技术领域 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 the lens element in the optical imaging system, and particularly relates to apparatus and method for a lens element comprising a deformable.

背景技术 Background technique

[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] for example is applied to the variable focal length lens and a conventional multi-lens zoom lens of one or more non-deformable (i.e., rigid such as glass and polycarbonate) of the lens element, which force is typically provided by the motor moves 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, motorless lens element in response to the electric field of the optical system has attracted growing attention of researchers and designers. 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。 A motorless lens element in response to an electric field type is "fluid lens" lens element, which generally includes one or more filled with rigid or flexible fluid film refractive index greater than 1. 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 designers of optical systems, they are generally considered conventional solid lens element system and the motor assembly is bulky and energy consuming. 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 proposals for fluid lens elements, various methods have been proposed for modifying the optical properties combined into a fluid lens element in 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 suggested fluid lens element, the optical characteristics of the lens element may be selected for changing the recommended item is classified into two major types: electrical and wetting 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] The wet processing power, providing a fluid lens element having at least two immiscible fluids 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 at least two fluids is 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] The process fluid injection, the fluid pump is provided adjacent to the lens element, and withdrawing the fluid from the pump into the inside of 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 and out into 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 electrowetting fluid and for changing the optical characteristics of the fluid on the lens elements of the injection method problems have been noted. 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 electrowetting, a problem has been noted in the past, with the current repeatedly flows through the lens element is easy to change the time characteristics of the lens element, so that the use of any system in which the lens element is unreliable and 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 proposals for involving electrical noticed another problem is that electrowetting routinely involves providing two 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 coefficients between the small difference between the two fluids, when 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] with respect to the fluid injection method, for providing such a fluid into the 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 suitable system such that the manufacturing cost and miniaturization is difficult to obtain acceptable.

[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] Because of the problems noted regarding both used to change the optical characteristic of deformable lens element and the electrical wetting fluid injection method, almost all commercial designers continue to rely on the traditional design of the optical system of the motor rigid lens driving system configuration of the optical elements. 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, the driving element can achieve a rigid lens is minimized and energy in the motor assembly with the optical system 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] Briefly, the fluid lens, sometimes referred to as adaptive lens, comprising an interface between the two fluids having different optical refractive index. 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 guided to be spread in a desired direction. 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。 Thus ,, the optical characteristics of the fluid lens, the lens is used, for example, a diverging lens or as the converging lens, and its focal length, in response to an external force applied thereto 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] using an electrical signal to control the operation of the fluid lens fluid lens technology has been described in Matz various names, US Patent No. 2062468; Berge et al., US Patent No. 6,369 d 4; Onuki et al., US Patent No. No. 6449081; Tsuboi et al., US Patent No. 67 (^ No. 483; Onuki et al., US Patent No. 6806988; Nagaoka et al., US Patent application No. 2004/0218283; Takeyama, et al. patent, US Patent application No. 2004 / No. 0228003; Berge, US Patent application No. 2005/0002113 and international Patent application No. WO 99/18546, in WO 00/58763, and No. W003 / 069380.

[0013] 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)、在可重新配置的透镜中使用弹性体材料(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)。 [0013] Other method for controlling fluid lens operation includes the use of liquid crystal material (Nishioka, US Patent No. 6,437,925), the use of pressure (WIDL US Patent No. 6,081,388), the use of elastomeric material (Rogers in the lens may be reconfigurable US Patent No. 4,514,048), and use of micro-electromechanical systems (also referred to in accordance with the first letter MEMS) (Gelbart in US Patent No. 6,747,806).

[0014] 开发流体透镜控制模块的其他尝试可以参见,例如Msaya等人的US专利第6188526号、de Luca等人的US专利第3161718号、Flint等人的US专利第2300251号、 Yao等人的US专利申请第2005/0014306号、Connor等人的US专利申请第2005/0100270 号、Massieu 的US 专利申请第2005/0218231 号、Michelet 的US 专利第4289379 号、 Viinikanoja的US专利第6936809号;欧洲专利申请EP1674892A1 ;英国专利说明书GB1327503 ;日本专利第JP2002243918 号(Olympus Optical 的申请第JP20010037454 号); 和国际专利申请公布第W003/071335号中。 [0014] Other attempts to block the development of the fluid lens control can be found, e.g. Msaya et al US Patent No. 6188526, de Luca et al., US Patent No. 3161718, Flint et al., US Patent No. 2300251, Yao 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 present system, there is a continuing need for a system and method for improving the use of fluid lenses.

[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] and a lens system may 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。 A fixed lens and a fixed lens system having a fixed focus and a stationary, i.e., the direction of the optical axis and the focal length is not changed. 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 a 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 lens focal length and / or elements of the optical axis direction of the lens system, the lens system is also fixed.

[0018] 一副普通眼镜就是这样的固定透镜系统。 [0018] Such an ordinary glasses is fixed to the 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 capable of changing its 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。 Since the spectacle lens does not include any additional or other implement 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 be simplified and the telescope comprises two lenses of glass to make 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。 They are rigidly connected to each piece of the telescope housing different concentric portions, where the housing can slide relative to each other to move the concentric portion of the lens closer 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 are fixed, they naturally can not change focal length 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, the overall telescope lens system is variable, since the sliding of the housing part concentrically with respect to each other changes the focal length by changing the distance between the two fixed lens.

[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 deformable in nature, and it comprises any lens system is also deformable in nature. 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。 A fixed lens is generally non-deformable material, such as glass or plastic; or, if the fixed lens material or an elastic deformable composition, which does not include any means for causing them to extend, compression, bending or other deformation or change in shape part of the lens system method. 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 composition, and the desired lens is prolonged, compression, bending or other deformation is possible after the recovery of its initial state, consisting of one or more elastically deformable elements .

[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 forces may be used to provide the force necessary elements deformable lens to change the shape of the 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 technology has been described in Matz 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 Havens et al., US Patent application 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 insulating fluid located in the first chamber and a second insulated conducting fluid composition of the 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 an outer surface of the wall of the insulating 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 is generated, based on the electrowetting principle, change the wetting properties of the conductive fluid with respect to the surface of the insulating fluid in the container, so that the conductive fluid 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 shape is changed at the interface between the two fluids, the focal length is obtained, the focus lens, or a change 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 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 force transmission of the deformable membrane. 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, e.g., a piston, to push the fluid into the film or the film will be drawn from 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 primary fluid chamber or withdrawing fluid from the primary chamber, the primary chamber and the transfer film is strong; and may be mechanical element affects the force moving the fluid 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 the mechanical force element can be electrically driven, actually applied at the interface so as to change its shape is the mechanical force.

[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 method for controlling fluid lens operation includes the use of liquid crystal material (Nishioka, US Patent No. 6,437,925), the use of pressure (WIDL US Patent No. 6,081,388), the use of an elastic material (Rogers, US in reconfigurable lens Patent No. 4,514,048), and use of micro-electromechanical systems (also referred to in accordance with the first letter MEMS) (Gelbart in US Patent No. 6,747,806).

[0024] 开发流体透镜控制模块的其他尝试可以参见,例如Msaya等人的US专利第6188526号、de Luca等人的US专利第3161718号、Flint等人的US专利第2300251号、 Yao等人的US专利申请第2005/0014306号、Connor等人的US专利申请第2005/0100270 号、Massieu的US专利申请第2005/0218231号、Michelet的US专利第似89379号、 Viinikanoja的US专利第6936809号;欧洲专利申请EP1674892A1 ;英国专利说明书GB1327503 ;日本专利第JP2002243918 号(Olympus Optical 的申请第JP20010037454 号); 和国际专利申请公布第W003/071335号中。 [0024] Other attempts to block the development of the fluid lens control can be found, e.g. Msaya et al US Patent No. 6188526, de Luca et al., US Patent No. 3161718, Flint et al., US Patent No. 2300251, Yao et al.

[0217] 可以调整终端1000以便透镜组合500具有多个透镜设置,已经描述了透镜组合500的各种透镜设置可以通过应用力到一个或多个可变形透镜元件来实现。 [0217] Terminal 1000 can be adjusted so that the lens combination 500 is provided having a plurality of lenses, the lenses have been described in various combinations of lenses may be provided 500 by applying a force to the deformable lens element or more is achieved. 在一个特别实例中,终端1000可以具有7个透镜设置。 In one particular example, the terminal 1000 may have a lens 7 is provided. 在每个透镜设置,透镜组合500和由此得出的终端1000可以具有光学聚焦(最佳焦距)的不同平面和不同视场,典型地由参数“半F0V”角来表达。 At each lens setting, lens assembly 500 of terminal 1000 and thus obtained may have different planar optical focus (best focus), and the different fields of view, typically expressed by the parameter "half F0V" angle. 在一个特别实例中,该终端在七个透镜设置每一个的最佳焦距可以由下面给出:L1 =2"、L1 = 5"、L1 = 9"、L1 = 14"、Ll = 20"、Ll = 27"、Ll = 35",其中"L1-L7,, 是透镜设置“1”至“7”。 In one particular example, the terminal of each of the seven lens setting best focus can be given by: L1 = 2 ", L1 = 5", L1 = 9 ", L1 = 14", Ll = 20 ", Ll = 27 ", Ll = 35", wherein "L1-L7 ,, lens is set to" 1 "to" 7. " 每个不同的透镜设置可以有不同关联焦距半FOV角,和名义聚焦平面。 Each different lens setting may be associated with a different focal length and a half angle FOV, and the nominal focal plane. 在一方面,当触发信号保持激活时,可以调节终端1000以根据预定模式在各种透镜设置之间“循环”。 In one aspect, when the trigger signal remains active, terminal 1000 can be adjusted to various lenses disposed between the "loop" according to a predetermined pattern. 在另一方面,当触发信号保持激活时,可以调节终端1000以根据自适应模式在各种确定透镜设置之间来改变设置。 On the other hand, when the trigger signal remains active, terminal 1000 can be adjusted to vary between various lens settings determined according to the adaptive mode setting. 例如,当触发信号保持激活时,终端1000可以根据将使终端1000能够建立聚焦对准透镜设置而不是简单测试每个顺序透镜设置的聚焦程度的模式来改变组合500的透镜设置。 For example, when the trigger signal remains active, terminal 1000 can enable terminal 1000 to establish the focus lens setting, rather than simply the alignment of each test sequence of the degree of focus lens setting lens setting mode is changed to 500 in combination.

[0218] 在另一方面,可变形透镜元件10移动的时序可以是与曝光周期EXPp [0218] In another aspect, the movement timing of deformable lens element 10 may be an exposure period EXPp

[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] FIG. 27 is a flowchart described with reference to the following 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 focusing aligned 确定帧是否聚焦对准可以包括检查图像数据帧的“平整度”。 Determining a frame alignment may include checking whether the focus frame of image data "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。 Frame by mapping the pixel values ​​in the histogram, the focusing is not aligned with frames within a certain range of relative intensity "level" value of the pixel intensity distribution and the intensity distribution is relatively smooth. 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 align the focus frame relative misalignment focus frame, in certain intensity may have a large number of pixel values ​​is incident, and may have a sufficiently low intensity is incident on the other. 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 terminal 1000 at block 1502 to determine the current frame is aligned focusing, the terminal 1000 can proceed to block 1512 to set the lens held in the alignment determined as a focus is provided, 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。 This processing may include, for example, attempt to decode the symbol or frame may be formatted as the output of a single frame, or a video stream as an output image frame is formatted 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 the focus is not aligned with the frame detected in block 1502, in block 1506 of terminal 1000 can be detected in the image data block having 1502 frames of different frame detected focus setting. 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 particular lens setting," meaning a combination of a focus lens 500 disposed in 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 terminal 1000 at block 1504 is determined to be detected in the frame alignment block 1504 is focused, the terminal 1000 can proceed to block 1512 to the lens assembly 500 is maintained at the current setting (the setting subject to determine the focus aligned frame), and processing one or more frames in the alignment provided focusing lens assembly 500 with the determined exposure.

[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 in block 1506 is determined as not in focus aligned in block 1508, the terminal 1000 can proceed to block 1510 to block 1502 based upon a first detection frame and the second frame in the processing block 1504 to determine the focus detecting 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 the estimated effect of changing the lens setting evaluation flatness frame (e.g., the algorithm can be run, in order to have the best focal length shorter than the first setting if the setting by moving the lens from a first setting to a second setting captured frames becomes flatter when [less aligned focusing], then the processing corresponding to the lens setting set to have a shorter focal length than the first optimum 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 alignment of the focus setting is determined, the terminal 1000 provided on the lens assembly 500 is provided to determine the alignment of the focus, and may proceed to block 1512 to process having a time determined by the focus lens setting is set to coincide disposed aligned a frame exposure period. 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 is determined as a focus aligned in block 1508, the terminal 1000 can proceed to block 1512 to the lens assembly 500 remains in the current lens setting, the alignment and focus settings determined in lens assembly 500 with processing one or more frames exposed.

[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 the view of FIG. 28, shown and described for moving the support and coupled to the member 25 of FIG handheld housing 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。 Unbranded form elements of FIG. 28 showing the mobile phone in the form of common elements, such as a cellular phone, or use in a data acquisition applications portable digital acquisition 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 the housing in a similar form, such as a digital camera or a camcorder form elements.

[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 shows a menu 1097, as indicated, the 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 may have different lens setting associated 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, terminal 1000 in response to the method 500 according to the selected lens setting is changed in the configuration being activated by a trigger signal controls the lens combination.

[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 overview of 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 one configuration, the terminal 1000 is circulated between the various lenses arranged according to a predetermined pattern. 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 the configuration 1, a lens is provided from terminal 1000 is changed to a next lens disposed after each exposure period, and then following with the farthest focus setting (L7 of) the frame has been captured, the lens setting is decremented by one. 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, the positive terminal 1000 corresponds to a trigger signal 1202 being activated, terminal 1000 is provided to change the lens according to a suitable pattern. 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 2 entry indicates when a lens setting terminal 1000 may exhibit a change when the automatic focus mode algorithm. 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 associated exposure periods 1 and 2), is disposed forward of the lens. 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, if the frames 1 and 2 indicate that processing is provided a focus aligned L2, then the subsequent frames, for example frame corresponding to EXP4 4, may have a lens L2 is disposed. 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 the configuration 3, the terminal 1000 does not change the lens setting, the lens setting of the terminal 1000 is maintained at a fixed 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, when the terminal 1000 has been known to be used in a fixed position close to the time of symbol decoding view, you can choose to configure 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 in response to the trigger signal is not being maintained in an active state varies lens setting, the lens setting of the terminal 1000 is maintained at a fixed 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。 When the terminal 1000, for example, be used to capture the scene of the object corresponding to the distal frame of image data when the configuration is useful to 4. 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。 5 in the configuration, the terminal 1000 disposed adaptively varying lens, a focus lens is set until it is determined 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 terminal 1000 to capture a still image when a frame of image data, 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。 From Table D corresponding to the horizontal configuration data 5 can be found, the terminal 1000 may process frames 1 and 2 arranged to determine the alignment of the focus, move the focus lens setting to determine the alignment settings, the determination of focus capturing a plurality of frames disposed quasi process 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 captured at a focus setting determines the alignment may be averaged or otherwise processed 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。 6 about the configuration, a configuration is similar to configuration 6, except when operating according to Configuration 6, a lens assembly disposed terminal 1000 is skipped, and before proceeding to the next set, is maintained at the set for each of a plurality of consecutive frames lens settings. 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。 About configuring 7, 7 represents the operation when the configuration of the terminal 1000 performs a simplified autofocus algorithm in which the terminal 1000 simply provided sequentially for each new step of the lens frame, degree of focus frame in each test obtained, and maintaining the alignment of the focus frame is determined as 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 EXP4 on exposure period, when the process having a frame exposure period EXP3, terminal 1000 can proceed to setting of the lens is not aligned to focus settings.

[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 will be explained further herein, for focusing module operable for all of these elements are not required. 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 role as the spacer element, the spacer element may be omitted, when the single fluid-filled element discussed below is provided by the use of the lens, the pressure element may be omitted by the deforming member acts directly on the focusing element, the housing and the container is an important element, the other of those elements can be placed therein, or they may be assembled therein, and it functions wherein the structural element may be other working device or devices 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。 The [0241] boundary element 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 the desired result is applied to the element as a modification of the focusing force of the boundary not subjected to any deformation element, if the element is the elastic boundary so that is sufficient, when both the focusing element is in the maximum deformation when, in response to said boundary element to be transmitted to it without deforming force or energy. 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 boundary element comprises a focusing module, spacer element and the focusing element and the focusing element comprises a deformable membrane and a fluid, wherein the fluid is sandwiched between the film and the boundary element, use element by applying a pressure to the pressure of the fluid onto the focusing element is deformed, either by pressing the film in the direction of the boundary element, or by reducing the fluid in the boundary element and the thin film of between (e.g., by tightening the ring) 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 border element is not deformed, then when the pressure member to exert maximum pressure on the fluid, it should be sufficiently rigidly held 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 boundary element does not deform the module during focusing, requires only the boundary element in this case is not deformed, without the need that 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, may be obtained from the Display Technologies of New York Corning Glass Corning Corning® EAGLE2000 Display Grade, available from Pennsylvania, and state of Duryea Schott North N-BK 7 glass America, Inc. 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。 Size factor may be based, for example, the focusing module requires selecting the thickness of the film, for example, it may be 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 the focus fluid, its performance should be selected by compatibility with other materials used in the stability, to be used in the patient and like factors at the desired temperature. 可以使用光学流体和光学级油,例如光学级矿物油。 And the optical fluid may be used optical-grade oil, such as an 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。 One suitable fluid is an optical type A can be obtained from, Ltd., NJ Cargille-Sacher Laboratories Cedar Grove 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 obtained optical fluid SL-5267 from a polyphenylene ether-based Santovac® Missouri St, Charles's Arch TechnologyHolding Limited. 也可以使用水,例如去离子水。 Water may also be used, such as 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 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 element overall typically optically transparent, wherein one of said boundary element and the focusing element or the outer portion of the at least two translucent or opaque portion is also possible , which surrounds the internal optically transparent.

[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 material of the light transmission module focusing minimizing loss through the boundary element and the focusing element should be selected to have a similar refractive index. 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 boundary element comprises a glass, focusing a fluid film and the focus, we should take into account the different focus fluid and the refractive index of the boundary elements, the focus and the focus fluid 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 by means of a material (e.g. glass) to another material (e.g., oil immersion) will be lost for reflecting more light. 相反,折射率越靠近, 将会损失更少的光用来反射。 Conversely, the closer the refractive index will be less loss of light for reflecting. 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 idealized same 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, such a situation may be different in refractive index 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] may also change the focusing on the deformed region of the thickness of the film, the present invention is activated when the holding 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 index of refraction will reduce the amount of deformation to obtain a given change in focal length 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 to about 1.5 or from about 1.6 to about 1.7 or in a range of, for example, a refractive index of about 1.5 or of about 1.6.

[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 member 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 material may be selected according to the compatibility and applying a force to the deformable element of the expected 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 element itself does not deform it, it should be inelastic 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 required in response to the said pressure element is deformable element change its shape or configuration, it should 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。 The [0252] element is a deformable member made responsive to a control signal by indirectly (e.g., by the pressure elements), or directly change the force applied to the focusing element. 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。 It is particularly suitable as the deformable member is actuated electrically conductive polymer or electrically driven 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 can be obtained by the Menlo Park, California Artificial Muscle Ltd. Electroactive PolymerArtificial Muscle port Wo / or the Universal Muscle Actuator platform, is another example of the driving device by a conductive polymer Company, Osaka, Japan EA MEX obtained.

[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 member is an elastomeric synthetic polymer or electrically actuated, the deformation element similar to provide two or more layers of muscle fibers may be 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。 Further, when the electrical excitation layers deform in response to a specific direction, this effect can be used to select for a given direction of movement of the entire recombination. 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, the requirements may be obtained, for example, in which the layers have a synthetic polymeric elastically deformable element body is mounted to a rectangular solid shape as shown in FIG. 44, but in response to electrical excitation, even if a non-elastic structure limits the movement or direction, or in a special way affect the movement, which may be a rectangular solid as shown in FIG. 45 turned up, the side shown in FIG. 46 extends, bent downward 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。 FIGS. 45 and 47 describe the uneven surface of the rectangular solid, a portion of the rectangular solid, for example, which may be limited by the use of an external frame or other structure (not shown), through a portion of the solid was anchored or secured to the inelastic member , or by including the appropriate selection layer or structure of the solid. 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 solid rectangle may exhibit a constant radius of curvature along its length, e.g., longer curved side formed along a circumference of the circle may represent an 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 stimuli may include less than all of the supply voltage to the circuit, and / or opposite to the polarity of the supply voltage of the circuit.

[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 changes in shape can further be achieved by the layered application or it has a combination of their own electronic control circuit for each of these layer or layers; Alternatively, the deformable member may be of it movement limited in one or more directions, thus forcing and moving in the direction of a desired 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。 A similar effect may be achieved by manufacturing the various layers are not the same size, e.g., in a two-layer structure, if a certain one long dimension than another, then these two layers will be substantially shorter drive in the the bending 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 the reference deformable member shown in Fig. 29, 30 and 36, 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 Figure 36, for example, fingers or by strip-like elements comprises two or more layers 5a polymer to function, 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 the size of the layers or size will cause each finger 5a crimped or bent towards the pressure member, it presses the film to the focusing direction, and this movement will sequentially focusing said film is deformed into a convex lens 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 will substantially bend or move in the direction of the layer or non-deformed.

[0255] 图48和49表示双凸电致动聚合体薄膜透镜。 [0255] FIGS. 48 and 49 represent electric actuator lenticular lens polymer film. 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, the lenticular lens configuration is possible. 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。 Different from the thickness of the material of the film and 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 plurality of deformable membrane assembly of lenses, and it should be noted that the zoom lens can be applied to two (or more) to achieve the lens fixing member and the other member is driven by an electric actuation 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] FIGS. 51 and 52 represent an ordinary lens by arranging an electrically actuated mechanical means in the polymer, plus an additional fixing element can produce variable positioning of the lens element a compact zoom and autofocus 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 deformation 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 deformation element may be transmitted through 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 one example, may be connected to the pressure element or the focusing element in contact with said 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 may contact the outer portion of the member, directly or indirectly focus.

[0259] 所述导体元件传输所述控制信号给所述变形元件。 [0259] The conductor element transmitting 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 response to the deformable electrical element case, as in the electrically actuated polymer case, since it is substantially as a conductor for conducting electrical power to said deformable element from said power source. 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。 Thus it should be a conductive, preferably highly conductive, at least at opposite portions, and may include a conductive material comprising a conductive metal such as copper, conductive plastic, or substituted with a carbon coating a protective layer or coating material to produce the 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 the deformable member.

[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 described in FIG. 29, the conductor element comprises two parts, one side of each of the deformable elements, and each element having an electrical contact for connecting a power source port 6c, in this embodiment the deformation element in response to the presence or absence of an electric signal is uniformly activated or stopped, and the convex meniscus is formed by the focusing element is 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 appreciated that the element may comprise a plurality of conductor circuits selectively exciting one or more portions of the deformable element, so as to allow operation of the focusing element is adjustable by the convex meniscus plate may be asymmetrical to selectively. 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 electrically conductive element. 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, the deformation element by using an insulating material, for example, between the flexible circuit is configured so that each finger (also shown as element 30 in FIG. 5a), or a combination thereof 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] given by the control voltage selecting circuit which, or how much 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。 Herein, the deflection means can be used to configure the meniscus to have a boundary different from that element and perpendicular to the symmetry axis tilt and offset of the possible combinations of shape of the center of the fluid chamber. 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 shows a simple example in which the focus fluid has been further indicated as 3b meniscus element. 3C, is shown having an asymmetrical shape control signal in response to selection of an application (not shown) in a 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] connected to a conductor element is selected to release the deformation element for driving it through the entire desired range of movement of the expected range and the polarity of the power supply voltage.

[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] can refer to the accompanying drawings to further provide a background context for the discussion above, it should be understood that for convenience purpose of this discussion, they are only showing the specific structure of the focusing 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] Specifically, Figure 29 provides an exploded view of one embodiment of the focusing module. 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 member 2 to establish a relationship between the isolation boundary element 1 and the focusing element 3. 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。 4 the pressure element against the focusing element 3, and is deformed effect element 5, which in turn, is the conductor element 6 acts. 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 element 6 comprises two sub-elements 6a and 6b, which is a conductive element, for transmitting electrical control signals to the deformation elements 5. 元件6c 是导体元件6的电接触端口。 6c is an electrical contact element port 6 of the conductor element. 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 on the element ports 6a, but in 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 housing element 7 is, for the environment and for providing said object focusing 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 assembled form of the embodiment of FIG focusing module 29, wherein the housing member 7, the electrical contact member 6c, 4 are most deformable element and the pressure element 5 is visible. 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。 FIG 30 is a perspective view of the assembled focusing module is viewed, i.e. the element closest to the boundary by Figure 29 from the right side of FIG, whereas in FIG. 31, the focusing module is assembled from FIG. 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 may be available depending on the size of the member, it will be arranged or assembled into a user equipment and needs to be 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。 In summary, the focusing module and the cylinder 30 substantially as shown having from about 31 to about 13, 15 or 20mm- 5,7,9mm like large diameter 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。 To maximize or its dimensions may be selected to achieve compatibility with existing equipment, for example, a cellular phone can be photographed, preferably about 9,9. 5, or the diameter of IOmm.

[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 illustration, the description, and 34 each include a boundary element, a focus fluid 3B, focus film 3a, and the deformation elements 5 of the combination 321 of FIG. 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 FIGS. 32 and 34, the minimum pressure is applied to the focus on the fluid 3B, is focused corresponding planar film 3a. 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 FIGS. 33 and 35, the deformation element 5 to focus on the fluid pressure applied 3B, and as a result the focus lens or a film-forming 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 applied to the deformable member 5 substantially perpendicular to the focus plane of the film and the boundary element 3a represented is applied in the direction 1, comprising reducing the fluid chamber focusing its circumference height and thus forcing the fluid to flow from the circumference of the central chamber; this effect can produce menisci recess 33 seen from FIG.

[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 noted previously, the deformable member may act directly or indirectly to the focus 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 deformation 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, a film in direct contact with the focusing, when the focusing element comprises a spacer, and sandwiched films focus focusing wall of the fluid film between the element boundary, defined as having a cavity for receiving the focusing fluid 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 comprises itself 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 FIG. 34, wherein the deforming member 5 is also focused as a limiting wall of a cylindrical chamber 3b of the fluid used, the chamber having a "top" wall 3a is formed by the focus and the film is formed by the boundary 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 5 is applied in the isolation film 3a substantially parallel to the focusing direction and the plane indicated are applied in the direction of the center of the fluid chamber. 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 the deformation 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 member may be accompanied by the deformation of the element height or thickness decreases inwardly, shown in Figure 35, the effective focus films 3a and pressed against the border elements 1 to each other and help forming the focusing meniscus, not only the radial inward movement of the deformation element to force the focusing fluid-filled cylinder of smaller diameter, and the focusing element aggregation film and the boundary of the cylinder is also reduced the height of.

[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, those having a focus module may comprise at least one upper surface 4101 and lower surface 4102, outer walls 4103, 4104 of the volume of fluid inside the cylinder 4100, the cylinder having a diameter d and a 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 external elements of this structure, in order to make a height h and diameter d or all of the reduced, it will exert a pressure on at least one of the driving 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 is incompressible capacity, in which the height and / or a reduced diameter must be compensated by a corresponding expansion volume in a certain direction, in a case where the focusing module, which will cause an upper surface 4101 and a lower surface of one or all of the 4102 modification. 图39和40提供了这种效果的简明的垂直侧面视图。 39 and 40 provide this effect vertical side view of simplicity. 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, FIG 39 provides a highly reduced deformation results in 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 FIG 40 provides a view of the diameter reduction results in 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 necessarily 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 deformable projection from the upper surface 4101 to compensate for it, which are set forth in these respective modifications and changes 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 member may be deformed or apply pressure to the interior of the fluid shown in FIG. 29-35. 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 height may be varied simultaneously, and thus may be used to generate relatively large half-moon, and / or reduce the time required for the meniscus is formed.

[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 some or all of the 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 is a sectional view to illustrate the state of deformation of the annular member 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 deformable surface (not shown) is flat, whereas in the deformation element 42 has passed through in a vertical or "h" in the horizontal direction and an extension or compression "d" direction or elongated 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 deformation element by the upper and lower surfaces painted with the same effect shows up on their entire surface area, 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, directional references such as "horizontal," "vertical" and the like are generally used in a relative rather than absolute sense, for example, on a vertical reference plane is perpendicular to the lower surface and direction of the line defined by the horizontal reference direction is parallel to the plane and lower surfaces defined by a straight line). 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, it is also contemplated that the at least one surface of an edge or surface will be fixed or anchored, when the deformable element changes its size, which will result in different effects. 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, 42, if the upper surface is flexible and the lower surface is constant, and the outer circumference of the cylinder is limited by reference to FIG, for example, contained within the ring of metal, ceramic, or other rigid material, then the moving said deformable material contracted or compressed in the vertical direction or elongated and extends in the horizontal direction will not be uniform and symmetrical, but will result in a funnel shape as shown in FIG. 43, for example, a.

[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 that the focusing module configured to generate a concave lens are equally 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 member may be positioned at the focus film, between the film and the spacer element, and activates the deformable element may increase rather than decrease in the fluid chamber it height around the circumference or outer circumference. 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。 If the deformation element is also used as the spacer 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。 Said pressure member need not exist, the deformable element in its case to focus directly on the film.

[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] Reference Example preparing for, and can be a specific method of filling the fluid chamber of another concave lens. 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. glass plate, for example, is placed in the recess located in the support structure of the metal plate. 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 film or layer disposed on said glass sheet combination element isolation, for example by using known techniques to the rotary PDMS coated to a 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。 The final composition is then a glass plate border element, the spacer element, and PDMS membrane element is placed under vacuum, a fluid focus, 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。 The extent of the selected recesses of the focusing module and to the remaining capacity of the selected parameters, the final module may only by changing the degree of focusing recess element acts, or may be capable of the thin film state from the recess deformation to a flat state, and even deforming it more than a flat state to a convex state.

[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] According to whether the control signal is applied, the deformation element has an activated and a deactivated state, and has a continuous transition between these two states, preferably linearly in response to the length of the control signal. 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 zero or minimum input state of the deformable element, instead of "active" to describe the state of the deformable element when the control signal is applied, the system may be configured wherein one to invalidate the maximum force is being applied to the time of the focusing elements, or minimal force when being applied. [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] Thus, FIGS. 32 and 34 may be referred to represents that the inactive state, the system is configured such that when the control signal is not being used, the deformation element to force the transmission of at least a focus 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。 And 33 and 35 may represent the active state, wherein the control signal being applied to excite the deformation 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, to FIGS. 32 and 34 shows a state when the control signal being applied to the system, and Figures 33 and 35 indicates when the control signal is zero or its minimum intensity status. 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 deformation element may be turned off when the power supply is released (as in FIGS. 32 and 34) or be elongated or expanded when the power is turned off (as in FIGS. 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 module is generally converted to the desired "stationary" state should be in the focusing 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 focusing distance is limited, for example 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。 Thus the configuration of the system state may be focusing on infinity, or closer according to whether the user wishes to "normal" or "stationary" 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] In the case where the foregoing discussion has been presented as a focusing element including a focusing and a focus fluid film, which is also applicable to the focusing element is an alternative embodiment of a case where the whole, as the fluid fills / fill the case of elastomers full of oil. 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 outer surface of the focusing function of the elastic body to provide focusing film, the inner surface of the focusing function of the elastic body to provide fluid focusing.

[0287] 通过操作透镜配置可以实现激光条形码扫描仪。 [0287] Laser Scanner may be achieved by operating the lens configuration. 参见下文图86-88。 Referring to FIGS. 86-88 below. 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。 Without using the current mirror or scanning barcode scanner motor, the fluid lens may be used to implement the easy-to 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。 Spot position of the laser beam width is narrowest at the same time can be the same or different effects due to the fluid lens. 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 portion to be scanned the barcode 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 light receiving system is not shown, 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 it is desirable to develop a single line scan or raster scan line. 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 is also envisioned, but not developed only scan lens optical power 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 the distance 53, the reader of the present invention is capable of operating, or the same, the focal length optical reader may vary, as from the lens to the object to be imaged from the q Variety. [0289] 对于特殊几何位置的焦距可以通过这个方程式确定: [0289] the focal length may be determined by the particular geometrical position of this 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 of the lens, [rho] is the distance from the lens to the surface on which a desired image is observed (e.g., optical imaging sensor or film), and q is between the lens and the object to be observed 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 the reader away from the lens located closer ql and q2 of the two more distant objects (e.g., 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。 In a conventional system is not expensive and configuration, the distance P (from the lens 920 to the imaging sensor 922) are 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, ql we may be located a distance from the imaging lens in the object, we can imaging an object located at the focal length of the lens at a distance q2 given as 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, for a contained can be provided at a fixed value ρ minimal focal Π and maximum focal length f2 of the fluid lens reader, we will be able at least from ql to properly observe the q2 distance of the focused object, without regard to, for example, in problem domain field depth of the lens particularly when the focus setting. 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, for example, 4 inches (closer IOCM) so that we can image the target object (e.g., a high density bar) with more details by converting or decoding all the details present in the object. 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 lower density over longer distances (e.g., per unit of length on the target object or lower region 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, one may include a long-distance (or the two variable limit values ​​in terms of any intermediate case) Special imaging sensor reader is configured to perform the present invention is extremely high density / low density is extremely short or /, by simply controlling the focal length of the fluid lens is advantageous to> d> ql range of expected distance d of the object to be imaged correctly q2.

[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 change its focal length to achieve optimum focus until a given object distance. 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。 A method for performing this is to make a so-called circle of confusion formed by a point or object within the field of view 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 may be performed automatically by the microprocessor, which changes the focal length of the lens and the measurements on a CCD or CMOS imager 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。 The minimum circle of confusion is the best focus and a focal length of the 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 something changes in the field of view, for example, the object becomes farther away from the lens, then detecting a change in the microprocessor and the size of the circle of confusion, and controls the autofocus procedure.

[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 may be inherent in the detail view field, 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 IR laser projection field (the wavelength of the IR sensitivity of the human eye than, but not more than the sensitivity of a 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, such as Fourier transform, and then adjusting the focal length of the lens so that the fluid results of the high frequency portion converts 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 may be used in a similar fashion 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 transform techniques or wavelet techniques are accomplished in a simple best focus by maximizing contrast of pixels in CCD or CMOS image sensor. 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 process, for example to maximize the intensity difference between adjacent pixels, are known in the art and are commonly used in the passive focusing a digital camera.

[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 system for a general-purpose microprocessor various embodiments of the present invention. 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 a target object T, such as the ID and 2D bar code symbol, a combination of illumination 4020; and an image of object T for receiving therein and producing an electrical output signal represents the combination of the imaging optical encoded data 4030; illumination combiner 4020 may include, for example, an illumination light source assembly 4022, for example, one or more lenses, a combination of the illumination optical diffusion member, wedge, elements of these mirrors or 4024-- direction starting from the light source 4022 to a target object T, direct 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。 Illumination combiner 4020 may include, for example, a laser or a light emitting diode (LED), such as a white LED or a 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。 Illumination combiner 4020 may include target illumination and means for projecting the object T on the optical alignment of the aiming pattern 4027. 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 the ambient light level is sufficiently high to determine and allows to obtain a high quality image of the object T, then the illumination combiner 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 may include an image sensor 4032, such as an ID or, CMOS, NMOS, PMOS, CID, or CMD solid state image sensor, in combination with optical imaging 2D⑶D 1034-- play on the image sensor 4032 is used to receive and focus the image of object 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 control module can be transmitted using a command output of the partial frame image data, or an image sensor can be configured with separate addressing of the pixel, easy to implement partial 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。 Using a CMOS fabrication technology, it is easy to manufacture an image sensor pixel so as to correspond to some electric signals of the sensors can be selectively outputted, without outputting the remaining pixels of the sensor corresponding to the electrical signal, thus allowing only the whole image depends only portion of the field of local data associated with the analysis frame. 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 sensor may be obtained from the manufacturer, e.g. 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 C⑶ frame period from the image sensor outputs image data of frame discharge signal can be achieved 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 the signal processor 1035 can be used alone or alternatively the image sensor are 1032-- integrated on a single play of the 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 comprises an integrated circuit 4042 microprocessor and ASIC (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 may also be provided by a field programmable gate 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。 The processor 4042 and the ASIC 4044 are programmable control means, which can be stored in the memory unit 4045 stores a program to be received according to the output and data processing, a memory unit 4045 may include a storage element 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 may 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 memory device. 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。 The processor 4042 and the ASIC 4044 are connected to a common bus 4048 may be any circuit connected to receive and transmit program data, and wherein the operating data, including the address data through a bidirectional bus. 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 the ASIC 4044 in that they are different from each other, how to manufacture and how they are to be 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 information encoded by the symbol encoding, using some or all of the processor and the ASIC 4044 4042 capacity, and includes the necessary hardware, software, and or firmware, which is implemented to extract the required tasks, including tasks extraction the raw data is converted into image information for tasks necessary to decode encoded symbols encoded.

[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 particularly, the processor 4042 is preferably common, shelf VLSI integrated circuit microprocessor which has overall control circuit 55 of FIG., But it takes most of its time to decode the stored RAM4046 the image data and the program data stored in EROM 4047 is. 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 be given over to the function rather than the decoded image data to run, and thus the processor 4042 from the execution the burden of these functions running released.

[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] The processor 4042 and the actual division of work between the ASIC 4044 will naturally depend on the type of available shelf microprocessor, the type of image sensor used, the image data is output at a rate of 4030 imaging composition, 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 work between 4042 and 4044 processors, or even radically for such a 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 the general purpose processor 4042 is sufficiently fast and has the ability to do perform all functions contemplated by the invention, the dedicated processor 4044 may 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。 Thus it is appreciated that the number of processors used and the division of work between them are not 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。 55 of the type shown in [0301] FIG processor architecture, a typical division of labor between processors 4042 and 4044 as follows. 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 a task, for example, decoded image data, which has been stored in the RAM 4046; symbol optical character recognition (OCR) to identify the principle shown in the image data is stored; menu selection process and re-programming functions; process from the control / data input unit 1039 receives commands and data, the control / data input unit 1039 may include a keyboard, such as flip-flops 1074 and 1078 such elements; and providing overall system level coordination.

[0302] 处理器4044最好主要专注于控制图像获取处理、A/D转换处理和图像数据存储, 包括经过DMA通道进入存储器4046和4047的能力。 [0302] Processor 4044 preferably primarily focused on controlling image acquisition processing, A / D conversion processing and image data storage, including storage capabilities through the DMA channels 4046 and 4047 to enter. A/D转换处理可以包括将模拟信号转化为表示为8位(或灰度比例)数字量的数字信号。 A / D conversion process may include the conversion of an analog signal is a 8-bit (or gray scale) digital digital signal. 随着A/D转换器技术提高,数字信号可以用超过8位来表示。 With the A / D converter technology improved, the digital signal can be represented by more than 8. 处理器4044也可以执行许多时序和通讯操作。 Processor 4044 can also perform many timing and communication operations. 例如,处理器4044 可以控制LED 4022的照明,图像传感器4032和模数(A/D)转换器4036的时序,通过包括I/O接口4037的RS-232、例如以太网或其他基于包通信技术的网络、例如USB的串行总线和/或无线通信链路(或其他)发送数据到阅读器4010外部的处理器及从阅读器4010外部的处理器接收数据。 For example, the processor 4044 may control the illumination timing of the image sensor 4032 of LED 4022 and analog to digital (A / D) converter 4036, by including I / O interface RS-232 4037, for example, Ethernet or other packet-based communication technologies network, for example, the 4010 serial bus USB external and / or wireless communication link (or other) data is transmitted to the reader processor and a processor 4010 receives data from the external reader. 处理器4044也可以控制输出用户显而易见的数据到输出设备4038, 例如发声器、优质红色LED和/或可以由例如显示器4082的液晶显示器提供的显示监视器。 The processor 4044 may also control the output of user data to be apparent to an output device 4038, e.g. sounder, the red LED quality and / or may be displayed by the liquid crystal display 4082 such as a display monitor provided. 输出控制、显示和I/O功能也可以由处理器4042和4044之间分担,如建议的,通过总线驱动器I/O和输出/显示设备4037、和4038或许可以被重复,如建议的,通过微处理器串行I/O 口4042A和4042B和I/O和显示设备4037"、和4038"。 Output control, display and I / O functions may be shared between the processor 4042 and 4044, as suggested by the bus I / O output drivers and / display device 4037, and 4038 may be repeated, as suggested by The microprocessor serial I / O ports 4042A and 4042B, and I / O devices 4037, and a display ", and 4038." 正如先前解释的,这种特别的工作分工对本发明来说是并不重要的。 As previously explained, this particular division of work for the present invention is not important.

[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 a processing system comprises adjustable focusing system feedback, such as a system having components as shown in FIG. 53 described herein. 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 begins at step 1110, wherein the command generating captured image, for example by the user pressing the trigger, or in special cases a capture image command issued by an automated system in response, for example, 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。 Once the image captured in step 1110, image focusing is evaluated as indicated by 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 image quality compared with the standard or special circumstances, for example, features in the image sharpness feeling of the edge contrast, 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 metric plane processing using the automatic focusing operation comprising the steps of:

[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, the captured gray scale image (i.e. the capture with a handheld reader and the image resolution of at least 2, or at least four discrete values ​​of the digital image);

[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, optionally gray scale image of the sample (i.e. a line or series of points extracted from the image, or alternatively, if it is an image data corresponding to the addressed pixel is selected windowed frame, the image is sampled image is 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, is created by plotting the number of measurement data points having a particular event histogram gray scale values, e.g. gray scale value represents the X-axis, Y-axis shows the frequency of an event;

[0308] 4、处理该柱状图以提供平面测量作为输出; [0308] 4, the histogram process to provide as an output measurement plane;

[0309] 5、基于该平面测量确定聚焦级别(或聚焦质量);以及 [0309] 5, the focus is determined based on the level measurement plane (focusing or mass); 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, at less than expected from the focus quality metric determines the plane, to change 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 planar image in the column refers to the degree of equilibrium in a different gray scale value 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 distribution with little variation in many different gradation values ​​observed 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, poor image focus flatter than focusing good image, i.e., having an average grayscale value relative incidence over 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 has a high grayscale value of pixels of many, many low gradation value of the pixel, and a number of intermediate gray level values ​​of the pixels. 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 various types of image history information, such as a barcode, the information comprising the encoded information table lookup, or by using fuzzy logic principles provided, it is contemplated.

[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 output of the focus evaluation compared with the acceptable standards, such as 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。 Higher resolution digitized to digital (e.g., greater range defined by the data bits) image can support a more accurate determination of acceptable focus. 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 of 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。 The results showed that when a captured image having an appropriate focus, the program proceeds from step 1130 to step 1150, where the image processing with suitable focusing characteristics, and issue commands to give the user or image capture instrument may be obtained and / or stores the result 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 may command another image obtained then returns to step 1 and repeats the 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 program for operating a feedback system does not include an adjustable focusing system flowchart. 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。 In Step 4210 generates a captured image command, for example by the user pressing the trigger, or by the system automatically issues the command in response to the capture image on certain conditions, for example to sense the position of the object into the 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, corresponding to a first condition, such as a default condition, the first fluid lens driving the lens control signal 920, for example, be used on the lens so that the lens 920 to a voltage near the focus position ql 7 inches to operation 920 . 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 applied voltage is 7 inches from the focus 0 volts. 利用这种聚焦条件,在步骤4220捕获和处理一个图像。 With such focus conditions, at a step 4220 the image capture and processing. 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, the examination information to retrieve from a captured image to determine whether an effective barcode decoding. 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, and the data displayed by the information reporting step is represented by 4260 pairs of the decoded image, and the program stops, 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。 Repeat the subsequent command can be given to the program, perhaps when required 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 the step 4225 determines not achieve good decoding, the program proceeds to step 4230, where the fluid to be applied to the lenses of the lens 920 is adjusted to a first control signal selectable value, for example, cause the lens to be close to 920 30cm focus position of the focusing voltage to q2. 利用这种聚焦条件,在步骤4235捕获和处理一个图像。 With such focus conditions, at a step 4235 the image capture and processing. 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, the examination information to retrieve from a captured image to determine whether an effective barcode decoding. 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, and the data displayed by the information reporting step is represented by 4260 pairs of the decoded image, and the program stops, 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 determined in Step 4240 does not reach good decoding, the program proceeds to step 4245, where the fluid to be applied to the lenses of the lens 920 is adjusted to a first control signal selectable value, for example, cause the lens to be close to 920 q3 IOOcm focus position to a focus voltage. 利用这种聚焦条件,在步骤4250捕获和处理一个图像。 With such focus conditions, at a step 4250 the image capture and processing. 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, the examination information to retrieve from a captured image to determine whether an effective barcode decoding. 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, and the data displayed by the information reporting step is represented by 4260 pairs of the decoded image, and the program stops, 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 bar code is not yet completed, the process returns to step 4215, and repeats the process to 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, but the output is not successful after a certain number of iterations or a predetermined cycle has occurred, or after a certain predetermined time or may be terminated by the program management control device, which in some embodiments may The 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 may stop. 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 procedure is described in Figure 57 uses three discrete conditions to drive the lens 920 to focus the search for appropriate conditions for the user as part of the 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 procedure in which a focal length at a predetermined distance or a predetermined percentage change. 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 evaluation information (or described above), or obtained from the decoded quality information (e.g., whether the information totally out of context or improperly formatted, or close to the effective number determined). 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 (for example, not the distance measurement accuracy of 30cm to 30. OOOcm, but only 30cm is accurate to one-tenth of decimeter). 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。 But rather the test is such that the lens is sufficiently operating in a 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 practical applications, measuring distances were not as accurate 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] The fluid lens may have errors, errors such as spherical and / or chromatic aberration. 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, additional lenses may be used, for example, a positive lens or a negative lens, for example, be connected to the focusing lens module 920 to correct spherical surface, or a higher state of color error. 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 may be selected to compensate for the optical structural material introduced by the fluid lens imperfections or errors.

[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 are applied to create a two-dimensional displacement fluid lens, wherein the horizontal and vertical offset angle is determined by 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 a known circuit is called "accumulation circuit" in analog circuit design, digital design principles and applications by the use of a digital controller, for example, generate such a signal based on the controller, and a digital microprocessor, including adjustment signal Vf and the superimposed signal to generate a control signal suitable fluid lens. 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 Figure 72, the surface of the fluid lens M45 are shown as having shifted in the vertical direction due to the applied signal indicative of Vl and V3 dv caused. 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 fluid lens optical axis of the display does not shift the rotation axis of the lens substantially along the fluid, and the offset adjustment of the optical axis of the male or displayed by a dotted line, which is asymmetrical about a rotational 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 focusing focal length to provide a desired optical power, but is filled with an optical axis correcting means for adjusting said hand movement or hand shake. 在其他实施例中,其他应用是可预期的。 In other embodiments, other applications are contemplated. 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 focus of the lens to a very small value (e.g., operating as a lens having a wide field of view and depth of field of view of the "fish-eye" lens) and using the optical axis inclination adjustment for field of view certain features that are of interest to the field of view 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, characterized in that the center of the field of view when viewed with respect to the edges of the field with minimal optical distortion, the object of interest with reduced distortion can be 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。 Further, a fisheye lens is typically in the object expand the edges of the field, so that such operations may increase the number of the object of interest in the plane occupied by the image sensor pixel, thereby enhancing the details may 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] Further, as has been noted, the difference may be introduced from the outside, for example, the applied voltage, applied pressure, or around, and a temperature around or applied acceleration forces. 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 may lead to individually and mix a fluid lens slightly different than the operation of the same nominal fluid lens. 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 this difference in operating conditions, the lens control signal is substantially the same as the fluid used in the two lenses in each lens will result in different operation 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。 Further, there is provided a simple method of calibration or ready to be applied to the fluid lens may be calibrated so that each of the lens and the lens to provide suitable fluid for each lens control signal to operate in a desired manner belonging to the special conditions in 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 for providing predetermined calibration capabilities relate to the operation fluid lens Over time variation. 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。 Operation of each lens is dependent on the fluid component of the fluid lens chemical, mechanical, and electrical properties of one or more of its properties change over 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 electric signal in the fluid lens may be subjected to one or more electrochemical 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 the heating process, the fluid may change the performance 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, calibration of the 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 an inertial devices such as accelerometers to determine the direction of the fluid lens, which direction information is used to self-calibrate 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。 Gravity and other acceleration forces can cause the fluid to move and change in shape of the free border, or boundary of 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 the two fluids having different densities of the fluid lens slightly. 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。 Means that two fluids of different densities will proportionally the same volume of different quality, because the 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。 Accordingly, because the force (F) = mass X acceleration, the same volume of the two fluids in the case where the same is subjected to acceleration forces slightly different, for example, gravitational acceleration applied to the support or on the outside of the fluid container two 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。 One result of this acceleration may be subjected to a change in relative position of the fluid as a result, the change in shape of the contact surface between the two fluids defined 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 applied acceleration will also affect the reaction of 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, it is applied perpendicular to the plane of the interface between the two fluids acceleration than parallel to the interface between the positive Qieshi Jia two fluids planar member having 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 generally the acceleration force may be applied at any angle with respect to the interface between the two fluids, so the exact direction of acceleration in response to the force applied depending on the aspect, having 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 and the inertial sensor is determined as the position of the object in the tracking time may 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 force applied, the direction of object recognition, and this inertial sensor 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。 Calculating or modeling of the fluid present in how to respond to operation of the lens on the lens the forces are possible through the knowledge of the direction of the fluid lens and the external force comprises gravity. 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。 As described above may be presented understood to describe a linear acceleration forces such as gravity, and performs tracking with nonlinear force of the fluid component, having a rotational force component, or calculated response time varying forces 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, using a suitable sensor adapted to a variety of forces, we can relative orientation between the applied force and to determine 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 the calculation, timely provide information for restoring force applied. 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 necessary as a function of time, a desired deformation of the fluid interface can be canceled. 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 sensor, which is operated 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。 Having the response speed 10000HZ accelerometers located from 4145 N First Street, San Jose, CA 95134 the Crossbow Technology Limited obtained.

[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 lens operation of the fluid to provide a chromatic aberration for example, a vibration of the lens distortion, 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 chromatic aberration correction. 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 already explained above, the use of acceleration forces of example, the fluid lens may be subjected to various distorting forces in some embodiments, or cause the regression of the fluid lens, which is in operation, the 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 inherent integrity of such imperfections or higher order chromatic aberration. 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。 Analysis of various methods such optical integrity is not possible, for example comprising 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 the optical member under test by using a calibration image of the integrity of the system software. 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 examples, the test system is calibrated in some embodiments is a system or device suitable for use in the field, if necessary, so that it can not be familiar with the art in the test chamber is arranged in the optical test all combinations to facilitate effective The method of performing a calibration cycle.

[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, which provides a known applied input signal I (s) is measured and the observed output signal O (S). 被观察的传输函数Hobs (s) =O(S)/ I(S)被确定。 Transfer function Hobs (s) = O (S) / I (S) to be observed 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。 Then be HobS (S) and 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 perform as expected, here C (S) HobS (S) = H (s), or C (S) = H (s) / Hobs (s) 0 Once the correction factor is determined or relationship C (s), it (or in the time domain it Alternatively equivalents) may be applied to drive the lens so as to reduce the imperfections in the fluid are not observed or more integrity. 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 mathematics program, digital filters and filtering methods, and the required processing can be detected, analyzed and calculated, and corrective action can be applied to a circuit (or including both hardware and software) are described in a number of about real-time digital signal processing article. 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 digital signal processor hardware available from many suppliers in the business.

[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] Applications include fluid lens thereof in one or more types of camera used, for example, a cellular phone camera, used in high-quality digital camera, such as those having a high multiple of the zoom lens of the camera, as well as AF can be provided, and pan, tilt, and zoom use ( "PTZ") of the camera. 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 is sweeping the camera moved, 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。 Vertical movement of the camera is inclined, 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。 Commercially available using the camera and its lens refocusing mechanically commutated PTZ video or digital cameras are known, and are 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 a tilt or pan, we need to make two optical interfaces between dissimilar compatible with the fluid to be repositioned from its original optical axis horizontal (tilt) direction (pan) direction perpendicular to the original, or , the fluid lens, can be used to reposition two axis simultaneously horizontal and vertical directions in a single angular direction re-done. 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 calculation such as coordinate readily re-direction, but may be an arbitrary coordinate system comprising a two-dimensional map with three-dimensional coordinates to the coordinates, for example, conventionally in the X-ray crystallography to do so by way of 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。 All a complete autofocus, pan, tilt, and zoom method is the application of a plurality of components in a single device. 自动对焦和变焦已经在上文描述。 Auto-focus and zoom 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。 At least one electrode and the at least one second electrode by providing a first plurality comprising a first electrode or the second electrode of the at least one electrode pair and the voltage applied to the first plurality of light such that when a fluid with respect to the lens when the shaft is measured between a voltage is applied, resulting in the surface shape of the interface between the two fluids in the fluid causes the lens to change the asymmetry measurement can be completed pan and tilt, or more generally, to the optical axis is not a new reorientation direction collinear with the original 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。 Generally, in order to provide complete asymmetric, voltage is applied to the member comprises an asymmetric, and / or applying a voltage to the electrodes will be positioned on the geometric positional relationship asymmetry. 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 in the fluid, the fluid will be a reaction mode to adjust the voltage gradient across the interface as possible to equilibrium, comprising causing said fluid not occupied by symmetrical shape of the interface component, and so as to guide the light along an optical axis and the optical axis new present before the application of voltage is not collinear.

[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 be described for starting the fluid lens is an example of useful 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 as a monopole 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 a bipolar power supply which is capable of providing a voltage between + V1 / 2 to -V1 / 2, the bias is increased by + V1 / 2 volts, resulting in this range from 0 V (= + V1 / 2 volt bias + [- V1 / 2 V] supplied) + Vl to V (= + V1 / 2 volt bias + V1 / 2 volt supply) extend, or alternatively by increasing the bias -V1 / 2 V when, from this range results in -Vl volts (= -V1 / 2 volt bias + [- V1 / 2 V] supplied) to 0 V (= -V1 / 2 volt bias + V1 / 2 volt supply) extends. 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。 Adding the two voltages is easily accomplished by the adder circuit, which are well known in many variations. 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 on the fixed voltage supplying operation. 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 the command of the microprocessor control by setting a switch, the bias voltage supply is configured to provide a plurality of voltages is defined. 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, a digital-analog converter defined code control 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, using a chain of pulses having a controllable frequency as the control signal, the supply voltage can be applied, using a frequency-to-voltage converter which is controlled, for example, the National Semiconductor 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 the electrochemical reaction within the fluid lens at a sufficiently high voltage application is operable such that the single supply electrode 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, there is provided with a power supply is supplied from volts to hundreds of volts level voltage signal of the positive and negative peak voltage. 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 square wave generated by the driver integrated circuit providing an output voltage, for example, commonly used to operate the EL lamp, for example, it 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 schematic block diagram showing an exemplary circuit 400 driving the fluid lens. 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 2900 is supplied by a battery powered, typically run in the range of 3 to 4.5 volts, although other voltages can be designed from the fixed wall and the battery-operated power supply with a circuit operation. 电压参考四20被提供,其具有与低压降电源调节器关联。 Four voltage reference 20 is provided, which has a low pressure drop associated with the power regulator. 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 a pulse train) in the form of a digital input signal and a data line 30 to the four I2C serial interface for the driver circuit is controlled by an external device, such as a microprocessor 4040 in FIG. 55. 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 four serial interface 40 communication with a controller 30 (e.g. a commercially available microprocessor) for adjusting the fluid lens driver circuitry 400, used to set the output frequency of the oscillator 60 four, the number used to set the output voltage analog (DAC) converter 50 is activated four. 提供来自电压参考四20的参考电压给该DAC。 Providing a reference voltage from the voltage reference 20 to four of the DAC. 在一些实施例中,该DAC是10位DAC。 In some embodiments, the DAC is 10 bits 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 the four oscillator provides four timing signal 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 the signal from an external from a suitable source 62 conveyed four, four controller 40 may be designed to enter a power saving state, four external source 62 in some embodiments may be a user or 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。 The controller is generally contemplated herein is any microprocessor-based controller, a microcontroller, the memory and programmed instructions associated with the microprocessor, or 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 80 generates a square wave signal four bridge output driver 45 is four. 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。 The application controller 40 through the four 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 setting the output voltage of the high voltage generator 70 so that the four-level output voltage is proportional to the DAC2920, and is thus configured as a digital source such as a computer is controlled with high accuracy. 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, a suitable feedback circuit is included in order to maintain the output voltage within an input voltage range of environmental conditions and the load circuit part is 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 from a high voltage generator 70 generates four inputs to four 80-bridge driver. 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 may use four sensors 72 and / or the capacitance of the high voltage is generated. 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, for example 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。 Four bridge driver 80 generates a driving high voltage switching fluid lens 95 and the four signals 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, using the rectifier circuit 58, the output may be applied to the load 95, for example, four of the fluid lens.

[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] outputted to the fluid lens is a voltage signal, which is by the use of wave bridge drive waveform signal from the waveform shaping signal generator. 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., it is "bridge" between the two output terminals). 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。 Such an arrangement allows the voltage swing of the load on the doubled compared to being connected to the load to ground. 接地负载可以具有从零到放大器的输出电压的摆动范围。 Vertical load may have a range from zero to the swing of the amplifier 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 driving two loads such swing can be seen, as can the amplifier may be driven end of the 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。 Since twice the voltage means four times the power, it makes sense to increase the size of the local special instructions battery low supply voltage 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 suitable magnitude and polarity of the reference signal accumulated already described, in order to withstand the voltage by the load pendulum is unipolar, but the positive or negative voltage with respect to the signal amplitude becomes twice. 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 advantage just mentioned voltage have demonstrated in this example, because the power P is given by the relationship between V2 / R or V2 / Z, where V is voltage, R is the resistance, Z is 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 is the same as the voltage swing V v (e.g., from -ν / 2 to + ν / 2, from 0 to + ν, or from -v to 0), the effective power is 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 content of the electrical and mechanical engineering principles are familiar explicitly recited as the reference voltage of the electrical system (e.g., ground potential) may be selected in a random manner, only a reference to a different reference voltage to the transfer applications the fluid lens should not alter the fluid lens allocated to the 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 be considered, it should be appreciated that different electrochemical reactions occur can be configured (or may be prohibited), depending on whether the voltage is applied with respect to the reference voltage is a positive voltage threshold, or a negative threshold voltage (e.g., at a particular polar chemical system may 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] FIGS. 84 and 85 is a molded LED 3010 emits energy through the fluid lens 3020 in the positive direction in FIG. 该发射光的发散被用所述流体透镜修正。 The 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 FIG 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。 The fluid lens emitted light may be considered to be close to collimated light, divergent light is emitted even in the example shown in FIG. 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 curvature of the fluid lens is 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 FIG 85, the fluid lens power has been reduced to nearly zero so that the divergence of the light emitted from 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。 Light pattern in FIGS. 84 and 85 indicates that the comparison of such systems may be used to control the coverage of the target of interest (on the area), such as a barcode of interest for use in hand-held reader or imager to read . 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 may be used on one or more windows to protect the scanner or the optical lens system comprises the fluid 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 that, although the details may vary, but the concept can also be applied to package LED, to be applied to the fluid lens may comprise for example, a combination of spherical, aspherical, additional optical elements 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 effectively utilize a greater portion of the light emitted by 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。 For example when the observer close to the imager bar code, in order to determine with greater barcode pattern is illuminated, a desired extending over its entire illuminated more divergent pattern, a bar code and when looking at a greater distance from the imager more converging illumination pattern may be desirable, in order to illuminate not fall outside interest due to the optical domain while being 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] FIGS. 87, 88, and 89 denotes a laser scanner includes a laser 3110, a collimating lens 3120 and the lens 3130 of FIG fluid in various configurations. 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。 Light beam emitted from the fluid lens 3130 focuses the light beam having the narrowest width in the plane of the fluid from the lens 3140 is located a first distance Dl of 3130. 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 light beam emitted from the fluid lens 3130 is focused on a plane located from 3141 to 3130 the fluid lens having a second distance D2 of the narrowest beam width, so that D2 is greater than D1, and when a focal length of the fluid lens 3130 the first main beam direction is not changed when it is 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 power, a 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 FIG 88, the light beam emitted from the fluid lens 3130 focuses the light beam having the narrowest width in the lens 3130 is positioned away from the fluid measurement corresponding to the first distance Dl second primary beam direction in FIG. 86 along a plane 3140, but since the beam 88 is emitted at an angle, the lateral distance of Li beam is "off-axis" a. 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 activation fluid and other optical magnification lens 3130, and the focal length of the main beam direction can be achieved.

[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] object of the present invention is to utilize the advantages of the zoom lens optical system fluid. 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。 The zoom lens configuration of fluid may be used in bar code scanning to enable imaging at various distances from the bar code scanner at different barcodes. 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 scanner, by reducing the lens aperture to increase the depth of the member in the optical domain, generally to 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 disadvantages: first, when the lens is reduced to be smaller, the optical system point spread function so as to increase the scanning element using a narrow strip pattern 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 so as 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 requirement of an operator holding the stationary reader longer period 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 movement of the opponent barcode scanner has a 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, since it takes a long period of time, users will be more likely to be 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 distance to an object or a range of 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。 Lens system can be implemented using a fluid 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 of a plurality of the fluid lens is to be focused on a plurality of in-focus position and best focus position that will be associated with a 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。 Known to cause the fluid through the fluid lens having the lens drive voltage best focused image using a lookup table, and, for that particular fluid lens may determine an operating voltage associated 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 may be calculated and therefore on the imaging device to a given number of pixels associated with 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。 Barcode reader or imager system can be calculated in this case special features such as the width of the object, such as a barcode element width dimensions or package.

[0391] 流体透镜可变部件可以被加到条形码系统中。 [0391] The variable fluid lens element may be added to the bar code 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 member to be used in a part of the optical system, the optical system receives light and allow the system to optimum light efficiency return point spread function 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 having a large depth of field, but is disadvantageous that the amount of light passing through the system is reduced (i.e., less light through the system) and the point spread function ( the minimum resolvable element can also be proportional to the size) 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, the system configuration is provided with a bar code desired optimum amount of light through the optical system having a beginning, and if not achieved good read, the decoding can be extended to the field of view of the barcode scanner any working depth of field in the barcode pattern, 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 lens is used as a variable orifice. 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。 A method of performing such use includes increasing fluid lens colorant to the fluid at least one fluid so that at least one opaque region of the electromagnetic spectrum in the range of interest, for example, in particular in the visible range of the spectrum are 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。 The fluid power source voltage is applied to the lens from the colorant to the lack of special section of the window opposite to the "bottom" backed 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 oil water fluid lens portion.

[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 is curved, in some examples, 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 thickness of the produced water, which is essentially constant as a function of radius across a portion of the window. 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 varying the applied voltage. 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 voltage of the water absorption of the light by controlling the optical thickness of a determined number of the fluid filter. 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 has light absorption characteristics at specific wavelengths, these wavelengths within the fluid through the filter of the amplitude of the light 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] More than one lens element is configured as a fluid lens, a set of three lenses, for example, because of a combination of lenses, the light color can be reduced in the presence of a single element having a through, 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。 A set of three lenses optimization techniques in the lens design 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, a representative example of the system for a given focal length to optimize any given lens. 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 elements to be optimized lens, when a change happens to the lens surface and the fluid when the operation of a single optical element to change parameters such as the focal length, it is not optimally configured. 通过增加第二流体透镜,所述第一流体透镜和所述第二流体透镜的组合可以被最优化以最小化总的系统误差。 By increasing the second fluid lens, a combination lens of the first fluid and the second fluid lens may be optimized to minimize the total system error. 对于所述第一透镜的不同设置,可以使在所述第二透镜的设置相应改变获得最佳组合。 Different settings for the first lens, can be made in the second lens disposed corresponding change in the best combination. 在这两个流体透镜表面曲率之间的最优化关系,例如表面光学放大率,以及因此还有该控制电压,可以被包含在例如被记录在机器可读存储器内的表中。 The optimization of the relationship between these two fluid lens surface curvature, such as surface optical power, and thus also the control voltage, may be included, for example, it is recorded in a machine-readable table in the memory. 因此对于期望系统光学放大率的任意给定设置,给这两个流体透镜的合适驱动电压可以被设计,以及与被记录值一致地被应用。 Thus for a desired magnification of the optical system in any given set, an appropriate drive voltage to both the fluid lens may be designed, and with the recorded value is applied consistently. 在期望的或有利的地方,通过使用线性或更高阶内插和外插可以提高所述表格分辨率的优点。 Desirable or advantageous in place, by using a linear or higher order interpolation and extrapolation can be improved resolution advantages of the table.

[0400] 本发明涉及包含透镜元件和力元件的透镜模块。 [0400] The present invention relates to a lens module comprising a lens element and the force element. 所述透镜元件包括包含两个表面的可变形构件,例如可变形薄膜,其可以是弹性可变形的,具有两个表面的至少一个与流体力传输。 Said lens member comprises a deformable member comprising two surfaces, for example, the deformable membrane, which may be elastically deformable, having at least two surfaces of a transmission and hydrodynamic force. 属于“力传输”可以被用在这里是因为这两个表面都可以是与流体接触的,尽管仅有一个所述流体可以被用来传输力给所述可变形薄膜,为了选择性地改变所述透镜元件的光轴的焦距、和/或方向。 Belonging to the "power transmission" may be used here because the two surfaces may be in contact with the fluid, even though only one of the fluid may be used to transmit force to the deformable membrane, in order to selectively alter the said focal length of the optical axis of the lens element, and / or direction. (这个流体也可以被考虑为“工作”流体。)因此,“力传输”可以具有这样的含义,传输给所述可变形构件或所述流体之一的力将在另一个上产生充分成比例的响应,其中“充分成比例”简单地意味,所述流体和所述可变形构件是封闭系统的一部分。 (This fluid may also be considered as "working" fluid.) Thus, "transmission power" may have a meaning, a force transmitted to the deformable member or one of the fluid is proportional to the generated sufficiently in the other response, wherein "substantially in proportion" simply means that the fluid and the deformable member is a part of a closed system. 例如,如果大的注射器的针可以被插入到膨胀的气球,而不使它破裂,该注射器活塞移动增加气体进去,或从里面抽取气体,该气球在气球的大小和形状上将产生充分成比例的改变,考虑它的弹性和随着在该气球内的空气压力的改变从增加或抽取的空气产生的力的一部分被反射的实际。 For example, if a large syringe needle may be inserted into the balloon inflated, without breaking it, the injector piston is moved into a gas increases, or withdrawal of gas from the inside of the balloon to generate sufficient proportional to the size and shape of the balloon will changes, consider the actual part of its elasticity and with changes in air pressure in the balloon is increased or generated from air extracted reflected power. 相反,在外界空气压力的改变也可以产生该气球在气球的大小和/或形状上的变化,但是因为该气球和外界大气压不是封闭系统的一部分,因此这种变化将是偶然的和非选择性的。 Instead, the balloon may be a difference in the size of the balloon and or / shape changes in ambient air pressure, but since a portion of the balloon and the outside atmospheric pressure is not a closed system, so this change will be accidental and non-selective of. 在注射器内和在气球内的空气是所述工作流体,相对于外界大气压。 In the syringe and the air in the balloon is the working fluid, with respect to the outside atmospheric pressure.

[0401] 应该注意到,当这种透镜元件的最简单结构包括封闭体积的流体、和具有直接与所述流体接触的一个侧面及直接与环境气体接触的另一个侧面的可变形构件,许多关于这种最基本结构的变形是可能的并且落入在本发明的范围内。 [0401] It should be noted that, when the simplest structure of such a lens element comprises a closed volume of fluid, and a deformable member having a side surface in direct contact with the fluid and the other side in direct contact with the atmosphere, on many the most basic structure of this modification are possible and fall within the scope of the present invention. 例如,所述可变形构件的两个侧面可以是与封装体积流体接触的,但仅一侧将是与工作流体力传输的,而另一侧可以是接触到或仅是朝向一流体体积,其被用同于使可变形构件变形的目的,为了改变所述光轴的焦距和/或方向,例如防止所述薄膜表面的污染物,或作为过滤器、或作为附加光学元件。 For example, two sides of the deformable member may be in contact with the package volume of the fluid, but only one side will be physically transmitted with the workflow, while the other side may be exposed or only a fluid volume towards which It is used to cause the same purpose may be deformable member is deformed, in order to change the focal length and / or direction of the optical axis, for example, preventing contamination of the surface of the film, or as a filter, or as an additional optical element. 或者所述封闭体积包含流体体积和气体顶部空间,用所述气体直接接触所述薄膜而不是所述流体,可能它本身与所述流体通过另一个薄膜隔离的。 Or said enclosed volume comprising a fluid volume and a gas head space, with the gas directly contacts the film instead of the fluid, the fluid may itself isolated by the other film. 针对这种原因,为了包含所述可变形薄膜不直接接触所述光学流体的那些配置,所述薄膜构件与封闭流体体积有力传输的这一侧可以也涉及作为朝向所述流体的一侧。 For this reason, the order comprising a deformable membrane does not directly contact the optical fluid those configurations, the volume of the fluid film and the closure member strong side of transfer may be directed toward one side as the fluid. [0402] 本发明也可以在本发明的描述确定方面涉及“光路”。 [0402] The present invention can also be determined in the description of aspects of the invention relates to "optical path." 在包括光学系统和成像器的成像系统中,如果光轴不被封闭(如被快门、虹膜、透镜盖、或其他),并且如果充分的光可以获得,在任何给定时刻所述成像器将接收在该成像系统外部的某个物体表示的图像。 In the imaging system includes an optical system and an imaging device, if the optical axis is not blocked (e.g. by a shutter, iris, lens cover, or other), and if a sufficient light can be obtained, the imager will be at any given time receiving an imaging system external to the image of the object represented. 当光路沿着从外部物体传播的哪条光线,通过光学系统,到达所述图像传感器时,可以广阔地限定该光路。 When the optical path along which light rays propagating from the external object, through an optical system, reaches the image sensor, it is possible to define the optical path wide. 然而该光路是不需要有界限地包含所有到达所述图像传感器的光线,而是包括其中的一部分,直到并且包括在所述外部物体和所述图像传感器的感应区域之间传播的任何单条光线都沿着的所述路径。 However, the optical path is not required to have all of the boundaries comprises light reaching the image sensor, but includes part of, up to and including any single light propagating between the sensitive region of the external object and the image sensor are the path along which.

[0403] 如前面陈述的,可变透镜可以包含在具有不相似光学系数的两种流体之间的可变形界面。 [0403] As previously stated, it may comprise a variable lens having a deformable optical interface between the dissimilar coefficient of the two fluids. 所述界面的形状可以被由力元件提供的力的应用而改变,以至于通过所述界面的光可以被在期望的方向引导传播。 The shape of the interface may be applied force provided by the force element is changed, so that the light propagating through the guide may be in a desired direction of the interface. 作为结果,可以改变这种透镜的光特性,例如是否该光透镜操作作为发散透镜或作为会聚透镜、它的焦距、和它的光轴方向,大体上通过改变可变形元件,其工作作为在平面、凸起和凹陷轮廓中的所述透镜的至少一个面或表面。 As a result, the optical characteristics of this lens can be changed, for example, whether or not the operation as a light-receiving lens as a converging lens or a diverging lens, its focal length, and its optical axis direction, substantially by varying deformable member, which operates as the plane , projections and recesses of the lens in the profile of the at least one face or surface.

[0404] 所述透镜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。 [0404] The lens element may be a single component, for example, fluid filled elastomers, polymers or plastics, for example, a transparent elastomeric material having elastic resilience oil filled plastic. 可选地,所述聚焦元件可以是具有被夹住或保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 held in having said element and the boundary of the two focusing deformable film between the focus fluid (e.g. water or oil) or a plurality of parts, and in which the focusing arrangement focusing fluid and the film together with the composition of 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 sets Sylgard® thin film, suitable materials would include polydimethylsiloxane, or the PDMS, for example, may be obtained from the Michigan central 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,并且例如可以是从大约0. Imm到大约1mm,例如0.2、 0. 3、0. 4mm。 Size factor may be based, for example, the focusing module requires selecting the thickness of the film, and for example, may be from about 0. Imm to about 1mm, for example 0.2, 0. 3,0. 4mm.

[0405] 该组装好的透镜模块的整个尺寸是不严格的,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。 [0405] The overall size of the assembled lens module is not critical, and may be available depending on the size of the member, it will be disposed, and a user or device needs to be changed into the assembly. 这里为所述透镜模块的大小提供的指南是关于当沿着所述光轴看时,所述透镜模块(不仅仅是透镜元件)截面的主要尺寸。 Guidelines provided herein is the size of the lens module is about when viewed along the optical axis of the lens module (not just a lens element) of the main sectional size. 例如,当所述透镜模块是如图132表示的圆柱体,具有透镜元件5802和外壳5804、当沿着光轴5810看时截面5808是个圆圈,以及较大的截面尺寸将是该圆的直径5806 (由点线表示), 没有较小的截面尺寸。 For example, when the lens module is represented in FIG cylinder 132, having a lens element 5802 and the housing 5804, when viewed along the optical axis 5810 5808 is a cross-sectional circle, and larger cross-sectional dimension will be the diameter of the circle 5806 (represented by dotted lines), not smaller cross-sectional dimensions. 如果该截面是椭圆,当所述透镜元件本身是椭圆并且外壳遵照那样的形状,那么主要尺寸将是该椭圆的主轴。 If the cross section is elliptical, when the lens element itself is so elliptical shape and the housing in accordance with, the major dimension of the ellipse will be spindle. 然而,总而言之,所述透镜模块将具有从大约5、 7、9mm到大约11、13、15或20mm的主要直径。 However, in summary, the main lens module having a diameter of from about 5, 7,9mm to 20mm, or about 13, 15 of. 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,具有大约9、9. 5、或IOmm直径的圆柱形透镜模块是优选的。 To maximize or its dimensions may be selected to achieve compatibility with existing equipment, such as a cellular phone capable of photographing having about 9,9. 5, or the diameter of the cylindrical lens IOmm modules is preferred.

[0406] 当使用聚焦流体,应该出于与其它材料兼容性,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。 [0406] When using the focus fluid, should be compatible with other materials for stability in use, it will be used in the patient and like factors to select the desired temperature its performance. 可以使用光学流体和光学级油,例如光学级矿物油。 And the optical fluid may be used optical-grade oil, such as an optical grade mineral oil. 一种合适的光学流体是可以从美国新泽西州CedarGrove的Cargille-Mcher Laboratories有限公司获得的A型沉浸油。 One suitable fluid is an optical type A can be obtained from, Ltd., NJ Cargille-Mcher Laboratories CedarGrove 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 Technology Holding有限公司获得基于Santovac®聚苯醚的光学流体SL-5^7。 Another suitable optical fluid is obtained based on the optical fluid SL-5 ^ 7 Santovac® polyphenylene ether from Missouri St, Charles's Arch Technology Holding Limited. 也可以使用水,例如去离子水。 Water may also be used, such as deionized water.

[0407] 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。 [0407] When the loss due to refraction, it is desirable that the material of the light transmission module focusing minimizing loss through the boundary element and the focusing element should be selected to have a similar refractive index. 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 boundary element comprises a glass, focusing a fluid film and the focus, we should take into account the different focus fluid and the refractive index of the boundary elements, the focus and the focus fluid of different refractive index film . 折射率越不同,当它企图通过一种材料(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 it is attempted by means of a material (e.g. glass) to another material (e.g., oil immersion) will be lost for reflecting more light. 相反,折射率越靠近,将会损失更少的光用来反射。 Conversely, the closer the refractive index will be less loss of light for reflecting. 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 idealized same herein, and preferably within about +/- 0.001 to 0.1 of, for example, about 0.002. 然而,也可以有这种条件,折射率不同可能是有优点的。 However, there may be such conditions, the refractive index differences may be advantageous.

[0408] 也可以改变在变形区域上的所述可变形薄膜的厚度,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。 [0408] The thickness may also be varied deformable membrane on the deformed region, the present invention is activated when the holding variability, which will form a structure having aspheric characteristics.

[0409] 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。 [0409] selecting a focus fluid having a relatively high index of refraction will reduce the amount of deformation to obtain a given change in focal length 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 to about 1.5 or from about 1.6 to about 1.7 or in a range of, for example, a refractive index of about 1.5 or of about 1.6.

[0419] 在图89和90中示出了可变透镜元件的基本结构,其中所述流体是实质上光学透明的,并且所述可变形薄膜的至少一部分也是实质上光学透明的。 [0419] In FIGS. 89 and 90 shows the basic structure of a variable lens element, wherein the fluid is substantially optically transparent, and wherein at least a portion of the deformable membrane is substantially optically transparent. 所述薄膜包括第一和第二表面,至少其中之一是朝向、或可以直接接触所述工作流体的。 Said film comprises a first and a second surface, at least one of which is facing, or may directly contact the working fluid.

[0420] 在图89中所述薄膜是平的,而在图90中所述薄膜呈现出凸起形状。 [0420] In FIG. 89 the film is flat, and the thin film in FIG. 90 exhibits a convex shape. 该凸起形状可以是起因于从所述工作流体施加正向压力,并且这个压力可能是起因于所述流体腔室体积的减小,或者由于引进附加流体到所述流体腔室。 The convex shape may be due to the positive pressure is applied from the working fluid, and this pressure may be due to a decrease in volume of the fluid chamber, or due to the introduction of additional fluid into the fluid chamber. 然而,如图91和92所示,它也可以通过在所述流体的方向上、用在背着与所述工作流体远处对面的所述薄膜侧面上施加的力按压所述薄膜、或所述薄膜的一部分来实现。 However, as shown in FIG. 91 and 92, it is also possible in the direction of the fluid, with the film on the side opposite the working fluid and the carrying away of the pressing force applied to the film, or the said portion of the film to achieve.

[0421] 图91表示在容器5004内的流体元件5002,其依次放在外壳5006内。 [0421] FIG. 91 shows the fluid in the container 5004 element 5002, which in turn is placed within the housing 5006. 所述透镜元件可以进一步包括支撑或边界元件5008。 The lens element may further include a support member 5008 or boundaries. 应该注意到所有元件存在于给定透镜系统和透镜模块内,其摆放在应该至少是实质上光学透明的所述系统的期望光学路径上。 It should be noted that all the elements present in a given lens system and the lens module, which should be placed at least substantially optically transparent in the desired optical path system. 例如,在图91中,可变形元件5010、流体元件5002、容器5004和支撑或边界元件5008在相应于所述透镜系统的光学路径至少一部分的至少一中心部分都应该是至少实质上光学透明的。 For example, in FIG. 91, the deformable member 5010, fluidic elements 5002, 5004 of the container 5008 and the support or boundary element to the respective optical paths of the lens system at least a portion of at least a portion of the center should be at least substantially optically transparent .

[0422] 可变形元件5010连接到工作流体元件5002。 [0422] The deformable member 5010 is connected to the working fluid element 5002. 力元件5014固定在低部分5016上, 而用高部分5018连接压力元件5020。 Force element 5014 is fixed to the lower portion 5016, and portion 5018 is connected with a high pressure member 5020. 压力元件5020是环、垫圈或相似环形的形式,这里显示为横截面。 Pressure element 5020 is a ring, a washer or the like in the form of annular cross-section as shown here. 加上驱动,力元件5014经过部分5018向下施加力到压力元件5020上。 Plus driving portion 5018 through force element 5014 applies a force to the pressure member 5020 downwardly. 压力元件5020在工作流体元件5002的方向上压下可变形元件5010,产生在图93中所示的凸起部分5022的变形。 A pressure member pressing the deformable member 5020 5010 5002 elements on the working fluid direction, as shown in FIG 93 is generated in the deformed portion of the protrusion 5022. 当力元件5014不被驱动,可变形元件5010的弹性、和/或流体元件5002的流动性将导致所述可变形元件充分地恢复到图91的它的驱动前的形状。 When the force element 5014 is not driven, the elastic deformable member 5010, and / or flow fluid element 5002 will cause the deformable member to sufficiently recover its shape before the drive 91 of FIG. 这里的阐述假设了所述可变形元件在默认状态下是平的,以及所述力元件的驱动导致它出现弯曲表面,但应该容易注意到,通过所述力元件的驱动产生图91的结构,图92能够重新出现所述的默认状态。 Set forth herein assumes that the deformable element is in the default state is flat, and the driving force of said element causes its curved surface occurs, it should be readily noted, the structure of FIG. 91 generated by the driving force of said element, FIG 92 can be re-emergence of the default state.

[0423] 如前面注意到的,所述可变形元件的两个表面通常可以都是平的,并且经常是直接与流体接触。 [0423] As noted previously, both surfaces of the deformable elements may generally are flat, and often in direct contact with the fluid. 例如,一个表面通常可以与周围的空气接触。 For example, a surface may be generally in contact with ambient air. 另一个表面可以与工作流体接触,但在其两侧都使用气体也是可能的。 The other surface may be in contact with the working fluid, but gas is used on both sides thereof are also possible. 实际上,任意组合都是可能的:气体/气体、气体/流体、流体/流体。 In fact, any combinations are possible: gas / gas, gas / fluid, the fluid / fluid. 然而,所述可变形元件的至少一侧可以面对、或接触与例如周围空气相对的工作流体。 However, the deformable member may be at least one side face, or in contact with ambient air, for example, opposite to the working fluid.

[0424] 所述力元件传入力为了使所述可变形元件变形,并且因此改变焦距和/或光轴的方向。 [0424] In order to force the incoming force element said deformable element is deformed, and thus the focal length change direction and / or the optical axis. 本发明的所述力元件可以被布置为对称地并圆周地环绕所述可变形元件的中心轴。 The force element of the present invention may be arranged circumferentially and symmetrically around the central axis of said deformable element. 在本文中,对称不是通过所述力元件的物体位置或定位来确定的,而是通过所述力本身关于所述可变形元件是如何被施加的。 Herein, symmetrical or not by locating the position of the object to determine the force element, but by the force of said deformable element itself on how it is applied. 拿圆形可变形元件作为例子,对称布置的力元件是能够环绕着所述可变形元件的圆周施加连续的力,如在图93中的成型内环面表示的,或能够施加空间上有规律环绕圆周的不连续的力,如图94-96所建议的。 Take as an example a circular deformable element, the force elements are arranged symmetrically exerted force can be continuous surrounding the circumference of said deformable element, such as forming the inner surface in FIG. 93 represents or can be applied on a regular space discontinuous around the circumference of the force, as suggested 94-96. 在图93-96中的每个图中,5030表示所述可变形薄膜的表面,并且定型区域5032表示通过环绕着那个薄膜的圆周所述力元件(未示出)施加力在其上的区域。 Each figure in FIG. 93-96, 5030 denotes a surface of the deformable membrane, and styling region 5032 represents a force applied by the force element surrounding the circumference (not shown) in the region of the film on which the .

[0425] 所述力元件可以驻留在所述透镜元件内侧,或者它可以包括所述透镜元件的一个或多个壁,或者它可以驻留在所述透镜元件的外侧。 [0425] The force element may reside inside the lens element, or it may comprise one or more walls of the lens element, or it may reside outside of the lens element. 这些配置的组合也是可能的。 These combined configurations are also possible. 另外,“圆周的”是指所述透镜元件将具有封闭周长、并且其可以组成完成曲线(例如圆形、椭圆形、蛋形、沙漏形或椭圆形)或完整线段(如三角形、矩形或其他规则或不规则多边形)的事实。 Further, "circumferential" refers to a lens element having a closed circumference, and which may constitute complete profile (e.g. circular, oval, egg-shaped, hourglass, or oval) or a complete line (e.g., triangular, rectangular or the fact that other regular or irregular polygons). 所述周长也可以包括曲线和线段。 The circumference may also comprise line segments and curves.

[0426] 可选地,所述透镜可以是单个元件,而不是工作流体和可变形元件的组合。 [0426] Alternatively, the lens may be a single element, rather than a combination of working fluid and the deformable member. 在这个实施例中,所述透镜是可变形的、光学弹性可变形的、固体的,例如其中至少一部分光学透明的硅。 In this embodiment, the lens is deformable and elastically deformable optics, the solid, for example, wherein at least a portion of the optically transparent silicon. 在图97-98中描述了这个实施例。 This embodiment is described in FIGS. 97-98. 图97描述可变形固体5040的盘,在其上放置着垫圈形状压力元件5042。 97 5040 describe a solid deformable plate of FIG, in which the gasket is placed on the shape of the pressure member 5042. 在图98中,压力已经被施加在压力元件5042上,导致它向下移动。 In FIG. 98, a pressure has been exerted on the pressure member 5042, causing it to move downward. 固体5040不能自由地简单按比例远离所述力的方向移动一例如,它可以放置在玻璃表面上,并且被侧壁圆周的压迫一并且因此压力元件5042向下压到固体5040,导致凸起表面5044的变形。 Direction of the solid 5040 can not be freely scaled simply moved away from the force of an example, it may be placed on a glass surface, and the circumference of the sidewall of a compression member 5042 and thus the pressure down on the solid 5040, resulting in a convex surface 5044 deformation.

[0427] 图97和98仅是阐述性的,并且很多替代方案是可以使用的。 [0427] FIGS. 97 and 98 are merely illustrative, and many alternatives can be used. 例如,取代被向下推, 压力元件5042可以被从所述可变形元件水平下施加的力向下拉。 For example, instead of being pushed down, the pressure member 5042 may be applied from a lower level of the deformable member may be a force to pull down. 或者,压力元件2可以环绕固体1的圆周的至少一部分,并且在压缩或压榨作用下使它的直径变小以形成凸起部分5044。 Alternatively, the pressure member 2 may surround at least a part of the circumference of a solid, it is under compression and crushing action or a smaller diameter to form a raised portion 5044. 通过“固体5040的圆周的至少一部分”,意味着压力元件5042将完全环绕着圆周延伸,但可以具有小于固体5040外壁高度的高度,尽管这是可能的。 By "at least part of the circumference of the solid 5040", 5042 means that the pressure element is completely surrounded circumferentially extending, but may have a height less than a solid outer wall 5040, although this is possible.

[0428] 例如,图99表示一个实施例,其中相对较窄、垫圈形状压力元件5046环绕着所述可变形元件的外壁延伸,而图100表示一个实施例,其中使用了相对较宽垫圈形状压力元件5048。 [0428] For example, FIG. 99 shows an embodiment, wherein relatively narrow, the pressure washer-shaped member 5046 extending outer wall surrounding the deformable element, and FIG 100 shows an embodiment in which the shape of the pressure washer is relatively wide element 5048.

[0429] 下面的讨论参考图101,示出具有活塞5102的透镜元件5100、流体5104和可变形元件5108,表示为三种配置:平的Ga)、凸起的Gb)和凹陷的Ge)。 [0429] The following discussion with reference to FIG 101, illustrating a lens element having a piston 51,005,102, the fluid and the deformable member 5104 5108, as expressed in three configurations: flat Ga), raised Gb) and depressions Ge). 在这个结构中,当活塞5102响应于被供应给马达以驱动该活塞的电能量(未示出)而开始移动时,产生了最初的机械力。 In this structure, when the piston 5102 is supplied to the motor in response to the electrical energy to drive the piston (not shown) starts to move, the mechanical force generated initially. 随后该移动活塞的机械能量被传输到与其直接接触的所述流体,从所述活塞传输到所述流体的力立即遍布所述活塞头。 Then the mechanical energy of the piston movement is transmitted to the fluid in direct contact with, the transmission from the piston to force the fluid across the piston head immediately. 所述力依次通过所述流体被传播,直到它到达可变形薄膜。 The force is propagated through the fluid in turn until it reaches the deformable membrane. 因此,在这种类型系统中,导致所述薄膜变形的机械力通过三个流体区域的传播: 第一区域,所述机械力刚刚产生的地方附近,在这个实例中表示为F1 ;第二区域,通过其所述力被从所述活塞传输经过所述流体并到达所述薄膜,在这个实例中表示为F2 ;以及第三区域,所述流体接触到所述可变形薄膜的地方,表示为F3。 Thus, in this type of system, it causes the deformation of the film by a mechanical force propagating three fluid zones: a first zone, just near where the mechanical force produced, in this example denoted as Fl; second region through which the force is from the film and reaches the piston through the transmission fluid, as represented in the F2 of this example; and a third region, contacting the fluid to place the deformable membrane, expressed as F3.

[0430] 图101表示透镜元件,在其中所述变形力在所述力元件和所述变形构件之间改变方向。 [0430] FIG. 101 represents a lens element, wherein the deformation force is changed in the direction of the force between the element and the deformable member. 如所示的,最初的力传播从5102的面到右边,但在穿过活塞表面和变形构件5108的表面之间的所述流体腔室时必须从横向到轴向变换。 Must transition from transverse to the axial direction such as when the initial force indicated by propagation from surface 5102 to the right, but through the fluid in the chamber between the surface of the piston and deformable member 5108 surface. [0431] 另一个配置,在其中所述力改变方向包括次要流体容器的使用,其被用来添加流体到主要流体容器、从主要流体容器中抽取流体,为了影响所述薄膜的形状。 [0431] Another configuration, in which the force changes direction comprises using a secondary fluid container, which is used to add fluid to the primary fluid container draw fluid from the primary fluid reservoir in order to influence the shape of the film. 在一个实例显示在图102中,其跟图101是相同的,除了附加的密封构件5110,其合并2路、自密封阀(未示出),将所述流体体积分为主要流体容器5112和次要流体容器5114。 In an example shown in FIG. 102, 101 which is identical with FIG except that an additional sealing member 5110, which is incorporated 2-way, self-sealing valve (not shown), the volume of the fluid into the primary fluid container 5112 and secondary fluid container 5114. 活塞5102的移动导致在所述主要和次要容器之间的流体的运动,并且所述流体被加到所述主要容器或从沿半径地所述主要容器抽取到所述可变形薄膜。 Movement of the piston 5102 causes movement of fluid between the primary and secondary containers, and the fluid is supplied to or withdrawn from the primary container to the primary container radial to the deformable membrane.

[0432] 图103显示了一个模拟配置,表示可变形薄膜5120、主要流体容器51¾和次要流体容器5126,其与主要流体容器51M的界面通过包含可密封的2路阀(未示出)的界面5122。 [0432] Figure 103 shows a configuration simulation, showing the deformable membrane 5120, the primary fluid and secondary fluid container 51¾ container 5126, with the primary fluid container 51M interface (not shown) comprising a sealable way valve 2 5122 interface. 移动的力,例如活塞,作用来从次要容器51¾推动流体到主要容器51¾,和/或从主要容器51M抽取流体到次要容器51¾,从而使所述可变形薄膜变形。 Moving force, such as a piston, acting to push the fluid from 51¾ secondary container to the primary container 51¾, and / or withdrawing fluid from the primary container to the secondary container 51¾ or 51M, so that the deformation of the deformable film. 这里使所述薄膜再次变形的力具有在次要容器51¾内的部件和在主要容器51M内的部件邻近界面5122,其相对于所述可变形薄膜是横向的,随后当它从所述界面通过主要容器51M传输或传播到所述薄膜,所述力被纵向地传输到所述可变形薄膜。 Here again, the thin film is deformed in a secondary container has a force 51¾ member adjacent the interface and in the main part 51M of the container 5122, the deformable membrane which is transverse with respect to, and then it passes from said interface the main container 51M to the transmission or propagation film, the longitudinal force is transmitted to the deformable membrane.

[0433] 在可选的方法中,使所述薄膜变形的力对于所述薄膜来说可以主要地或完全地是纵向的,当它从产生的初始位置传播到所述薄膜时。 [0433] In an alternative method, the deforming force of the film to the film, it may be primarily or entirely longitudinal, when it travels from the initial position to the resulting film. 在图101和102中,这可以被呈现出来,通过取所述透镜的水平部分(如所示),以逆时针旋转90度,并且校准它以便所述阀直接与主要流体容器在界面5122直接交流。 In FIG. 101 and 102 which may be presented, by taking the horizontal portion of the lens (as shown), rotated 90 degrees counterclockwise, and the calibration of the valve in order to direct it to the primary fluid container 5122 directly interface communicate with. 然而,这必需以不阻碍光轴的方式被完成,当通过使所述第二容器在直径或截面上比所述第一容器的面小,所述第二容器与所述第一容器连接,并且将所述第二容器偏置在所述第一容器的所述光轴。 However, this is necessary so as not to obstruct the optical axis is completed, when connected to the first vessel through the second vessel in the first container facet diameter or section than said said second container, and biasing the second vessel to the optical axis of the first container.

[0434] 当我们考虑制造这种透镜元件和把它安装在应用在设备内的支架或外壳时的实际方面时,例如图104所示的透镜元件的不规则形状将不是最佳的,对于次要容器将可能意味着另外的加工,活塞的相对复杂的放置或其他用来在主要容器和次要容器之间移动流体的移动力,等等。 [0434] When we consider the manufacture of such a lens element and to install it in terms of the actual time of application within the device holder or housing, such as the irregular shape of the lens element shown in FIG. 104 will not be optimal, for the times to the container may mean additional processing, relatively complex piston disposed for movement force or other movement of the fluid between the primary container and the secondary container, and the like. 这样的结构也可能致使所述次要容器在组装期间和在使用期间更易于破损,依赖于所述次要容器在移动之间可以承受的力的数量,从而损坏或打破与所述主要容器之间的界面,也关于图101和102,它不明显的,我们可以简单旋转所述透镜元件的水平部分来与所述薄膜纵向结合,当所述活塞将随后至少部分地,如果不是完全,妨碍所述光轴ο Such a configuration may cause the secondary container during assembly and more prone to breakage during use, depending on the number of the secondary container can withstand between the moving force, so that damage or break of the primary container interface between, and also about 101 and 102, it is not obvious, we can simply rotate the lens portion to the horizontal longitudinal member bonded to the film, when the piston is then at least partially, if not completely, obstruct the optical axis ο

[0435] 力从它来自所述力元件的起点到它被所述可变形薄膜吸收的吸收点的路径可以是对可变形薄膜横向的,可以是对可变形薄膜纵向的,或者两个的结合。 [0435] It is the starting point from the force from the force element which is to be the point of absorption of the absorption path of the deformable membrane may be a film laterally deformable, and may be, or a combination of two films of a longitudinally deformable . 在本文中,术语“横向”和“纵向”被用来指一条线通过和垂直于所述可变形薄膜的表面,当所述表面是平的(或,如果它不是平的,在中心点或轴垂直于它的表面),“横向”力是垂直或充分垂直于这条线的,而纵向力是平行或充分平行于这条线的。 As used herein, the term "lateral" and "longitudinal" are used to refer to a line perpendicular to the surface through the deformable film, when the surface is flat (or, if it is not flat, in the center point or axis perpendicular to its surface), "lateral" force is perpendicular or substantially perpendicular to this line, while the longitudinal force is parallel or substantially parallel to this line. 可选地,给定一个具有均勻曲率的可变形薄膜,术语“横向,,和“纵向,,被关于所述光轴被使用,“横向,,力是垂直或充分垂直于所述光轴的,而纵向力是平行或充分平行于所述光轴的。在图105中的这样的力的示意性实例,描述圆柱体可变形薄膜的圆形表面5150、中心线5152(其可以被考虑所述光轴,当圆形表面5150具有均勻曲率)、横向力T、和纵向力L。在这个表示中,横向力T对于所述可变形薄膜的圆形表面将是径向的,而纵向力L将是平行或充分平行于所述中心线或光轴的,其是垂直于所述圆并且穿过其中心。知晓本领域技术的人将容易认识到应用到所述可变形薄膜的表面的任何力对于那个可以被分为横向和纵向成分的表面来说不是纯横向或纯纵向的。 Alternatively, given a curvature having a uniform deformable membrane, the term "lateral ,, and" longitudinal ,, been used with respect to the optical axis, ",, lateral or vertical forces are substantially perpendicular to the optical axis , while the longitudinal force is parallel or substantially parallel to the optical axis. illustrative examples of such forces in FIG. 105, 5150 describe a circular cylindrical surface of the deformable membrane, the center line 5152 (which may be considered by said optical axis, when the circular surface having a uniform curvature 5150), T lateral force, and longitudinal force L. in this representation, the transverse force T to the circular surface of the deformable membrane will be radial, and longitudinal force L will be parallel or substantially parallel to the centerline or optical axis which is perpendicular to the circle and passing through its center. its skilled in the art will readily recognize applied to the surface of the deformable membrane for any forces that may be divided into horizontal and vertical components of the surface is not purely lateral or purely vertical.

66[0436] 在用压力元件接触所述可变形薄膜以从所述里元件传输力的实施例中,所述压力元件的大小、形状和合成可以被改变以实现各种目标,包括所述可变形薄膜的表面材料的化学兼容性,它与所述可变形薄膜接触,在所述压力元件和所述可变形薄膜之间的接触点获得最小的摩擦系数来最小化磨损、成本、容易加工、加工精度。 66 [0436] In the contact pressure element to the deformable film from the embodiment in force transmission element, the size, shape and resulting pressure elements may be varied to achieve various goals, including said chemical compatibility of the surface material of the deformable membrane, it is in contact with said deformable membrane, for minimum friction coefficient at the contact point between said pressure member and said deformable membrane to minimize wear, cost, ease of processing, Precision. 接触所述可变形薄膜的在所述压力元件没有边缘毛刺是优选的,也就是,该表面应该不是可以由线来表示,或这不是产生与两个表面的直接交叉,象以矩形固体的边缘的形式。 Contacting the deformable film is not in the pressure element burr is preferred, i.e., the surface should not be represented by a line may be, or it is not a direct two intersecting surfaces, the edges of a rectangular solid as form. 进一步,所述压力元件接触所述可变形薄膜的的所有表面有关是曲线的,不管是否是圆形的,否则其将是两个平面表面之间的毛刺边缘,如图106表示的,显示出,压力元件5200、平面表面5202、平面表面5204、和曲线截面表面区域5206的交叉部细节,或者通过提供所述压力元件全部地具有圆形、椭圆形、蛋形、或抛物线形截面形状的形状,如图107、108、109和110各自表示的,或其他具有不是直线的截面的形状。 Further, the pressure member contacting the deformable thin film is a graph relating to all surfaces, whether circular, which would otherwise be the burr edge between two planar surfaces, as represented by 106, shows , the pressure member 5200, 5202 planar surface, planar surface 5204, and the cross-sectional surface area of ​​the curved portion 5206 details, or with all of the pressure element by providing a circular, elliptical, egg-shaped, or parabolic cross-sectional shape of the shape , 107, 108, and FIG, or having other cross-sectional shape is not linear representation 110 each.

[0437] 所述尺寸和形状也可以被改变以影响所述可变形薄膜响应速度和幅度以改变着两个元件之间的关系。 The [0437] The size and shape may also be varied to affect the response of the deformable membrane to change the speed and magnitude of the relationship between the two elements. 例如,图111和112表示相对窄和相对宽压力元件5302的使用,这里显示为环或垫圈结构。 For example, FIGS. 111 and 112 represent a relatively narrow and relatively wide use of the pressure element 5302, shown here as a ring or gasket structure. 因为在图112中所述压力元件比在图111的覆盖所述可变形薄膜更多表面区域,并且因为所述薄膜是可变形的,在图111和112中所述压力元件同等数量的向下移动将导致图112的所述压力元件产生明显更凸的表面,如在图113和114所示,可选地,如果期望用两个压力元件都生成同样数量曲率或凸度,那么图112的所述压力元件可以比图111的所述压力元件被移动更小的距离以实现相同效果。 Because the ratio of the covering of FIG film 111 may deform more surface area, and because the film is deformable, an equal number of said pressure member downwardly in FIGS. 111 and 112 the pressure element 112 of FIG. movement will cause the pressure generating element 112 of FIG significantly more convex surface, as shown in FIGS. 113 and 114, alternatively, if desired with two pressure elements generates the same amount of curvature, or crown, then 112 of FIG. the pressure member can be moved a smaller distance than the pressure element of FIG. 111 to achieve the same effect.

[0438] 选择重或轻的材料来制造所述环也可以影响所述透镜元件是怎么对给定数量力的输入作出的响应,因为它们比更轻材料会更困难响应于力的应用。 [0438] a material selected heavy or light produced in response to the ring may also affect how the lens element is a force of a given number of input made, because they will be more difficult than in response to forces applied to lighter material. 相似地,所述光学流体元件的速度和/或特别重量可以影响系统对给定数量力的输入作出的响应。 Similarly, the optical element of the fluid velocity and / or the Special weight may affect the system's response to a given amount of input force made.

[0439] 当这里讨论的多个实施例描述最初以纵向方作用到所述可变形薄膜的所述力元件,对于所述力元件最初以切向或径向作用到所述可变形薄膜也是可能的。 [0439] When multiple embodiments discussed herein describe the force element is initially applied to the longitudinal direction of the deformable membrane, initially for the force element acting radially or tangentially to the deformable membrane are also possible of. 例如,不象用压力元件向下压在平坦的可变形构件上以形成凸表面,没有应用任何力构造所述可变形薄膜具有一个凸表面是可能的,并且随后在所述可变形薄膜施加径向向外力为了降低所述表面的凸度,如在图115和116所示的。 For example, unlike the pressure element presses down on the flat deformable member to form a convex surface, without applying any force to the deformable membrane configured to have a convex surface is possible, and then applied to the deformable membrane in diameter to reduce the convexity of said surface, as shown in FIG outward force to the 116 and 115. 图115显示了所述透镜元件的凸表面5312,其是凸的而没有任何力被压力元件5316施加。 FIG 115 shows the convex surface of the lens element 5312, which is without any projections force is applied to the pressure element 5316. 当被驱动,压力元件5304径向向外地移动或扩张拉伸了所述透镜元件的所述上表面和拉平了凸表面5312如在图116中所示的。 When driven, the pressure member 5304 to move or expand radially outwardly of the tensile member on the surface of the lens and leveled convex surface 5312 as shown in FIG 116.

[0440] 压力元件5316和实现这个方法所需的所述可变形元件之间的连接可以以多种方式实现。 The connection between the deformable element [0440] The pressure required to implement this method and element 5316 may be implemented in various ways. 例如,压力环5316可以被粘到所述可变形构件的表面,或被放置在所述可变形构件的内部,以便所述压力元件沿半径向外运动延伸了如示出的所述可变形构件的直径。 For example, the pressure ring 5316 may be adhered to the surface of the deformable member, or placed inside the deformable member, so that the movement of the pressure member extends radially outwardly as shown in the deformable member diameter of. 所述压力元件可以限制在所述可变形构件的上表面的外圆周里的沟槽里,通过环绕在凸部分5312的刚性或至少部分导电环或垫圈型元件支撑在位置上,所述环和垫圈型元件被用作电接触,或作为用来一个或多个电连接的导电,以激励所述压力元件。 The pressure member may be limited on the outer circumferential upper surface of the deformable member in the groove, the convex portion 5312 by surrounding or at least partially rigid conductive ring or washer-type element is supported in position, said ring, and washer type element is used as an electrical contact, or as for the one or more electrically conductive connections, to energize the pressure element.

[0441] 在另一个实施例中,所述力元件可以施加至少部分地反作用力在所述可变形元件上,着可以被用来,例如,减少产生变形的给定变化所需要的所述物体的移动,或增加可以完成给定变形使用的速度。 [0441] embodiment, the force element may be applied in another embodiment at least partly a reaction force on the deformable member, the may be used, e.g., to reduce the deformation of the object is given the desired change movement, or increased deformation can be accomplished using a given speed. 这种配置简化的版本显示在图117中,包括透镜元件M00,其包含可变形构件M02、可变形构件外壳元件M08、和枢纽点M10。 This simplified version of the configuration shown in Figure 117, comprising a lens element M00, M02 comprising a deformable member, the deformable member housing element M08, and a pivot point M10. 所述可变形构件可以是与所述外壳整体成型的或与之连接,例如,所述可变形构件的表面可以是薄膜,其边缘被粘、夹、密封、或贴到所述外壳上,如通过如图118所描述的从在上部分M16和下部分M18之间的薄膜M02的上部分和下部分和密封边缘部分M12构造所述外壳。 The deformable member may be integrally formed with the housing or attached thereto, e.g., the surface of the deformable member may be a film which is glued edges, clamp, seal, or attached to the upper housing, such as described by FIG. 118 on the portion from the lower portion M16 and M02 between the film portion and the lower portion M18 and M12 configured to seal the edge portion of said housing.

[0442] 在这个配置中,安排这样的一个力元件,它的移动将大体上向下压在所述可变形薄膜上,当被图117的上面弯曲箭头建议的,施加大致向下的力在所述可变形薄膜如由成直角箭头所示的。 [0442] In this configuration, a force element arranged such that movement will generally pressed down on the deformable membrane, when the curved arrows 117 in FIG above recommendations, a downward force is applied substantially the deformable membrane at right angles as indicated by the arrow. 另一个力元件被配置以便它的移动将导致所述可变形薄膜的低边缘沿半径向外移动,如由下面弯曲箭头和垂直水平箭头所示的。 Another force element is arranged so that its movement will cause the lower edge of the deformable membrane moves radially outwardly, as shown by the curved arrow below the horizontal and vertical arrows. 这两种移动将比单个地作用力具有更快地整平所述可变形薄膜的累加效果。 Both moving faster than the biasing force individually leveled the additive effect of the deformable membrane. 这也可以被完成使用单个力元件,如所示,以摇杆配置,其中绕着枢纽点MlO的所述力元件枢纽将上臂向下推到所述可变形构件上,而下臂沿半径地向外拉所述可变形薄膜的外部边缘。 This can also be done using a single force element, as shown, arranged in a rocker, wherein the force element about the hub of the arm pivot point MlO pushes down on the deformable member, and the lower the radial arm pull out the outer edge of the deformable membrane. 可选地,所述力元件可以被提供作为两个或多个独立作用元件,其将允许移动的更大控制。 Alternatively, the force element may be provided as two or more elements acting independently, which allows a greater control of movement. 例如如果如图117所示的所述力元件的上臂和下臂是独立可驱动的,所述透镜元件在响应被应用的给定电压时将具有三个可能反应级别,对被应用电压响应的一个给上力元件,对被应用电压响应的第二个给下力元件,而对被应用电压响应的第三个给两个力元件。 For example, upper and lower arms, if the force element 117 is shown in FIG independently driven, the lens element in response to a given voltage is applied to the reaction may have three levels, the response to the applied voltage one for the force element, the force on the second element to the next in response to the applied voltage, and the third to two elements of the force applied voltage response.

[0443] 如在这里别处注意的,所述力元件可以是完全环绕着所述可变形构件的圆周或外周延伸的均勻元件,或可以是多个独立或分散的元件,图119是从所述透镜元件上面沿着所述光轴向下看时,均勻元件的一个实施例的简要表示。 [0443] As noted elsewhere herein, the force element may be completely surrounded by the deformable member is uniform circumferential or peripheral elements extending or may be a plurality of separate elements or dispersed, 119 from the FIG. the above looking down on the lens element along the optical axis, a schematic embodiment of the device showing uniform. 这里M30是所述可变形薄膜的上表面,并且M20表示环绕着所述可变形薄膜的外周的圆形力元件的物理位置,阴影区域5434表示被直接接触所述力元件或从所述力元件接收力的所述可变形薄膜的表面的区域, 例如通过所述力元件的上部分与所述可变形薄膜表面(未示出)的很好定位。 Where M30 is the upper surface of the deformable membrane, and M20 represents the physical position of the circular force element deformable membrane surrounding the outer periphery of the shaded area 5434 represents the force element being in direct contact with or from the force element the area of ​​the surface receiving the force of the deformable membrane, for example (not shown) positioned by a good portion of the force on the element and the deformable film surface.

[0444] 图120表示另一个实施例,在其中所述力元件包含多个分立力元件M50环绕在球形可变形构件MM的圆周上,在所述可变形构件的外表面的连续圆形区域M60上施加力。 [0444] FIG 120 shows another embodiment, wherein the force element comprises a plurality of discrete elements M50 forces around the circumference of the ball may be deformable member of MM, the outer surface of the continuous circular area of ​​the deformable member M60 exerts a force on. 这可以被完成通过适当地配置每个分散力元件接触所述可变形构件的表面的部分,由于在每个这样的部分以圆上的弧的形式与所述可变形构件同圆心和大小的以便在他们之间有很小的缝隙或没有缝隙。 This may be done by suitably arranged portion of the surface of each dispersion member contacting force of the deformable member, since the form of an arc of a circle with the center of the deformable member and with the size of each such portion for in between they have a small gap or no gap. 在这样的配置中,允许在每个这样的弧接触部之间有小的缝隙是必要的,当他们仅停留在所述可变形构件的一个位置上而没有施加向下的力,以至于当它们是弧形的并当被向下压到所述可变形构件时,他们互相不对接。 In such a configuration, allows the arc between the contact portion of each such small gaps are necessary, if they only remain in the deformable member position without a downward force is applied, so that when they are arcuate and, when pressed down to the deformable member, they are not mutually abutting. 可选地,这些接触部分可以是每个是相对小的,但不是直接接触所述可变形构件,如在这里别处描述的它们接触压力元件,并且所述压力元件工作为将从每个力元件接收的相对点类型的力转化为被环绕着所述可变形构件的圆周或外周相对连续施加的力。 Alternatively, each of the contact portions may be relatively small, but not in direct contact with the deformable member, are described elsewhere herein as a contact pressure element, and the pressure member from each of the work force element opposing force receiving point-type force is converted to the deformable member surrounding the circumference or periphery of the counter continuously applied.

[0445] 应该注意许多不是所有这里描述的所述力元件配置可以被调节以放置在所述透镜元件或可变形构件的内部。 [0445] It should be noted that not all of the many configurations described herein force element can be adjusted to the lens placed inside the deformable member or element. 当所述透镜元件包括光学流体元件,这样的布置可以要求、或被促使非导电光学流体的使用,例如矿物质和硅油,另外,当关于与图117相关讨论的双作用配置,内部和外部力元件的组合可以被使用,其可以被这样配置以便互相独立地作用、互相同时作用、或选择性地以其他模式。 When the fluid lens element comprises an optical element, such an arrangement may be required, or cause an optical non-conductive fluid, such as mineral and silicone oil. In addition, when the dual role of the discussion related to the configuration of FIG. 117, internal and external forces combination of elements can be used, it may be so configured to act independently of each other, each act simultaneously, or selectively in other modes.

[0446] 均勻元件的适应可以促使所述可变形构件对力的的回应更均勻或对称,当多个分散元件的使用可以产生所述可变形构件的更不对称变形,部分依赖于所述可变形构件的柔性和硬度。 Adaptation [0446] uniformly element may cause the deformable member in response to force more uniform or symmetrical, when a plurality of discrete elements of the deformable member may produce a more asymmetrical modification, may depend in part on the flexibility and hardness of the deformable member. 相对硬的可变形构件将比相对柔性的可变形构件易于传输被应用在广泛地并且均勻地相对于邻近区域的所述元件的一个点的力。 The deformable member may be relatively stiff flexible than the relatively easily deformable transmission member it is applied widely and uniformly force the point of a member with respect to the adjacent area. 例如,当在整个可变形薄膜上所述目标是均勻的和对称的响应,产生所述可变形薄膜的相对柔性可变形材料的使用将易于支持均勻力元件的使用,例如具有环或垫圈配置的元件能够均勻地应用力环绕着所述可变形元件的圆周或外周,反之,产生所述可变形薄膜的相对硬性可变形材料的使用将易于支持两个力元件的使用,即使在组合应用中,将施加力在所述可变形薄膜不连续的区域上。 For example, when the deformable membrane over the whole of the target is uniform and symmetric response, generating the use of a relatively flexible deformable material deformable membrane will tend to support the use of a uniform force element, for example, a ring or gasket arranged force application member can be uniformly circumferentially surrounding the outer periphery or the deformable element, on the contrary, the deformable thin film is generated relatively rigid deformable material will tend to force the use of two support elements, even if the application in combination, applying a force on the deformable membrane to discrete areas.

[0447] 这里附加地讨论所述驱动装置聚合体,其他结构或设备可以被使用作力元件。 [0447] discussed additionally herein means the drive aggregate, other structures or devices may be used as a force element. 压电元件可以被使用来产生用来传输的移动力,是否水性地通过流体、气性地通过气体、机械地通过一个或多个力传输元件例如推力环。 The piezoelectric element may be used to generate a moving force for transmission, whether by an aqueous fluid, the gas through the gas, through one or more mechanical force transmission elements such as the thrust ring. 声音线圈结构可以被使用来产生和变化磁场, 为了使所述可变形构件变形,其将所述透镜元件的磁性元件。 The voice coil structure may be used to generate a varying magnetic field and, in order to make the deformable member is deformed, the lens element which the magnetic element. 图121表示具有流体元件5501在容器5502,其依次在外壳5503内。 121 shows a fluid in the container 5502 element 5501, which in turn within the housing 5503. 外壳5503被声音线圈5504环绕,其作用在磁性压力元件5505上使可变形薄膜5506变形。 5503 housing 5504 is surrounded by the voice coil, so that the effect of the deformable membrane 5506 deformed in the magnetic pressure element 5505.

[0448] 在图121的实施例中,所述压力元件是磁性的,并且声音线圈可以被定位以便当所述线圈被激活,所述压力元件使所述可变形构件变形,因为它被推向或拉离由所述声音线圈产生的磁场。 [0448] In the embodiment of Figure 121, the pressure element is magnetic, and the voice coil may be positioned such that when the coil is activated, the pressure member the deformable member can be deformed as it is pushed or pull away from the magnetic field generated by the voice coil. 透镜元件结合声音线圈具有很多配置参数,例如 Binding the lens element having a lot of configuration parameters voice coil, e.g.

[0452] d,所述声音线圈可以定位在所述可变形构件的上面、平行、或下面,包括在所述光学流体元件下面; [0452] d, the voice coil may be positioned on top of the deformable member, parallel, or below, comprising the following elements in the optical fluid;

[0467] 如上面注意到的,可能具有其中所述目标用来校正或减小确定类型的误差的情况,并且在这点上,改变所述可变形构件在整个变形区域上的厚度和/或微布局是可以的, 不同于被本发明激活的,当保持该可变性时产生具有球形分布的结构。 [0467] As noted above, may have a case where the target types determined for correcting or reducing the error, and in this point, changing the thickness of the deformable member is deformed over the entire area and / or micro layout is possible, unlike the present invention is activated, to produce a structure having a spherical distribution when holding the variability. 考虑到在使用中所述可变形构件被期望承受的变形的方向和程度,表面结构的这种变化可以被实现。 Taking into account the direction and degree of deformation is expected to be subjected in use the deformable member, this change of the surface structure can be implemented. 并且也可以被用来校正所述可变形构件的非均勻变薄,其可以在使用中发生。 And it may also be used to correct the non-uniformity of the thin deformable member, which may occur in use. 例如,假设所述可变形构件的边缘部分或区域是固定的并且只有内部区域承受变形,当所述可变形构件被从相对平坦或水平配置变形到凸起或凹陷配置时,可以是内部区域的中心部分将经历更薄比相邻区域。 For example, assume that an edge portion or region of the deformable member is fixed and only the inner region subjected to deformation, when the deformable member is disposed horizontally from a relatively flat or deformed to the convex or concave configuration, which may be internal region the central part of the experience is thinner than adjacent areas. 使用这种现象是可以期望的,但是可以替代地期望使它最小化或消失。 Using this phenomenon is desirable, but it may instead be desirable to minimize or disappear. 这可以被实现,通过简单地制造所述可变形构件的轮廓从在边缘相对较薄改为在中心相对较薄,以便这两个区域当变形时厚度相等,或者,设计或影响所述可变形构件的微结构以便当它从平坦到凸起或凹陷时所述可变形构件的的光学特性适当地保持常数是可能的。 This can be achieved simply by the contour of the deformable member manufactured from relatively thin at the edges to the center in the relatively thin, so that the two deformation regions when the thickness is equal to, or affect the design or deformable the optical properties of microstructures member so that when it is raised or recessed from the planar to the deformable member is suitably maintained constant is possible.

[0468] 所述可变形固体透镜元件、和由流体和可变形构件组合的所述透镜元件当用在所述透镜的两侧或表面时都可以是可变形的,如图127和1¾所示。 [0468] The deformable solid lens element, the lens element, and a combination of fluid and the deformable member when used in a surface of the lens or both may be deformable, and 127 as shown in FIG 1¾ . 关于图127的可变形固体透镜元件,可变形固体5601的“下”表面5602b可以由具有中心特征区域5604(显示为点线部分)的刚性边界元件5603(仅显示截面图)支撑,允许下表面5602b在响应来自于所述力元件的力时而改变形状。 The deformable solid lens element with respect to Figure 127, the surface 5602b "lower" deformable solid 5601 can be a region 5604 having a central characteristics (shown as a dotted line portion) of rigid boundary elements 5603 (only cross-sectional view) is supported, allowing a lower surface 5602b sometimes change shape in response to the force from the force element. 例如,下表面5602b,其显示为凸起的,在响应被所述力元件施加在与上表面560¾外周接触的压力元件(未示出)上的力时可以变得更凸起,并且其向下和/或向内压在所述可变形固体上。 For example, the lower surface 5602b, which is shown as convex, in response to the force being applied to the device (not shown) in the pressure member in contact with the outer circumferential surface of the upper 560¾ force may become more prominent, and that the lower and / or inwardly against said deformable solid. 依赖于下表面5602b有多可变形或弹性,该部件的大小和/或形状可以是这样,在没有任何力从所述力元件输入时下表面是充分平坦的, 下表面5602b也可以被附加的力元件独立控制,通过独立的力元件能够独立地和/或组合地作用在上和下表面上。 How surface 5602b elastically deformable or size of the component and / or the shape may be so dependent on the, in the absence of any force from the force input member is substantially planar surface nowadays, the lower surface 5602b may be additional forces member independently controlled by separate force element can be independently and / or in combination, act on the upper and lower surfaces. 可选地,刚性边界元件5603可以是固体的、有就是说,没有中心特征,并且从而将保持下表面5602b在预定的配置,其可以是平坦、凸起、或凹陷的,并且其将在响应所述力元件提供的力时不改变。 Alternatively, the rigid boundary element 5603 may be solid, that is to say there is not a central feature, and thereby maintaining a predetermined configuration on a lower surface 5602b, which may be flat, convex, or concave, and which will respond It does not change the force provided by the force member.

[0469] 所述可变形固体透镜元件、和由流体和可变形构件组合的所述透镜元件都可以是可变形的,当用在所述透镜的两侧或表面,如图127和1¾所示。 [0469] The deformable solid lens element, and by the fluid lens element and the deformable member may be a combination of both may be deformed when used in the sides or surfaces of the lens, and 1¾ 127 shown in FIG. . 关于图127的可变形固体透镜元件,可变形固体5601的“下”表面5602b可以由具有中心特征区域5604(显示为点线部分)的刚性边界元件5603(仅显示截面图)支撑,允许下表面5602b在响应来自于所述力元件的力时而改变形状。 The deformable solid lens element with respect to Figure 127, the surface 5602b "lower" deformable solid 5601 can be a region 5604 having a central characteristics (shown as a dotted line portion) of rigid boundary elements 5603 (only cross-sectional view) is supported, allowing a lower surface 5602b sometimes change shape in response to the force from the force element. 例如,下表面5602b,其显示为凸起的,在响应被所述力元件施加在与上表面560¾外周接触的压力元件(未示出)上的力时可以变得更凸起,并且其向下和/或向内压在所述可变形固体上。 For example, the lower surface 5602b, which is shown as convex, in response to the force being applied to the device (not shown) in the pressure member in contact with the outer circumferential surface of the upper 560¾ force may become more prominent, and that the lower and / or inwardly against said deformable solid. 依赖于下表面5602b有多可变形或弹性,该部件的大小和/或形状可以是这样,在没有任何力从所述力元件输入时下表面是充分平坦的, 下表面5602b也可以被附加的力元件独立控制,通过独立的力元件能够独立地和/或组合地作用在上和下表面上。 How surface 5602b elastically deformable or size of the component and / or the shape may be so dependent on the, in the absence of any force from the force input member is substantially planar surface nowadays, the lower surface 5602b may be additional forces member independently controlled by separate force element can be independently and / or in combination, act on the upper and lower surfaces. 可选地,刚性边界元件5603可以是固体的、有就是说,没有中心特征,并且从而将保持下表面5602b在预定的配置,其可以是平坦、凸起、或凹陷的,并且其将在响应所述力元件提供的力时不改变。 Alternatively, the rigid boundary element 5603 may be solid, that is to say there is not a central feature, and thereby maintaining a predetermined configuration on a lower surface 5602b, which may be flat, convex, or concave, and which will respond It does not change the force provided by the force member.

[0470] 相似地,图1¾的变形透镜元件的下表面5602b可以是附加的可变形构件而不是刚性边界元件,并且可以与上表面560¾相似起作用,响应于力元件,其是相对于被使用来影响上表面560¾形状的所述力元件是同一个或附加的。 [0470] Similarly, the lower surface 5602b of the deformable lens element may be an additional 1¾ FIG deformable member instead of a rigid boundary elements, and may play a role similar to the upper surface of 560¾, in response to the force element, which is used with respect to the force element to affect the shape of the upper surface 560¾ is the same or additional. 与在前面段落讨论的所述可变形固体配置相似,下可变形表面5602b可以被刚性边界元件(未示出)限界或限制,其将下表面5602b保持在预定配置,其可以是平坦、凸起、或凹陷的,并且其将在响应所述力元件提供的力时不改变。 With the deformable solid was discussed in the preceding paragraph is similar to the configuration, the deformable surface can be rigid boundary element 5602b (not shown) bounded or limited, the lower surface 5602b is maintained at a predetermined configuration, which may be flat, convex , or recesses, and which does not change when the force to be provided in response to the force element.

[0471] 如进一步可选的,可以以任意透镜形状提供所述刚性边界元件,例如凸状、双凸状、平面-凸状、凹状、双凹状、平面-凹状、凹-凸透镜、或以半月板的形状。 [0471] As a further alternative, may be provided a rigid boundary element arbitrary lens shape, for example convex, bi-convex shape, the plane - a convex, concave, double concave, plane - concave, concave - convex, or meniscus shape of a plate. 因此参考图130,所述透镜元件可以包括外壳5650和可选边界元件56M。 Thus with reference to FIG 130, the lens element may optionally include a housing 5650 and a boundary element 56M. 可以以任意形状提供外壳5650或可选边界元件56M之一,包括上面所列的,在至少每个的相应于所述透镜元件光路的那个区域。 Alternatively the housing may be provided one boundary element 5650 or 56M, including those listed above, in at least a region corresponding to each of the lens element in the optical path of an arbitrary shape.

[0472] 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。 [0472] The boundary member may be rigid, such as glass or plastic, or deformable, such as an elastomer. 当期望所述边界元件作为变形力被施加到所述聚焦元件上的结果而不承受任何变形时,如果所述边界元件的弹性是这样的,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,则条件是充分的。 When the desired modification as a boundary element force is applied to the result of the focusing element without receiving any modification, if the elastic member is such that the boundary, both when the focusing element is in the maximum deformation, the said boundary elements to be transmitted in response to the force or energy to it without deforming, the condition is sufficient. 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 boundary element comprises a focusing module, spacer element and the focusing element and the focusing element comprises a deformable membrane and a fluid, wherein the fluid is sandwiched between the film and the boundary element, use element by applying a pressure to the pressure of the fluid onto the focusing element is deformed, either by pressing the film in the direction of the boundary element, or by reducing the fluid in the boundary element and the thin film of between (e.g., by tightening the ring) 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 border element is not deformed, then when the pressure member to exert maximum pressure on the fluid, it should be sufficiently rigidly held 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的或变形的。 In other words, when the desired boundary element does not deform the module during focusing, requires only the boundary element in this case is not deformed, without the need for it or not completely rigid or deformable. [0473] 如所述的,可以使用玻璃作为所述边界元件,并且多种光学玻璃材料是商业上可获得的,包括,例如,可从美国纽约Corning的Corning DisplayTechnologies获得的Corning® EAGLE2000 Display Grade玻璃,和可以从美国宾夕法尼亚州Duryea Wkhott North America有限公司获得的N-BK 7玻璃。 [0473] As described, a glass member as the boundary, and the various optical glass materials are commercially available, including, for example, available from Corning in Corning DisplayTechnologies New York glass Corning® EAGLE2000 Display Grade , Ltd. and may be obtained from the Pennsylvania Duryea Wkhott North America N-BK 7 glass. 所述边界元件可以是厚度合适的,包括从大约0.
