[0005] 变焦范围部分地由可移动透镜元件的移动范围确定。 [0005] The zoom range is determined in part by the movement range of the movable lens element. 更大的变焦范围可能需要用于透镜元件移动的额外空间。 Larger zoom range may require additional space for movement of the lens element.

[0020] 下面将参照附图进行描述。 [0020] Next will be described with reference to the drawings. 应理解,在不背离本发明的范围的情况下可使用其它结构和/或实施方式。 It should be understood, without departing from the scope of the present invention can be used where other structures and / or embodiments.

[0021] 液体透镜单元能够在不依靠液体单元的机械运动的情况下改变光路。 [0021] the liquid lens unit is capable of changing the optical path in the case where the liquid element does not rely on mechanical movement. 包括第一和第二接触液体的液体透镜单元可被配置为使得接触液体之间的接触光学表面具有可变形状,该可变形状可相对于液体透镜单元的光轴基本对称。 A first and a second liquid comprising contacting a liquid lens unit may be configured such that the contact between the optical surface contacting liquid having a variable shape, the shape can be variable with respect to the optical axis of the liquid lens unit is substantially symmetrical. 多个透镜元件可沿着公共光轴对齐并被配置为收集从物侧空间发出并传输至像侧空间的放射(radiation)。 A plurality of lens elements can be aligned along a common axis and configured to collect and transmit to the issue from the object side aerial image side space radiation (radiation). 液体透镜单元可被插入由沿着公共光轴对齐的多个透镜元件形成的光路中。 Liquid lens unit may be inserted into the optical path by a plurality of lens elements aligned along a common optical axis formed. 液体透镜单元的光轴可平行于公共光轴,或其可与公共光轴成一角度或偏离公共光轴。 The optical axis of the liquid lens unit may be parallel to the common optical axis, or at an angle or offset may be common optical axis with the common axis.

[0022] 目前预期的液体透镜系统的折射率之差为约0. 2或更大,优选地至少约0. 3,在一些实施方式中至少约〇. 4。 [0022] The difference in refractive index of the liquid lens system is currently expected is about 0.2 or greater, preferably at least about 0.3, at least about 〇 4. In some embodiments. 水具有约1. 3的折射率,且加盐后折射率可变为约1. 48。 Water has a refractive index of about 1.3, and the refractive index can be changed after the salt about 1.48. 适合的光学油可具有至少约1. 5的折射率。 Suitable optical oil may have at least a refractive index of about 1.5. 即使利用具有较高、较低、或较高和较低折射率的液体,例如较高折射率的油,焦度变化的范围仍然有限。 Even with the use of higher, lower, or higher and a lower refractive index liquid, e.g., a higher refractive index oil, power variation range is still limited. 焦度变化的有限范围提供的放大率变化通常比可移动透镜组的放大率变化小。 Magnification power change in a limited range of variation of the magnification provided by the change usually smaller than the movable lens group. 因此,在简单的可变焦度光学系统中,为了提供变焦的同时保持恒定的像面位置,大部分的放大率变化可通过一个可移动透镜组提供,放大率变化期间像面处的大部分散焦补偿可通过一个液体单元提供。 Thus, in a simple optical system of the zoom, the zoom in order to provide the image plane while maintaining a constant position, most of the change in the magnification by providing a movable lens group, the majority of scattered during magnification change at the image plane Coke compensation can be provided by a liquid unit.

[0023] 应注意,可利用更多的可移动透镜组或更多的液体单元,或可利用更多的可移动透镜组和更多的液体单元。 [0023] It should be noted, can use more movable lens groups or more liquid unit, or may use more movable lens group and more liquid unit. 在2008年10月6日提交的题为"LiquidOpticsZoomLens andImagingApparatus(液体光学变焦透镜和成像装置)"的第12/246, 224号美国专利申请中描述了结合一个或多个液体单元使用的一个或多个移动透镜组的实施例,其全部内容通过引用并入本文。 Entitled Oct. 6, 2008, submitted "LiquidOpticsZoomLens andImagingApparatus (liquid optical zoom lens and an imaging device)", Section 12/246, U.S. Patent Application No. 224 described in conjunction with one or more liquid unit uses one or more of Example mobile lens group, the entire contents of which are incorporated herein by reference.

[0024] 在系统中使用的透镜元件的尺寸和性质引入了在设计透镜系统时将要考虑的约束。 [0024] The size and nature of the lens elements used in the system introduced in the design of the lens system constraints to be considered. 例如,一个或多个透镜元件的直径可限制在像面上形成的图像的尺寸。 For example, the diameter of the one or more lens elements may be limited to an image formed on the image plane size. 对于具有可变性质的透镜系统,诸如可变焦度光学系统,光学器件可基于透镜元件的变化而改变。 For the lens system with variable properties, such as a zoom optical system of the optical device can be varied based on the lens element changes. 因此, 第一个透镜元件可将透镜系统约束在第一变焦配置中,同时第二透镜元件将透镜系统约束在第二变焦配置中。 Accordingly, the first lens element may be constrained in a first zoom lens system configuration, while the second lens element in the second zoom lens system is constrained configuration. 例如,光束的边缘光线可在变焦范围的一个极端处接近透镜元件的外边缘,并在变焦范围的另一个极端处显著远离相同透镜元件的外边缘。 For example, a beam of light can be close to the outer edge of the edge of the lens element at one extreme of the zoom range, and at the other extreme of the zoom range is significantly away from the outer edges of the same lens elements.

[0025] 图1A和1B示出采用液体透镜单元的简化的可变焦度光学系统的光学图。 [0025] FIGS. 1A and 1B shows a simplified using the liquid lens unit of the zoom optical system of the optical FIG. 可变焦度光学系统可以例如与相机一起使用。 Of the optical zoom system can for example be used with the camera. 在图1A中,第一液体透镜单元LLC1 20和第二液体透镜单元LLC2 22被配置为使得变焦比处于广角位置(wideposition)。 In FIG. 1A, a first liquid and a second lens unit LLC1 20 liquid lens unit LLC2 22 is configured such that the zoom ratio is in the wide-angle position (wideposition). 成像透镜24在与相机拾取装置相对应的像面(被示为像平面26)上形成图像。 In the imaging lens 24 and the camera corresponding to the image pickup device to form an image plane (image plane is shown as 26). 成像透镜24可以是液体透镜单元或其它透镜类型。 The imaging lens 24 may be a liquid or a lens unit other types of lenses. 图1A中所示的轴向光束的边缘光线12接近液体透镜单元LLC2 22 的外边缘。 Axial light beam 12 shown in the marginal ray approaching the outer edge of the liquid lens unit LLC2 22 of FIG 1A. 因此,液体透镜单元LLC2 22的直径是透镜设计中的限制因素。 Accordingly, the diameter of the liquid lens unit LLC2 22 is the limiting factor in lens design. 在图1B中,液体透镜单元LLC1 20和液体透镜单元LLC2 22被配置为使得变焦比处于长焦位置(tel印hoto position)。 In Figure 1B, the liquid lens unit LLC1 20 and the liquid lens unit LLC2 22 is configured such that the zoom ratio is in the telephoto position (tel printing hoto position). 图1B中所示的轴向光束的边缘光线12接近液体透镜单元LLC1 20的外边缘, 使液体透镜单元LLC1的直径成为限制因素。 Axial beam shown in FIG. 1B marginal rays 12 approaching the outer edge of the liquid lens unit LLC1 20 of the liquid lens unit LLC1 diameter becomes a limiting factor. 因此,对于位置范围之间的轴向光束的边缘光线12来说,图1A和1B中所示的简化设计被优化以完全利用液体透镜单元LLC1 20和液体透镜单元LLC2 22上的区域。 Thus, the axial position of the light beam between the edges of the range of the beam 12, Figures 1A and 1B shown in simplified design is optimized to take full advantage of the liquid lens and the liquid lens unit LLC1 20 LLC2 22 on the cell region.

[0026] 传统的变焦透镜系统利用移动变焦透镜组来获得不同的变焦位置。 [0026] The use of a conventional zoom lens system of the zoom lens group move to achieve different zoom positions. 因为图1A和1B中所示的可变焦度光学系统利用液体透镜单元,所以不需要移动透镜组。 Because of Figs. 1A and zoom optical system 1B shown by the liquid lens unit, it is not necessary to move the lens group. 相反,可使用控制系统来控制液体透镜单元LLC1 20和LLC2 22中的接触光学表面的可变形状。 Instead, you can use the control system to control the shape of the liquid lens unit variable 22 LLC1 20 and LLC2 contact optical surface.

[0027] 使用液体透镜单元取代移动透镜组便于光阑10在液体透镜单元LLC1 20和LLC2 22之间的放置。 [0027] The use of a liquid lens unit easy to replace the diaphragm moves the lens group 10 is placed between the liquid lens unit LLC1 20 and LLC2 22's. 因为液体透镜单元LLC1 20和LLC2 22不是移动透镜组,所以不需要关心光阑10将会干扰它们的正确操作。 Because the liquid lens unit LLC1 20 and LLC2 22 instead of moving lens group, so do not be concerned about the diaphragm 10 will interfere with their correct operation. 光阑10不需要等距设置在液体透镜单元之间,并且可根据需要优化光阑的放置。 Diaphragm 10 does not require equidistantly disposed between the liquid lens unit, and the placement of the diaphragm can be optimized as needed.

[0028] 应理解,液体透镜单元LLC1 20和LLC2 22均可包括多个表面,这些表面是可控的和/或固定的。 [0028] It should be understood, the liquid lens unit LLC1 20 and LLC2 22 may include a plurality of surfaces which are controllable and / or fixed. 在一些实施方式中,图1A和1B中所示的液体透镜单元可包括两个或多个液体单元的组合。 In some embodiments, the liquid lens units 1A and 1B shown may include a combination of two or more liquid elements. 在组合的单元之间可放置板。 In the combined unit can be placed between the plates. 该板可具有可以根据设计需要而设置的光焦度。 The plate may have optical power can be set according to design requirements. 液体透镜单元还可具有位于外表面上的板。 Liquid lens unit may have on the outer surface of the plate. 在一些实施方式中,外表面上的板可提供光焦度或折叠功能。 In some embodiments, the plate may be provided on the outer surface of the optical power or folding. 板和其它透镜元件可以是球面或非球面的,以提供改进的光学特性。 Boards and other lens elements may be spherical or aspherical, to provide improved optical characteristics.

[0029] 单独的透镜元件可由例如玻璃、塑料、结晶体或半导体材料的固相材料构成,或它们可利用例如水或油的液态或气态材料构成。 [0029] The individual lens elements may be formed such as glass, plastic, crystal or solid phase material constituting the semiconductor material, or they may be liquid or gaseous material using, for example water or oil composition. 透镜元件之间的空间可包含一种或多种气体。 The space between the lens elements may comprise one or more gases. 例如,可使用标准空气、氮气或氦气。 For example, you can use standard air, nitrogen or helium. 可选地,透镜元件之间的空间可为真空。 Alternatively, the space between the lens elements may be vacuum. 当本公开中使用"空气"时,应该理解使用的是广义含义,其可包括一种或多种气体,或真空。 When using the present disclosure, "air", it should be understood that the use of broad sense, which may include one or more gases, or a vacuum. 透镜元件可以具有诸如紫外线滤光片的覆层。 Lens element may have a coating such as a UV filter.

[0030] 图2A和2B示出图1A和1B的简化的可变焦度光学系统的附加的光学图,描绘了轴向光束的边缘光线12和离轴场射束的边缘光线14。 [0030] The additional optical Figure 2A and 2B shows and simplification 1B of FIG. 1A of the optical zoom system, depicting the axial marginal ray beam 12 and the off-axis field edge light beam 14. 离轴场射束的主光线16在光阑位置10处与光轴相交,光阑位置由位于边缘光线外的刻度标记指示。 Off-axis principal ray beam field 16 at the stop position 10 and the optical axis intersects the diaphragm position at the edge of the light from the outside of the scale numerals. 如图所示,离轴场射束的主光线16在像平面26上的入射角18随着变焦透镜从广角位置变为长焦位置而改变。 As shown, the off-axis principal ray beam field angle of incidence on the image plane 16 26 18 With the zoom lens from wide angle position to the telephoto position change.

[0031] 入射角是重要的,因为其在某种程度上决定到达图像传感器的光的量。 [0031] The angle of incidence is important because it determines the amount of light in a way to reach the image sensor. 图像传感器可使用微透镜以通过从大的光收集区域收集和聚焦光来改善光敏性。 The image sensor may use microlenses by light from a large collection area to collect and focus the light to improve photosensitivity. 然而,如果在变焦中入射角的尺寸和范围太大,那么微透镜可能不能将光引向图像传感器以在变焦中进行有效感测。 However, if the incident angle is too large in size and zoom range, the microlenses may be unable to light toward the image sensor for sensing the effective zoom in.

[0032] 考虑图3A-3D,其提供了到达图像传感器的光的示例性图示。 [0032] Consider Figure 3A-3D, which provide light reaching the image sensor of the exemplary illustration. 在图3A中,主光线28的入射角18垂直于图像传感器,以允许微透镜将光线顺利地引向图像传感器。 In FIG. 3A, 18 perpendicular to the chief ray angle of incidence to the image sensor 28, to allow the microlenses smoothly toward the light image sensor. 图3B和3C还具有入射角18的小变化。 Figures 3B and 3C also have a small change in the angle of incidence of 18. 微透镜阵列可被移动以形成优化的微透镜阵列,从而允许将光线顺利地重新引向图像传感器。 The microlens array may be moved to form an optimized microlens array, thereby allowing the light smoothly redirected to the image sensor. 图3D和3E具有更大的入射角18变化和尺寸,从而使得微透镜将光线引向图像传感器变得更加困难。 Figure 3D and 3E has a larger incident angle 18 and the size of the change, so that the light directed to the microlenses of the image sensor becomes more difficult.

[0033] 因为主光线28的入射角18随着可变焦度光学系统从广角位置变为长焦位置而改变,所以一个变焦位置的入射角18可能如图3B中所示,并且另一个变焦位置的入射角18 可能如图3C中所示。 [0033] Since the incident angle of the principal ray 28 of 18 of the optical system with zoom from wide-angle position to the telephoto position and change, so the incident angle of a zoom position may be shown in FIG. 18 3B, and another zoom position The angle of incidence of 18 may as shown in Fig. 3C. 然而,可能希望减少入射角18的变化。 However, it may be desirable to reduce the change in the angle of incidence of 18.

[0034] 图4A和4B示出液体透镜单元LLC3 30被置于图像传感器附近的光学图。 [0034] Figures 4A and 4B illustrate the liquid lens unit LLC3 30 is disposed near an optical image sensor in FIG. 当可变焦度光学系统在变焦范围内移动时,液体透镜单元LLC3 30的光焦度也发生变化。 When the zoom of the optical system can be moved within the zoom range, the liquid lens unit optical power LLC3 30 also changes. 液体透镜单元LLC3 30的可变光焦度使得在整个变焦范围内入射角在像面上的变化和尺寸最小化。 Liquid lens unit variable power LLC3 30 is such that the angle of incidence in the entire zoom range and size variation of the image plane is minimized. 例如,在一个实施方式中,液体透镜单元LLC3提供的入射角与垂直于像平面26的方向之间小于10。 For example, in one embodiment, the angle of incidence and the vertical liquid lens unit LLC3 direction provided between the image plane 26 is smaller than 10 . 在另一个实施方式中,液体透镜单元LLC3提供的入射角与垂直方向之间小于5。 In another embodiment, less than 5 between the incident angle and the vertical direction of the liquid lens unit LLC3 provided.

[0035] 虽然图4A和4B将透镜30示作液体透镜单元,但也可以使用其它类型的透镜。 [0035] Although Figures 4A and 4B shows the lens 30 as the liquid lens unit, it is also possible to use other types of lenses. 延长总的可变焦度光学设计可以允许使用标准透镜取代液体透镜单元。 Total extended zoom optical design allows the use of standard lenses replace liquid lens unit.

[0036] 可变焦度光学系统的长度部分取决于液体透镜单元所提供的光焦度的范围。 [0036] the length of the portion of the optical system of the zoom optical power depends on the scope of the provided liquid lens unit. 可通过利用具有高折光率差的液体的液体透镜单元使透镜的长度最小化。 Liquid lens unit may have a high refractive index difference between the liquid by utilizing the length of the lens is minimized. 也可通过利用多个液体透镜单元和/或折叠使透镜的长度最小化。 It may also be a plurality of liquid lens units and / or folded to minimize the length of the lens by using.

[0037] 为了简化起见,图认、18、24、28、4八和48将透镜元件示为包含光焦度的板。 [0037] For simplicity, recognition, 18,24,28,4 eight and 48 lens elements shown to board includes optical power. 应理解,透镜元件可以由具有不同的透镜材料和/或光学表面的多个部件构成。 It should be understood, the lens element may be a plurality of components having different lens materials and / or optical surfaces constituting.

[0038] 图5A-5E示出示例性可变焦度光学设计的光学图。 [0038] Figure 5A-5E shows an exemplary design of the optical zoom optical FIG. 图5A示出广角位置,图5E示出长焦位置。 5A shows the wide-angle position, shown in Fig. 5E telephoto position. 图5B-示出中间变焦位置。 Figure 5B- shows an intermediate zoom position. 无穷远聚焦(infinityfocus)被用于图5A-5E 中所示的所有位置。 Infinity Focus (infinityfocus) is used for all the position shown in FIG. 5A-5E.

[0039] 这种可变焦度光学设计利用5个液体透镜单元40、42、44、46和48,液体透镜单元40、42、44、46和48各自具有可变表面50、52、54、56和58。 [0039] This design makes use of the optical zoom 5 liquid lens units 40,42,44,46 and 48, the liquid lens unit 40,42,44,46 and 48 each have a variable surface 50,52,54,56 and 58. 物空间附近的透镜组包括两个液体透镜单元40、42并用于主要协助提供聚焦和变焦。 Near the object space lens group includes two liquid lens elements 40, 42 and used primarily to assist in providing focus and zoom. 可变焦度光学设计还包括用于主要协助提供变焦的两个液体单元44、46。 Design of the optical zoom also includes two major assistance provided for liquid unit zoom 44,46. 在所示实施方式中,光阑60位于包括液体透镜单元40、42的透镜组与包括液体透镜单元44、46的透镜组之间。 In the illustrated embodiment, the diaphragm 60 is positioned between the liquid lens unit including a lens group 40, 42 and the lens group includes a liquid lens unit 44,46. 可变焦度光学设计还包括液体透镜单元48,液体透镜单元48部分地提供对像平面62处的入射角的控制。 Design of the optical zoom lens unit 48 also includes a liquid, the liquid portion of the lens unit 48 provided on the image plane 62 of the angle of incidence of control. 所有5个液体透镜结合在一起以在可变焦度光学系统从广角位置变为长焦位置并且从无穷远聚焦变为近聚焦(closefocus)时提供对离轴场射束的主光线在像平面上的入射角、聚焦和变焦的控制。 All five of the liquid lens joined together to zoom in from wide-angle position of the optical system becomes telephoto position and focus changes from infinity to provide off-axis principal ray beam field close focus (closefocus) in the image plane angle of incidence, focus and zoom control.

[0040] 如图5A-ro所示,可变表面54所提供的光焦度保持完全恒定,并且仅在图5E中显著改变。 [0040] FIG. 5A-ro, the variable surface 54 provided by the optical power remain completely constant, and only significant change in Fig. 5E. 这说明如果变焦位置被限制在图5A-所示的范围,则可用固定透镜元件替换液体透镜单元44。 This shows that if the zoom position is limited as shown in FIG. 5A- range, the liquid can be used to replace the fixed lens element of the lens unit 44. 因此,液体透镜单元的数量可根据设计需要而发生变化。 Thus, the number of the liquid lens unit may vary depending on design requirements.
