[0032] 图1示出具有变焦透镜102的摄像机100的方框图。 [0032] Figure 1 shows a block diagram of a zoom lens 102 of the camera 100. 变焦透镜是能够改变焦距的透镜元件的组件。 The zoom lens is able to change the focal length of the lens element assembly. 单独的透镜元件可安装在适当的位置,或沿着透镜的本体轴向滑动。 Separate lens element can be mounted in place, or to slide axially along the body of the lens. 透镜组可由一个或多个透镜元件组成。 Lens group may consist of one or more lens elements. 至少一个可移动的透镜组提供物体放大率的变化。 At least one movable lens group provided object magnification change. 随着移动该至少一个透镜组以实现放大,焦平面的位置也可移动。 With the movement of the at least one lens group to achieve amplification, the position of the focal plane can be moved. 可移动至少一个其他可移动的透镜组来补偿该焦平面的移动,以保持恒定的焦平面位置。 At least one other movable lens group movable to compensate for the movement of the focal plane, in order to maintain a constant focal plane position. 还可通过当透镜放大率改变时移动全部透镜组件来机械地达到对焦平面移动的补偿。 But also by moving the entire lens assembly when the lens magnification change to achieve compensation for mechanically moving the focal plane.

[0033] 单独的透镜元件可由固相材料构成,例如玻璃、塑料、结晶体或半导体材料,或利用液态或气态材料构成,例如水或油。 [0033] The lens member may separate the solid phase material, such as glass, plastic, crystal or semiconductor material, or the use of liquid or gaseous material, such as water or oil. 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 element may be the 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,或为真空。 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.

[0034] 变焦透镜通常具有三个或更多移动的透镜组以实现变焦和聚焦功能。 [0034] The zoom lens typically has three or more movable lens group to achieve a zoom and focus functions. 机械凸轮可将两个可移动的透镜组连接以进行变焦,而第三可移动的透镜组可用于聚焦。 Mechanical cam can be two movable lens groups connected for zoom, while the third movable lens groups can be used to focus.

[0035] 变焦范围部分地取决于可移动的透镜元件的移动范围。 [0035] The zoom range depends in part on the movement range of the movable lens element. 大的变焦范围需要用于透镜元件移动的额外空间。 Large zoom range requires additional space for movement of the lens element. 实施液体单元技术的透镜组可替换一个或更多可移动的透镜组。 Lens group to implement liquid cell technology can replace one or more movable lens groups. 因为液体单元不需要轴向移动的空间,因此可减少包含可移动的透镜组的透镜设计的长度。 Because the liquid element does not require axial movement of the space, thereby reducing the lens design contains a movable lens group length. 可选地,用于可移动的透镜组移动的空间可用于包括额外的光学元件或光学折层(optical folds)。 Alternatively, for a movable lens group moves include space for additional optical components or optical folds (optical folds). 虽然液体单元不需要移动用的空间,但是液体单元可作为可移动的透镜组的一部分。 Although liquid unit does not need to move a space, but liquid unit can be used as a movable lens group part.

[0036] 液体单元可用于变焦和聚焦。 [0036] Liquid unit can be used to zoom and focus. 在一个实施方式中,可移动的透镜组与实施液体单元技术的透镜组一起使用。 In one embodiment, for use with a movable lens group and the technical implementation of the liquid lens unit group. 不需要具有一个可移动的透镜组的机械凸轮。 You need not have a mechanical cam movable lens group. 不具有凸轮允许额外的移动。 No moving cam allow extra.

[0037] —个或多个可移动的透镜组与一个或多个液体单元一同使用以实现变焦和聚焦。 [0037] - one or more movable lens group and one or more liquid unit used together to achieve the zoom and focus. 单一的可移动的透镜组和单一的液体单元可一起实施变焦、聚焦以及热效应的补偿。 Single movable lens group and a single liquid unit may be implemented together zoom, focus and compensate for thermal effects. 在一种实施方式中,变焦系统至少具有第一和第二透镜组。 In one embodiment, the zoom system having at least a first and a second lens group. 第一透镜组为相对高光焦度的,而第二透镜组为相对低光焦度的,透镜光焦度等于透镜焦距的倒数。 The first lens group is relatively high optical power and the second lens group is relatively low optical power of the lens optical power equal to the reciprocal of the focal length of the lens. 第一透镜组包括常规玻璃透镜或其他固体透镜,第二透镜组包括至少一个液体透镜。 The first lens group comprises a conventional glass lens or other solid lens, the second lens group comprises at least one liquid lens.

[0038] 液体单元使用两种或更多种液体来形成透镜。 [0038] Liquid unit uses two or more liquids to form a lens. 透镜的焦距部分地由液体之间的接触角和液体间的折射率差异来确定。 Lens focal length is determined in part by the difference in refractive index between the contact angle between the liquid and the liquid. 光焦度变化的范围受到所采用的液体的折射率的差异和因空间约束在液体之间的表面交界处产生的曲率半径的有限范围的限制。 The range of difference in refractive index change by the optical power of the liquid used and limited range due to space constraints in the radius of curvature at the junction surface between the liquid generated by the restrictions. 通过引用并入本文的公开号为2006/0126190的美国专利申请,公开了一种采用通过电润湿法产生液滴变形的透镜。 Incorporated herein by reference, U.S. Patent Application Publication No. 2006/0126190, there is disclosed a method using a droplet deformation generated by electrowetting lens. 通过引用并入本文的第6,936,809号美国专利,公开了一种使用电润湿技术以横向偏移在像面上形成的图像。 Incorporated herein by reference, U.S. Patent No. 6,936,809, discloses a method of using electrowetting technique to lateral offset of the image formed on the image plane. [0039] 目前预期的液体透镜系统的折射率之差至少约0. 2,优选地至少约0. 3,在一些实施方式中至少约为0.4。 [0039] difference in refractive index of the liquid lens system is currently expected to be at least about 0.2, 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 can be changed with salt about 1.48. 适合的光学油(optical oils)可具有至少约1. 5的折射率。 Suitable optical oil (optical oils) may have at least a refractive index of about 1.5. 甚至利用具有较高、较低或较高和较低折射率的液体,例如较高折射率的油,光焦度变化的范围仍受到限制。 Even with higher utilization, lower or higher and a lower refractive index of the liquid, such as a higher refractive index of oil, changes in optical power range is still limited. 受限的光焦度变化范围通常提供比可移动的透镜组小的放大率变化。 Optical power range generally provide limited than with removable magnification lens group small change. 因此,在简单的变焦透镜系统中,为了提供变焦同时保持恒定的像面位置,通过一个可移动的透镜组提供大部分的放大率变化,且通过一个液体单元提供放大率变化期间像面上大部分的散焦补偿。 Thus a large image plane, in a simple zoom lens system, while maintaining a constant in order to provide a zoom position of the image plane, through a movable lens group to provide most of the magnification change, and by providing a liquid during the magnification change unit defocus compensation section. 然而,应该注意,可利用更多的可移动的透镜组或更多的液体单元,或利用更多的可移动的透镜组和更多的液体单元。 However, it should be noted, can be used more movable lens groups or more liquid unit, or use more movable lens group and more liquid unit.

[0040] 可移动的透镜组可具有正或负光焦度。 [0040] movable lens group may have a positive or negative power. 液体单元可具有一定范围的可变光焦度, 其中光焦度总为正、总为负或从正变为负或从负变为正。 Liquid unit may have a range of variable optical power, wherein the optical power is always positive, always negative, or from positive to negative or from negative to positive. 可移动的透镜组和液体单元的适当布置可提供大于2倍且优选地大于3倍的扩展的变焦比,且同时在整个变焦范围内提供良好的图像质量。 May suitably arranged movable lens group unit and a liquid may provide more than 2-fold and preferably greater than 3 times the zoom ratio of expansion, and while providing good image quality over the entire zoom range. 除变焦之外,该布置还可通过利用来自液体单元、可移动的透镜组或两者的额外可获得的光焦度变化,在扩展的聚焦范围内的不同物距处提供聚焦。 In addition to the zoom, the arrangement can also take advantage of the extra change of power available movable lens group, or both from the liquid unit over an extended range of different object distance focused at providing focus. 液体单元或可移动的透镜组或者两者为聚焦所提供的额外光焦度变化是容易获得的。 Liquid unit or additional optical power changes movable lens group or both a focused offer is readily available. 由于一个可移动的透镜组不需要具有固定移动轨迹的凸轮,因此可调节可移动的变焦透镜组的位置以变焦和聚焦。 Since a movable lens group need not have a fixed cam track moving, thus adjusting the position of the movable lens group of the zoom to zoom and focus. 通过利用可移动的变焦透镜组和液体单元进行变焦和聚焦实现了高性能成像。 By using a zoom lens group and a liquid unit movable zoom and focus to achieve a high-performance imaging.

[0041] 还可用至少一个液体单元替换可移动的变焦透镜组。 [0041] may also replace the movable zoom lens group with at least one liquid unit. 这将增加光学系统的复杂性,并导致光学系统具有其他缺点,例如减小的放大率变化。 This will increase the complexity of the optical system, and lead to the optical system has other disadvantages, such as decreasing the magnification change.

[0043] 在控制液体之间的表面的曲率半径或可移动的透镜组的位置或者两者时还可考虑热效应。 [0043] In controlling the position of the surface of the liquid between the radius of curvature or movable lens group or both may also consider the thermal effect. 多项式或查找表可包括额外的与热效应相关的变量。 Polynomial or lookup table may include additional variables associated with thermal effects.

[0113] 可以理解,在极端焦点位置Fl与F3之间可以获得连续聚焦,在极端变焦位置Zl 与Z8之间可以获得连续变焦,在所描述的聚焦和变焦范围内通过透镜系统60可以获得连续聚焦和变焦的任何组合。 [0113] can understand, you can obtain a continuous focus between extreme focus position Fl and F3, in the continuous-zoom can be obtained between the extreme zoom position Zl and Z8, in the focus and zoom range described by the lens system 60 can obtain a continuous Any combination of focus and zoom.

[0114] 图2中所示出和表1中所规定的变焦透镜系统60对于透镜组Gl和G2分别具有54. 30和-12. 25mm的焦距。 [0114] As shown in Figure 2 and Table 1 in the specified zoom lens system 60 for the lens group Gl and G2 respectively 54.30 and -12. 25mm focal length. 而且,由于液体之间的光学表面21的形状可变,透镜组G3具有可变焦距,该可变焦距在变焦位置Zl和焦点位置Fl处、以及变焦位置Z8和焦点位置F3 处分别具有最小值+30. 18mm和最大值+38. 97mm。 Further, since the shape of the optical surface of the liquid between the variable 21 having a variable focal length lens group G3, the variable focal length in the zoom position Zl and focus position Fl point, and the zoom position and focus position F3 Z8 has a minimum value at each +30. 18mm and maximum +38. 97mm. 图3A和3B中示出了变焦透镜系统60的液体单元LC,其中显示了液体之间的形状可变的光学表面21的来自表1的两个极值曲率半径。 3A and 3B are shown LC liquid unit zoom lens system 60, which shows the shape of the liquid between the variable optical surface from the two extremes of the radius of curvature 21 of Table 1. 在图3A和3B中,表面21的两个曲率半径分别约为-33. 99和+115. 80mm。 3A and 3B, two radii of curvature of the surface are about 21 -33. 99 and +115. 80mm. 在图3A和3B中,液体单元LC的两个极值焦距分别为-185. 20和+630. 97mm。 3A and 3B, the liquid cell LC are two extreme focal length -185 20 and +630. 97mm. 这种差异发生在变焦位置Zl和焦点位置Fl处以及变焦位置Z8和焦点位置F3处。 This difference occurs in the zoom position Zl and focus position and zoom position Z8 at Fl and F3 at the focus position. 在该实施方式中,表面20、21 和21、22之间的两种液体的体积随着可变表面形状的变化而变化。 In this embodiment, the volume of the two liquids 20, 21 and 21 between the surface with variable surface shape changes. 然而,也可以通过使表面20、21和21、22之间的轴向间隔发生小的、相等但相反的改变,以保持每种液体的体积恒定。 However, it may be 20, 21 and 21 by the axial surface interval between the occurrence of small, equal but opposite change in order to maintain a constant volume of each liquid.

[0115] 现在参照4A、4B、和4C,其中示出变焦透镜系统60具有处于不同位置的变焦透镜组、处于不同位置的液体单元中的可变表面的形状以及对于这些位置的光线踪迹。 [0115] Referring now 4A, 4B, and 4C, there is shown a zoom lens system 60 having a different position in the zoom lens group, the shape at different positions of the liquid surface of the unit and a variable light traces for those positions. 图4A表示了焦点位置Fl和变焦位置Z1,表1中以无穷远的焦点和约为5. 9mm的较小焦距阐明了针对焦点位置Fl和变焦位置Zl的数据。 Figure 4A shows the focus position Fl and zoom positions Z1, the focus to infinity in Table 1 and the smaller the focal length of about 5. 9mm clarify the data for the focus position and zoom position Zl of Fl. 图4B以表1中的中间焦点和约11. 3mm的焦距表示了焦点位置F2和变焦位置Z3。 In Figure 4B the intermediate focus Table 1 indicates the focal length of about 11. 3mm focus position F2 and the zoom position Z3. 图4C以表1中的近焦点和约44. 8mm的焦距表示了焦点位置F3和变焦位置Z8。 Figure 4C to near focus in Table 1 and about 44. 8mm represents a focal length of the focus position F3 and zoom position Z8.

[0116] 图4A、4B和4C示出了分别对于各自的变焦位置和焦点位置:Z1、Fl和Z3、F2和Z8、F3,具有可变光学表面21的相应的3个表面形状的变焦透镜组G2的3个轴向位置。 The zoom lens Z1, Fl and Z3, F2 and Z8, F3, having a variable optical surface shape of the corresponding surface 3 of 21: [0116] Figures 4A, 4B and 4C show, respectively, for each zoom position and focus position Group 3 of the axial position of G2.

[0117] 图5A、5B和5C中给出了变焦透镜系统60的光学性能,其中以表1中所给出的变焦位置和焦点位置的三种不同组合,即作为代表性示例的(zi,Fl)、(Z3,F2)、和(Z8,F3), 对于五个不同的场位置,以百分比(% )示出了基于衍射的的多色调制传递函数(“MTF”) 数据(调制与空间频率的关系)。 [0117] Figures 5A, 5B and 5C shows the optical performance of the zoom lens system 60, a combination of three different zoom position and the focal position of which are given in Table 1, i.e., as a representative example of (zi, Fl), (Z3, F2), and (Z8, F3), the field for five different positions, as a percentage (%) shows the data (based on the modulation and diffraction of polychromatic modulation transfer function ("MTF") spatial relationships frequency). 以两个数值给出所述场位置,即归一化的图像高度(mm) 和相对于光轴的实际物空间角度(度)。 In the two values given in the field position, namely the normalized image height (mm) and with respect to the optical axis of the actual object space angle (degrees). MTF百分比处于在图5A、5B和5C的右上角记录的波长和权重处,并以图形方式示出像面36上测量的切向(T)和径向(R)。 MTF percentage in the FIGS. 5A, 5B and 5C wavelength and right of the top right corner of the weight of the record, and graphically shows the image on the surface of the 36 measured tangential (T) and radial (R). 注意,切向和径向值在轴向场位置(轴)处是相等的并仅用一个图来描绘。 Note that the value of the tangential and radial axial field position (shaft) are equal and only at a map to depict. 给定约6mm的图像直径,所示出的最大空间频率为90周/mm,对探测器像素尺寸的选择可以提供至少高达高清电视(HDTV)分辨率,即1920个水平像素乘1080个竖直像素的高质量图像。 Given about image 6mm diameter, the maximum spatial frequency is 90 weeks illustrated / mm, the detector pixel size selection can provide at least as high definition television (HDTV) resolution that 1920 horizontal pixels by 1080 vertical high quality image pixels. 空间频率处的MTF是光学性能的相对标准的测量,其中数值“90周/mm”意味着在用于确定清晰度的图上每毫米90 对黑白线。 MTF at the spatial frequency is relatively standard measurement of optical properties, wherein the value "90 weeks / mm" means for determining the 90 pairs of lines per millimeter on a black and white clarity of FIG. 最高的MTF值约为89%,处于对于变焦位置Zl和焦点位置F2的全径向场。 Highest MTF value of approximately 89%, in the zoom position Zl and focus position F2 full radial field. 最低的MTF值约为58%,处于对于变焦位置Z2和焦点位置F3的全切向场。 MTF minimum value of approximately 58%, in the zoom position and focus position Z2 F3 full cut to the field. 最小相对照度约为75%,处于变焦位置Zl和焦点位置F1。 The minimum contrast of about 75%, in the zoom position Zl and focus position F1. 通常,相对照度值越高越好,因为低的数值意味着光在图片的角落减少。 Generally, the higher the better contrast values, because of the low value means that light decreases in the corner of the picture. 对于现有技术的探测器而言,较高的全场相对照度是优选的,现有技术的探测器在所有区域中具有对光的恒定响应,并且在变焦过程中连同图像的改变忠实地重现图像角落中的阴影。 For the prior art detector, the high contrast of the audience is preferred, prior art detectors have a constant response to light in all areas, and during zooming along with changing the image faithfully weight Now the image corners shadow. 小于50%的照度可能导致电子探测器中的阴影,但是对于胶片而言可能是可接受的。 Illumination of less than 50% may result in a shadow electron detector, but for the purposes of the film may be acceptable. 最高正畸变为变焦位置Z3和焦点位置Fl处的+3. 04%,最低负畸变为变焦位置Zl和焦点位置F3处的-2. 98%。 Highest orthodontics becomes +3. 04% zoom position and focus position Fl Z3 at the lowest negative distortion -2. 98% zoom position Zl and focus position F3 at. 通常,所谓的透镜“呼吸”问题(但是可能在变焦透镜中更为普遍),即从远焦到近焦图像尺寸发生改变,在变焦透镜系统60中在变焦范围的短焦距处实际上是不存在的,而由于景深较大该问题在变焦范围的短焦距处最可能被注意到。 Typically, so-called lens "breathing" problem (but may be more common in zoom lens), which changed the focus from far to near focus, image size, the zoom lens system 60 in the short focal length of the zoom range is not actually exist, and since a large depth of field of the problem in the short focal length zoom range of the most likely to be noticed. 最低呼吸为变焦位置Zl和焦点位置F3处的-0. 2%,最高呼吸为变焦位置Z8 和焦点位置F3处的-19. 5%。 Lowest breathing -0. 2% zoom position Zl and focus position F3 at maximum breathing -19. 5% zoom position and focus position F3 Z8 at. 呼吸是从无穷远焦点到所选择的焦点最大视场角的百分比变化。 Breathing is from infinity focus to the largest percentage change in the focus of the selected field of view angle. 因此,在无穷远焦点(Fl)处,呼吸为零,因为它是参考视场。 Thus, at infinity focus (Fl) at breathing zero because it is a reference field.

[0212] 透镜系统80具有的畸变特征与具有略微增加的全场畸变(fullfield distortion)的透镜系统60的畸变特征相似,由于液体透镜是偏心的,单元系统60的全场畸变略微地不对称。 [0212] Characteristics of distortion of the lens system 80 has a similar distortion characteristics of the lens system has a slightly increased audience distortion (fullfield distortion) of 60, since the liquid lens is decentered, the whole system unit 60 slightly asymmetrical distortion. 透镜系统80基本上是非渐晕的,并且相应的相对照度非常高并与透镜系统60的照度相似。 Lens system 80 is substantially non-vignetting, and the corresponding contrast is very high and similar to the illumination lens system 60. 透镜系统80具有的呼吸特征基本上与透镜系统60的呼吸特征相似。 Respiration of the lens system 80 has a substantially similar characteristics and respiratory lens system 60.

[0213] 给定约6mm的图像直径,所示出的最大空间频率为60周/mm,对探测器像素尺寸的选择可以提供至少高达标清电视(SDTV)分辨率,即720个水平像素乘480个竖直像素的高质量图像。 [0213] diameter of about 6mm a given image, the maximum spatial frequency illustrated as 60 weeks / mm, the detector pixel size selection can provide at least a high standard-definition television (SDTV) resolution, ie 720 horizontal pixels by 480 a vertical pixel high-quality images. 在图11中,在长焦距处,在通常实际上没有远距离位置和中间距离位置即F1 和F2重要的近焦位置(Z8,F3),光学性能(MTF)减小至约55%。 In Figure 11, the long focal length, usually not actually a remote location in the middle distance and position that is close to F1 and F2 important focus position (Z8, F3), the optical performance (MTF) was reduced to about 55%. 然而,在远距离处稳定操作时,光学性能(MTF)维持在约60%以上。 However, in the far distance a stable operation, the optical performance (MTF) is maintained at about 60%. 可移动的透镜组82在稳定期间可轴向移动,且液体透镜单元的可变曲率半径在稳定期间可独立的变化,这允许光学性能升至或超过大致相当于HDTV分辨率的90周/mm。 The movable lens group 82 during stationary axially movable, and a variable radius of curvature of the liquid lens unit during a stable and independent of variations, which allows the optical properties substantially equivalent to the raised or HDTV resolution than 90 weeks / mm .

[0214] 图12A-12D与图9A-图9D示出的光学配置相对应。 [0214] FIG. 12A-12D and FIG 9A- optical arrangement shown in FIG. 9D correspond.

[0215] 图13A-13D与图10A-图10D示出的光学配置相对应。 [0215] FIG. 13A-13D and FIG. 10A- 10D shows the optical arrangement corresponds.

[0216] 图7-图10示出的实施方式利用液体透镜单元85来聚焦、变焦和热补偿;液体透镜单元87和88主要用于在y方向偏离的入射辐射的稳定;且液体透镜单元89和90主要用于在x方向偏离的入射辐射的稳定。 [0216] Figure 7- Figure 10 shows an embodiment of a liquid to focus the lens unit 85, zoom and thermal compensation; liquid lens unit 87 and 88 is mainly used to stabilize the deviation in the y direction of the incident radiation; lens unit 89 and the liquid and 90 is mainly used to stabilize the deviation in the x direction of the incident radiation. 可移动的透镜组82主要提供变焦。 Movable zoom lens group 82 main provider. 在另一个实施方式中,可从系统中除去液体透镜单元85,并且所保留的液体透镜单元87、88、89和90可提供变焦、聚焦和稳定性。 In another embodiment, the liquid lens unit 85 can be removed from the system, the liquid lens unit and retained 87,88,89 and 90 may provide zoom, focus and stability. 液体透镜单元85还可由非液体透镜单元代替。 Liquid lens unit 85 can also be replaced by a non-liquid lens unit. 而且,可允许可移动的透镜组82在稳定期间轴向移动,允许所有液体透镜单元的可变曲率半径在稳定期间变化,或允许以上两者。 Moreover, it can allow the movable lens group 82 during a steady move axially to allow all liquid variable radius of curvature of the lens unit during steady change, or allow both. 这可改进透镜系统80的光学性能,特别在稳定期间视场角落处的光学性能。 This improves the optical performance of the lens system 80, in particular the optical properties of the field at the corner during stable.

[0217] 透镜系统80可采用一对液体透镜单元以提供单一方向的稳定,而非利用两对液体透镜单元。 [0217] The lens system 80 may be a liquid lens unit to provide a stable single direction, rather than the use of two liquid lens unit. 例如,当水平方向的图像跳动可忍受时,则可期待减小垂直的图像跳动。 For example, when an image jitter horizontal tolerable, you can expect to reduce the vertical picture beating.

[0218] 在某种程度上,液体透镜单元偏移光轴的尺寸决定液体透镜单元可提供的稳定量。 [0218] In a way, the liquid lens unit size determines the amount of deviation of the optical axis of the lens unit may be a stable liquid supplied. 然而,随着液体透镜单元远离光轴有效孔径直径减小,在一个实施方式中,第一对液体透镜单元偏移光轴的量与第二对液体透镜单元偏移的量不同。 However, the liquid lens unit with an effective aperture diameter decreases from the optical axis, in one embodiment, a first lens unit of liquid of different optical axis shift amount of the second lens unit liquid amount of the offset. 因为偏移增加,所以第一对液体透镜单元可提供垂直方向的较大稳定,而因为相对光轴的偏移量减小,所以第二对液体透镜单元提供在水平方向上较小的稳定但是较大的孔径。 Since the offset increases, the first lens unit may provide a liquid of greater stability in the vertical direction, but because the relative offset of the optical axis is reduced, so the second lens unit to the liquid in the horizontal direction to provide small but stable larger pore size.

[0219] 可使用不同类型的传感器检测透镜系统的移动。 [0219] may use different types of sensors to detect movement of the lens system. 例如,可使用角速度传感器、压电陀螺传感器、加速度传感器或光检测传感器来检测移动。 For example, the angular velocity sensor, piezoelectric gyro sensor, an acceleration sensor or a light sensor to detect movement. 通过引用并入本文的美国第6,092,700号专利公开了检测移动的系统的示例。 Incorporated herein by reference, US Patent No. 6,092,700 discloses an example of a system to detect movement.

[0220] 移动传感器将信息提供至确定液体透镜单元85、87、88、89和90的适合的曲率半径的控制器。 [0220] mobile sensors will provide information to determine the liquid lens unit 85,87,88,89 and controller 90 suitable radius of curvature. 控制器还确定透镜组82的适合位置。 The controller also determines the position of the lens group 82 is suitable. 通过引用全文合并与此的公开号为2006/0045504的美国专利申请,公开透镜系统的控制器。 Hereby incorporated by reference in this Publication No. 2006/0045504 U.S. Patent Application, Publication lens system controller. 通过引用全文合并与此的第6,987,529号美国专利公开控制透镜系统的另一示例。 Hereby incorporated by reference in this U.S. Patent No. 6,987,529 discloses another example of the lens system control.

[0221] 可预先确定用于控制液体透镜单元半径的适合的电子信号的电平,并将其置于查找表中。 [0221] can be determined in advance for the level control of the liquid lens unit radius suitable electronic signals, and placed in the lookup table. 可选地,模拟电路或数字电路和查找表的组合可生成适合的信号电平。 Alternatively, analog or digital circuitry and find the combination tables can be generated for the signal level. 在一个实施方式中,用公式确定适合的电子信号电平。 In one embodiment, with a formula to determine the suitable electronic signal levels. 沿着多项式的点可被存储在查找表中,或多项式可由电路实施。 Along polynomials point may be stored in a lookup table, or polynomial by circuit implementation.

[0222] 虽然附图示出了变焦透镜的图像稳定,但是图像稳定还适合其他辐射控制装置, 例如固定的聚焦透镜、变焦透镜、畸变透镜、光中继系统等等。 [0222] Although the drawings illustrate an image stabilization zoom lens, but also for other radiation image stabilization control apparatus, e.g., a fixed focus lens, a zoom lens, the lens distortion, optical relay system, and so on.

[0223] 液体透镜单元还可与其他光学元件一起组合使用以实现稳定。 [0223] Liquid lens unit and other optical elements may be used together in combination in order to achieve stability. 例如,将液体透镜单元与棱镜成对使用以改进稳定性能。 For example, the liquid lens unit and the prism pairs to improve stability. 透镜元件的移动可导致传感器上图像位置的移动、 传感器上图像的倾斜或离心移动。 Moving lens elements may cause the sensor to move the image position, tilting or centrifugal movement of the sensor image. 液体透镜单元可用于补偿传感器上图像的移动,且其他透镜单元可补偿离心移位或补偿倾斜和离心两者。 Liquid lens unit can be used to move the image sensor to compensate, and the other lens unit shifts to compensate for centrifugal or compensate both tilt and centrifugation. 传感器可具有额外像素,以及移动检测算法、加速表或陀螺仪,这些可用于确定像素上图像的位置并因此补偿图像移位。 Sensors may have additional pixels, as well as motion detection algorithm, accelerometer or gyroscope, which can be used to determine the position of the pixel of the image and thus compensate for the image shift.
