipolar power supply, it is possible to provide the voltage + V1 / 2 to -V1 / 2 between, with increasing bias + V1 / 2 volts, the result in this range from 0 V (= + V1 / 2 volt bias + [- V1 / 2 volts] supplied) to + Vl V (= + V1 / 2 volt bias + V1 / 2-volt supply) extension, or alternatively by increasing the bias -V1 / 2 volts When, resulting in the range from -Vl volts (= -V1 / 2 volt bias + [- V1 / 2 volts] supplied) to 0 volts (= -V1 / 2 volt bias + V1 / 2-volt supply) extension. 两个电压的相加是容易通过加法电路完成的,其许多变形是公知的。 The sum of the two voltages is readily accomplished by the addition circuit, many of which are well known in the deformation. 在一个实施例中,该偏置电压供应操作在固定电压上。 In one embodiment, the bias voltage supply operation at a fixed voltage. 在其他实施例中,基于可以通过设置开关被提供或在微处理器控制下的命令,该偏置电压供应被配置为提供多个定义电压。 In other embodiments, may be provided on or under microprocessor control by setting a switch command, the bias voltage supply is configured to provide a plurality of defined voltage. 在一些实施例中,被使用的电压可以被提供的数字信号控制,例如数字代码控制数模转换器定义输出信号值。 In some embodiments, the voltage may be used to control the digital signal is supplied, for example, the definition of a digital code control DAC output signal value. 在另一个实施例中,利用具有可控频率的脉冲链作为控制信号,可以应用电压供应,其利用频率到电压转换器控制,例如National Semiconductor的UC907或UC917频率到电压转换器。 In another embodiment, the use of a pulse train having a controllable frequency as the control signal, can be applied to the voltage supply, which utilizes frequency-to-voltage converter control, such as National Semiconductor's UC907 or UC917 frequency-to-voltage converter. 应该相信在所述流体透镜内的电化学反应在充分高的应用电压下是可操作的,从而使得在一些实例中使用单电极供应是有利的。 It is believed that within the fluid lens electrochemical reaction at sufficiently high applied voltage is operable so that the use of a single electrode supply in some instances is advantageous.

[0379] 在其他实施例中,提供具有从一伏到上百伏级别的正和负峰值电压的电压信号的电源供应被提供。 [0379] In other embodiments, providing a power supply is provided from one volt to hundreds of volts level of positive and negative peak voltage of the voltage signal. 在一些实施例中,由驱动器集成电路产生的方波提供输出电压,例如通常被用来操作场致发光灯,例如被设置于蜂窝电话中。 In some embodiments, the driver integrated circuit generates a square wave output voltage to provide, for example, is commonly used to manipulate EL lamp, for example, is provided in the cellular phone.

[0380] 图83是表示示例性流体透镜驱动电路四00的示意方框图。 [0380] FIG. 83 is a diagram showing an exemplary schematic block diagram of a fluid lens driving circuit 400 of. 该电路由电池供应2900供电,典型地运行于在3到4. 5伏的范围内,虽然可以设计用其他电压电池操作和从固定墙配备电源供应操作的电路。 The circuit is powered by a battery supply 2900, is typically run in the range of 3 to 4.5 volts, although other voltages can be designed for use with battery-operated and power supply circuit operating from a fixed wall. 电压参考四20被提供,其具有与低压降电源调节器关联。 4:20 voltage reference is provided, which has low dropout power regulator association. 提供以时钟信号(频率或脉冲链)形式的输入信号和数字数据线给I2C串行接口四30 用于这个驱动器电路受外部设备的控制,例如图55的微处理器4040。 Provided with a clock signal (frequency or pulse train) in the form of the input signal and the digital data lines to four I2C serial interface 30 is used to control external devices by the driver circuit, such as a microprocessor 55 4040. 串行接口四30与控制器四40通信(例如商业上可获得的微处理器)用来调整流体透镜驱动器电路四00、用来设置输出频率的振荡器四60、用来设置输出电压的数模(DAC)转换器四50的激活。 Four serial communication interfaces 40 and 30 four controllers (e.g., commercially available microprocessor) for adjusting the fluid lens drive circuit 400, to set the output frequency of the four oscillator 60, the output voltage is set to the number of analog (DAC) converter 50 of four activated. 提供来自电压参考四20的参考电压给该DAC。 It provides a reference voltage from the voltage reference to the four 20 DAC. 在一些实施例中,该DAC是10位DAC。 In some embodiments, the DAC is 10 DAC.

[0381] 控制器四40与提供时序信号的振荡器四60通信。 [0381] The controller 40 communicates with four oscillator provides timing signals Four 60. 通过从自外部源四62传送的合适信号,可以设计控制器四40进入省电状态,外部源四62在一些实施例中可以是用户也可以是另一个控制器。 By appropriate signal from an external source four 62 transmitted from the controller can be designed four 40 power-down, four external source 62 in some embodiments may be a user may be another controller. 这里可预期的控制器大体上是任何基于微处理器的控制器,包括微控制器、与存储器和编程指令关联的微处理器、或通用数字计算机。 Contemplated herein is any substantially controller microprocessor-based controller, including a microcontroller, associated with memory and microprocessor programmed instructions, or a general purpose digital computer. 控制器四40也与为桥驱动输出器四80生成方波信号的波形产生器四45通信。 The controller 40 also communicates with four waveform generator output is four bridge driver 80 generates a square wave signal of four 45. 通过控制器四40应用所述输出波形,波形产生器四45也与所述DAC转换器同步。 Four by the controller 40 to apply the output waveform, the waveform generator 45 is also synchronized with the four DAC converter.

[0382] DAC2950的输出设置高电压产生器四70的输出电压级别以便该输出电压与DAC2920的输出成比例,并且从而将其配置为被例如计算机的数字源高精度控制。 Output [0382] DAC2950 is set high voltage generator output voltage level to the output of four 70 output is proportional to the voltage and DAC2920, and thus it is configured to be a digital source such as high-precision control of the computer. 在一些实施例中,适当的反馈电路被包含在这个电路的一部分以在一输入电压、负载和环境条件范围内保持该输出电压为常数。 In some embodiments, the appropriate feedback circuitry is included in the circuit to within a portion of the input voltage, load and environmental conditions of the range of the output voltage is kept constant. 由高电压产生器四70产生的高电压输入到桥驱动器四80。 A high voltage is generated by four 70 generates a high voltage input to the bridge drive four 80. 对于Varioptic ASM-1000流体透镜,该高电压产生器具有一个稳定输出范围从OV到接近40V。 For Varioptic ASM-1000 fluid lens, the high-voltage generator having a stable output range from OV to approximately 40V. 这个产生器可以使用感应器四72和/或电容来生成该高电压。 The generator can use four sensors 72 and / or capacitance to generate the high voltage. 然而也可以使用其他电路配置,例如容性电压放大器。 However, other circuit configurations may also be used, such as a capacitive voltage amplifier. 桥驱动器四80生成驱动流体透镜四95的高电压开关信号OUTP和0UTM。 Bridge drive four 80 generates a high voltage switch drive fluid lens 95 and four signal OUTP 0UTM. 在一些实施例中,利用图58的整流电路,该输出可以被应用给例如流体透镜四95的负载。 In some embodiments, FIG rectifier circuit 58, and the output may be applied to the fluid lens e.g. 95 four load.

[0383] 给所述流体透镜的输出是电压信号,其是由桥驱动器利用来自所述波形信号发生器的波形信号成型的波。 [0383] to the fluid lens output voltage signal, which is made from the use of the bridge drive waveform signal generator waveform signal forming waves. 术语“桥驱动”应该可以如下被理解。 The term "bridge driver" should be understood as follows. 所述负载被连接在两个放大器输出之间(例如,它在两个输出端之间“搭桥”)。 The load is connected between the two amplifier outputs (e.g., between its two outputs, "bypass"). 这样的布局可以使在所述负载上的电压摆动成倍,相比于被连接到到地的负载。 This layout allows the voltage swing on the load doubled, compared to being connected to the ground of the load. 接地负载可以具有从零到放大器的输出电压的摆动范围。 Ground loads may have a swing range from zero to the amplifier's output voltage. 桥驱动负载可以看到两个这样的摆动,因为放大器可以驱动+端也可以驱动-端, 有效地使电压摆动加倍。 Bridge to drive the load can be seen two such swing because the amplifier can drive + terminal can also drive - end, effectively doubling the voltage swing. 因为电压两倍意味着功率四倍,这是有意义的提高,特别在电池大小指示低电供应压的地方应用,例如汽车或手持应用。 Twice the voltage means four times because of power, which is meaningful improvement, particularly in the size indicates low battery power supply voltage of local applications such as automotive or handheld applications.

[0384] 如已经指出的,我们也可以用合适幅度和极性的参考信号累加已描述的电路的输出,以便由所述负载承受的所述电压摆动是单极性的,但是正极或负极电压信号相对于地的幅度变为两倍。 [0384] As already indicated, we can also use the output circuit of appropriate magnitude and polarity of the reference signal accumulation has been described, the voltage in order to withstand the load from the swing is unipolar, but positive or negative voltage signal amplitude with respect to ground into a double. 刚刚提及的所述电压优点已经表现在这个实例中,因为电源P是由关系V2/R或V2/Z给出,这里V是电压,R是电阻,Z是阻抗。 The voltage advantage just mentioned have been shown in this example, since the relationship between the power P is given by V2 / R or V2 / Z, where V is voltage, R is the resistance, Z is the impedance. 因为在两个实施例中电压摆动是相同的ν伏(例如,从-ν/2到+ν/2,从0到+ν,或从-ν到0),因此有效功率没有改变。 Because in both embodiments voltage swing is the same ν volts (for example, from -ν / 2 to + ν / 2, from 0 to + ν, or from -ν to 0), so the effective power has not changed. 那些知晓机电工程原理的人对于明确叙述的内容是熟悉的,因为电气系统的参考电压(例如地电势)可以以随意方式来选择,仅从一个参考到另一个不同的参考转移应用电压到所述流体透镜应该不会改变分配给所述流体透镜的电源网络。 Those who know the mechanical and electrical engineering principles for a clear description of the content is familiar, because the electrical system of a reference voltage (for example, ground potential) can be selected in a random way, only a reference to a different reference voltage to the transfer application fluid lens should not change the allocation to the fluid lens power network. 然而,当从电化学原理的观点来考虑,应该认识到不同的电化学反应可以被构造发生(或可以被禁止),依赖于是否被应用的电压相对于所述参考电压是正极阈电压,或负极阈电压(例如在特别的化学系统中极性可以是很重要的特征)。 However, from the viewpoint of electrochemical principles to consider, should recognize that different electrochemical reactions can be configured occur (or can be disabled), depending on whether the voltage is applied with respect to the reference voltage is a positive threshold voltage, or negative threshold voltage (e.g., in a polar particular chemical system can be very important feature).

[0385] 图84和85是表示LED模3010以正方向发射能量通过流体透镜3020的图。 [0385] FIG. 84 and 85 is a LED die 3010 emit energy in the positive direction through a fluid lens 3020 in FIG. 该发射光的发散被用所述流体透镜修正。 Divergence of the emitted light is corrected by the fluid lens. 在图84中,该发射光的发散被修正因为所述流体透镜的光学放大率。 In Figure 84, the divergence of the emitted light is corrected because the optical power of the fluid lens. 在所示的实例中发射出所述流体透镜的光可以被考虑为接近校准的光, 即使射出的光是发散的。 Emitted in the example shown the fluid lens can be considered close to the light collimated light, even if light is emitted divergent. 在所述流体透镜的曲率比图84中所示的更大的一个位置,所述光没有被聚集在更小的一个区域。 The fluid lens curvature larger than a position shown in FIG. 84, the light is not gathered in a smaller area. 在图85中,所述流体透镜的功率已经被减小到接近零以至于被LED发射的光的发散是完全没被改变。 In Figure 85, the fluid lens power has been reduced to near zero so that the divergence of the light emitted by the LED is not changed completely. 在图84和85中的光图案的比较指示出这样的系统可以被用来控制对感兴趣的目标的覆盖(在区域上),例如用在手持阅读器或成像器的阅读的感兴趣的条形码。 In FIG. 84 and 85 of the optical pattern comparison indicates that such a system can be used to control coverage of the target of interest (in the region), for example, for use in hand-held bar code reader or imager reading interest . 在一些实施例中,也可以使用阅读器或扫描器上的一个或多个窗口来在不利的环境条件下保护包括所述流体透镜的所述光学系统。 In some embodiments, the reader can also be used or one or more windows on the scanner to protect includes the fluid lens of the optical system under adverse environmental conditions.

[0386] 应该注意,虽然细节可以改变,但是这个概念也可以应用到封装的LED上,也可以应用到可以包括例如球形、非球形、柱面透镜的附加光学元件的流体透镜组合上。 [0386] It should be noted, although the details may be changed, but the concept can also be applied to the package of the LED, can be applied to fluid lens compositions may include, for example spherical, aspherical, additional optical elements of the cylindrical lens.

[0387] 在一个实施例中,期望这样的系统更有效地利用该LED发射光的更多部分。 [0387] In one embodiment, such a system is more desirable to use more efficient light emitting portion of the LED. 例如当观测所述成像器附近的条形码,为了确定在其整个延伸上有更大的条形码图案被照亮, 期望更发散的照亮图案,以及当在离所述成像器更大的距离看条形码,更会聚的照亮图案是可期望的,以便照明不被由于落到感兴趣光域的外部而遭到浪费。 E.g., when the observer near the barcode imager, in order to determine with greater bar code pattern is illuminated, it is desirable to extend over the entire illuminated more divergent pattern, as well as when away from the imager to see a greater distance barcode more convergent illuminating pattern is expected to fall due to the external lighting is not interested in the optical domain and have been wasted.

[0388] 图87、88和89表示包含激光3110、校准透镜3120和流体透镜3130的激光扫描器在各种配置中的图。 [0388] FIG. 87, 88 and 89 denotes a laser scanner includes a laser 3110, 3120 and collimating lens fluid lens 3130 in various configurations. FIG. 在图86中,所述流体透镜被配置为具有第一光学放大率、第一焦距和第一主要光束方向。 In FIG. 86, the fluid lens is configured to have a first optical power, a first focal length and a first main beam direction. 从流体透镜3130发射的光束在位于离流体透镜3130为第一距离Dl 的平面3140上聚焦为具有最窄光束宽度。 3130 from the fluid lens focuses the light beam emitted by a light beam having the narrowest width from the fluid lens located on the first distance Dl 3130 to 3140 plan. 在图87中,所述流体透镜被配置为具有第二光学放大率、第二焦距和第一主要光束方向。 In FIG. 87, the fluid lens is configured to have a second optical power, a first focal length and a second main beam direction. 在图87中,从流体透镜3130发射的光束在位于离流体透镜3130为第二距离D2的平面3141上聚焦为具有最窄光束宽度,以至于D2大于D1,并且当所述流体透镜3130的焦距被改变时第一主要光束方向没被改变。 In FIG. 87, the fluid from the lens 3130 is focused on the light beam emitted from the fluid lens 3130 located at a second distance D2 from the plane 3141 having a narrowest beam width, so that D2 is greater than D1, and when the focal length of fluid lens 3130 when changing the first main beam direction has not changed. 在图88中, 所述流体透镜被配置为具有第一光学放大率、第一焦距和第二主要光束方向。 In FIG. 88, the fluid lens is configured to have a first optical magnification, the focal length of the first and second main beam direction. 在图88中, 从流体透镜3130发射的光束在位于离流体透镜3130为沿着图86的第二主要光束方向测量的相应于第一距离Dl的平面3140上聚焦为具有最窄光束宽度,但因为在图88中的光束是以一个角度发射的,该光束的横向距离是“偏轴”的Li。 In Figure 88, the fluid lens 3130 focuses the light beam emitted by a light beam having the narrowest width in the fluid lens 3130 is located away from the main beam along a second direction 86 of the measurement corresponding to the first distance Dl plane 3140, but Because the beam in FIG. 88 is an emission angle, the lateral distance of the beam is Li "off-axis" of. 通过正确地配置和激励流体透镜3130可以实现其他的光学放大率、焦距和主要光束方向。 By properly configured and encourage fluid lens 3130 may implement other optical magnification, focal length, and the main beam direction.

[0389] 本发明的目的在于利用流体透镜变焦光学系统的优点。 [0389] The present invention is to take advantage of the fluid zoom lens optical system. 流体变焦透镜配置可以被使用在条形码扫描以使得能够在离该条形码扫描仪的各种距离成像不同的条形码。 Fluid zoom lens configuration can be used to enable the bar code scanning the bar code scanner from various distances of different imaging barcode. 在如今制造的条形码扫描仪,通过缩小透镜部件的光圈以增加光域的深度,一般可以获得大的工作距离。 In today's manufacturing barcode scanners, by narrowing the aperture of the lens unit to increase the depth of the optical domain, generally you can obtain a large working distance. 然而这样有两个缺点:第一,当该透镜缩得越小,该光学系统点扩展功能增加从而扫描使用窄条形元件的图案更加困难。 However, this has two drawbacks: first, when the lens is reduced as small, the point spread function of the optical system is increased to scan using a narrow strip element patterns more difficult. 第二,当该透镜变得更小,更少的光进入到该透镜从而减少该系统的信号与噪声的比例。 Second, when the lens becomes smaller, less light enters the lens to reduce the signal-to-noise ratio of the system. 低的信噪比要求操作者静止地握持该阅读器更长的时间周期。 Low SNR require the operator to hold the reader is stationary for longer periods of time. 这种效果是该条形码扫描仪对手移动具有更高的敏感度。 This effect is the bar code scanner opponents move higher sensitivity. 另外,因为需要长周期的时间,用户将更可能变得疲劳。 In addition, because it takes a long period of time, users will be more likely to become fatigued.

[0390] 如果所述物体的范围或所述物体的距离是已知的,可以测量物体距离。 [0390] If the range of the distance to the object or the object is known, the object distance can be measured. 可以使用流体透镜系统实现范围查找系统。 You can use the system to achieve a fluid lens range finding system. 在一个实施例中,当由任意多个公制来确定,所述流体透镜将被聚焦在多个聚焦位置并且具有最佳聚焦的位置将与那个流体透镜位置相关联。 In one embodiment, when the metric is determined by any number of the fluid lens is focused at a focus position and having a plurality of best focus position that is associated with the fluid lens position. 通过知道导致所述所述流体透镜具有最佳聚焦图像的所述流体透镜驱动电压以及使用查找表, 对于那个特殊流体透镜操作电压可以确定距离系统的相关距离。 By knowing the cause of the fluid of the fluid lens having the optimum focus lens and the image of the driving voltage using a lookup table, for that particular fluid lens operating voltage can determine the relevant distance system. 通过知道所述范围,放大倍率可以被计算并且因此于在成像器上给定数目的像素关联的物体宽度是已知的或可以被推导的。 By knowing the range, the magnification can be calculated and therefore to the imager associated with a given number of pixels of the object width are known or can be deduced. 在这种情况下例如条形码阅读器或成像器的系统可以计算特殊物体特征的宽度,例如条形码元件宽度或包裹尺寸。 In this case for example, a bar code reader or imager system can calculate the width of the particular characteristics of the object, such as a bar code element width or package size.

[0391] 流体透镜可变部件可以被加到条形码系统中。 [0391] fluid lens variable component may be added to the barcode system. 在一些实施例中,该部件将被使用在光学系统的一部分中,该光学系统接收光并将允许该系统最佳地以光效率换取视场的点扩展功能宽度和深度。 In some embodiments, the components will be used in part of the optical system, the optical system receiving light and allow the system to exchange best light efficiency to the point spread function of the width and depth of the field of view. 当使用一个小的部件,该光学系统将具有大的视场深度,但不利的是该系统的光通过量是减少的(也就是说,更少的光通过该系统)并且该点扩展功能(也能够被分辨的最小元件尺寸成比例)也是降低的。 When using a small part of the optical system with a large depth of field, but the disadvantage is the amount of light passing through the system is reduced (that is, less light through the system) and the point spread function ( The minimum resolvable element size can be proportionally) is reduced. 在一些实施例中,期望将条形码系统配置为开始就具有该光学系统设有最佳光通过量,并且如果没有实现好的读取,那么为了延伸在解码可以在所述条形码扫描仪视场内的任何条形码图案的工作中的视场深度,可以减小该部件尺寸。 In some embodiments, it is desirable to configure the system to start the bar code of the optical system is provided with the optimal amount of light to pass through, and if not achieved good read, then extends to decode the barcode scanner in the field of view Work barcode pattern in any depth of field, the component size can be reduced.

[0392] 在一个实施例中,流体透镜被用作可变孔。 [0392] In one embodiment, the fluid is used as a variable lens aperture. 流体透镜的这种使用的一种执行包括增加着色剂到流体的至少一个以使那种流体在感兴趣的电磁频谱范围的至少一个区域不透明,例如在可见光频谱的特别范围内是不透明的。 An implementation of such lenses using a fluid comprising a colorant to the fluid to increase at least one fluid so that at least one opaque region of the electromagnetic spectrum of interest, e.g., within a particular range in the spectrum of visible light is opaque. 从电源施加电压到所述透镜以便缺少着色剂的所述流体在背靠相反窗口的特别区域“底部”吸收,从而在那个频谱范围内形成清晰。 Applying a voltage from the power supply of the fluid to the lens so that the lack of a colorant in the back area of the window opposite the special "bottom" absorbent, thereby forming a clear within that spectrum. 在一个实例中着色剂可以被加到油水流体透镜的水部分中。 In one example, the colorant may be added to the water portion of the aqueous fluid lens.

[0393] 在可选实施例中,如果窗口是弯曲的以便它有效地平行与水-油界面的弯曲,在一些实例中可以将该流体透镜配置为作为可变过滤器。 [0393] In an alternative embodiment, if the window is curved so that it is effectively in parallel with the water - oil interface bent, in some instances the fluid lens may be configured as a variable filter. 在这样的实施例中,所述油将不会背靠窗口在底部,而是将产生所述水的厚度,其本质上恒定地作为跨过该窗口一部分的半径的函数。 In such an embodiment, the oil will not be back at the bottom of the window, but the water will have a thickness as constant across the radius of the window function of a part of their nature. 这个厚度将通过改变被施加的电压而被变化。 This thickness will be varied by changing the voltage to be applied. 从而该吸收光的水的电压控制厚度将确定通过所述流体滤波器的光的数量。 So that the water absorption of light will be determined by the voltage to control the thickness of the fluid filter light quantity. 如果该着色剂在特殊的波长具有光吸收特性, 那么在这些波长内通过所述流体滤波器的所述光的幅度将通过改变该应用电压而被改变。 If the colorant having a specific wavelength of light absorption characteristics, so in these wavelengths by the filter, the amplitude of the light fluid will be changed by varying the applied voltage.

[0394] 通过具有超过一个透镜元件配置作为流体透镜,例如三个一组的透镜,因为透镜的组合,可以减少存在于单个元件的光色差,并且这将产生更高质量光学图像。 [0394] By having more than one lens element is configured as a fluid lens, e.g., a set of three lenses, because of a combination of lenses, can be present in a single device to reduce light color, and this will result in higher quality of the optical image. 最优化三个一组透镜技术在透镜设计领域是已知的。 Optimized lens technology in the design of a set of three field lenses are known. 然而,代表性的例子是为给定焦距系统最优化任何给定透镜。 However, the typical example is the system for a given focal length lens to optimize any given. 典型地,如果为了光学元件的一个组合而最优化透镜,当改变该透镜表面的一个并且碰巧当操作单个流体元件来改变光学参数,例如焦距时,它没有被最佳地配置。 Typically, if a combination of optical components for the most optimized lens, when changing one of the lens surface and happens when operating
