具体实施方式 detailed description

[0017]下面将参照附图进行描述。 [0017] will be described with reference to the accompanying 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 invention may be practiced using other structure and / or embodiments.

[0018]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。 [0018] Liquid lens means capable of changing the optical path in the liquid cell without depending on the mechanical motion. 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。 Liquid lens unit comprises a first and a second contact with the liquid may be configured such that the contact between the optical surface in contact with a liquid having a variable shape, the shape may 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。 A plurality of lens elements may be aligned and configured to transmit the radiation emitted and the image side space of the collecting space from the object side along a common optical axis. 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 formed by a plurality of lens elements aligned along a common optical axis. 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 may be at an angle or offset from a common optical axis with the common optical axis.

[0019]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0.4。 [0019] 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, in some embodiments at least about 0.4. 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 becomes about 1.48 salt. 适合的光学油可具有至少约1.5的折射率。 Suitable optical oils may have a refractive index of at least 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 lower refractive index liquid, such as 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。 Limited range of variation of magnification power change is generally smaller than provide magnification change of 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 variable power optical system, in order to provide zooming the image plane while maintaining a constant position, most of the magnification change can be obtained by providing a movable lens group, most of the scattered at the image plane during magnification change focus-compensation may be provided by a liquid cell.

[0020] 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兀。 [0020] It should be noted, may be utilized more movable lens groups or more liquid cell, or may utilize more movable lens groups and a single additional liquid Wu. 在20〇8年10月6日提交的题为“Liquid Optics Zoom Lens and Imaging Apparatus (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 8 20 billion, filed October 6, the "Liquid Optics Zoom Lens and Imaging Apparatus (liquid optical zoom lens and the imaging device)" No. 12 U.S. Patent Application No. 246,224 / described in conjunction with one or more one or more embodiments of the movable lens group unit used in a liquid, the entire contents of which are incorporated herein by reference.

[0021]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。 [0021] The size and nature of the lens elements used in the system is introduced in the design of the lens system is constrained 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 limit the size of the image formed on the surface of the image. 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 a lens system with variable properties, such as a variable power optical system, the optical device may be changed based on a change of the lens element. 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,而第二透镜元件将透镜系统约束在第二变焦配置中。 Thus, a first lens element of the lens system can be constrained in a first configuration, zooming, 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, the edge ray of the beam near the outer edge of the lens element may be at one extreme of the zoom range, and significantly away from the outer edge of the lens element is the same at the other extreme of the zoom range.

[0022]图1A-1D示出形成中间图像108和最终图像107的简化的复合可变焦度光学系统的光学图。 [0022] Figures 1A-1D illustrates the formation of intermediate image 108 and the final image 107 may be simplified composite of the optical zoom optical system of FIG. 如图所述,光阑109被设置为刚好位于透镜的中继部分中的液体透镜单元104之后。 As shown, the diaphragm 109 is provided to the liquid lens of the lens unit 104 is located just after the relay portion. 可变焦度光学系统可以例如与相机一起使用。 A variable power optical system may for example be used with the camera. 图1A示出广角位置中的变焦比,而图1D示出长焦位置(telephoto position)中的变焦比。 1A shows the wide-angle position of the zoom ratio, while FIG. 1D illustrates the position of the telephoto zoom ratio (telephoto position) of.

[0023]图1A-ID所示的可变焦度光学系统不具有移动透镜组。 [0023] The variable power optical system shown in FIG. 1A-ID does not have the movable lens group. 相反,通过6个液体透镜单元101、1〇2、103、104、105和1〇6完成了最终图像处的变焦和恒定聚焦,其中液体透镜单元101、102、103、104、105和106各自具有可变的表面111、112、113、114、115和116。 In contrast, by the liquid lens unit 6 and 1〇6 101,1〇2,103,104,105 completed the final image at the zoom and focus constant, wherein the liquid lens unit 106 and each 101,102,103,104,105 111,112,113,114,115 and having variable surface 116. 可使用控制系统来控制液体透镜单元101、102、103、104、105和106中的接触光学表面的可变形状。 The control system may be used to control the liquid lens unit 101,102,103,104,105 and variable optical surface shape of the contact 106.

[0024] 应理解,每个液体透镜单元可包括多个表面,这些表面是可控的和/或固定的。 [0024] It should be understood, each of the liquid lens unit may include a plurality of surfaces is controllable and / or fixed. 在一些实施方式中,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 unit may comprise a combination of two or more liquid elements. 在组合的单元之间可放置板。 In combination 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 and may be provided depending on design requirements. 液体透镜单元还可具有位于外表面上的板。 Liquid lens unit further having 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 folded optical power or function. 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.
