技术领域 Technical Field

[0001] 本发明属于微光学技术领域,涉及一种使用离子液体作为导电液体的液体电润湿变焦透镜,具体涉及一种可用于低温、高温、真空等较苛刻条件下,能够适应外界环境温度剧烈变化,既可用于普通成像系统又能用于近红外成像的液体变焦透镜。 [0001] The present invention belongs to the technical field of micro-optics, relates to the use of an ionic liquid as a liquid electrically conductive fluid wetting the zoom lens, in particular to a relatively harsh conditions may be used under low temperature, high temperature, vacuum, etc., to adapt to the ambient temperature dramatic changes, both for general imaging system can be used near-infrared imaging of liquid zoom lens.

背景技术 Background

[0002] 变焦透镜在光学系统中具有十分重要的作用。 [0002] The zoom lens has a very important role in the optical system. 近年来随着光通信技术的发展以及对便携式摄像装置需求的不断增大,微型变焦透镜的需求随之增大。 In recent years, with the increasing development of optical communication technology and the demand for portable imaging device, the demand for micro zoom lens increases. 目前市场上的微型镜头主要是小型的传统机械运动透镜,其采用玻璃或者塑料通过注塑的方法得到小镜头,然后通过光学几何设计,将小型的镜头集成在位置可调的微型镜筒内,通过改变镜头的位置完成改变镜头焦距的目的。 Currently the micro lenses on the market are mainly small, traditional mechanical movement of the lens, which is made of glass or plastic lenses obtained by injection of a small method, and then through the optical geometric design, the compact camera is integrated in the position of an adjustable micro tube, through change the position of the lens focal length of the lens aim to complete the change. 由于需要对透镜光学系统不断进行优化设计,传统机械运动透镜组结构复杂、能耗高、易磨损、造价昂贵,尺寸濒临极限,已不能满足产业发展的需求。 Due to the need to continue to optimize the lens optical system design, a traditional mechanical movement of the lens group structure complex, high energy consumption, easy to wear, high cost, size verge limit, can not meet the needs of industrial development. 为实现变焦透镜的微型化并提高其使用寿命,目前国际上已经提出了一些新型变焦微透镜技术,液体透镜就是其中的一种,相较于其他新型微透镜而言,液体透镜的结构最为简单,且成像质量较好。 To achieve miniaturization of the zoom lens and increase its service life, now the international community has made a number of new micro zoom lens technology, the liquid lens is one of them, compared to other new micro-lens, the structure of the liquid lens of the most simple , and the image quality is better.

[0003] 通过外加电压改变部分导电液体接触角的现象称为电润湿效应(electrowetting),电润湿效应可用于控制微小液滴的表面曲率。 [0003] The change of the conductive fluid contact angle of the phenomenon known as electrowetting effect (electrowetting) by the applied voltage, the electrowetting effect can be used to control the tiny droplets of surface curvature. 基于电润湿的液体变焦透镜利用电压改变液体的表面张力,从而改变液滴的表面曲率,实现液体透镜的变焦。 Based on electrowetting zoom lens by the voltage change of liquid surface tension of the liquid, thereby changing the surface curvature of the droplet, the liquid to achieve a zoom lens. 与传统的机械运动透镜组相比,基于电润湿的变焦液体透镜的优势在于结构简单、体积小、重量轻、电功耗低、成本低、磨损小、轻便易携带。 Compared with the traditional mechanical movement of the lens group, based on the advantages of electrowetting liquid zoom lens is a simple structure, small size, light weight, low power consumption, low cost, low wear, light and easy to carry. 基于以上优点,液体透镜已经开始工业化规模生产,并广泛地应用于光学装置、显示装置和微机电系统中。 Based on the above advantages, the liquid lens has started industrial-scale production, and is widely used in optical devices, display devices and micro-electromechanical systems.

[0004] 目前国际上多家公司公开了焦距可调的液体透镜的设计和相关专利(US6014259, US6538823, US6545815, US6625351, US6665127, US6768539, US6778328, US6893877, EP1963894A2, EP1804090A1, EP1870741A1, EP1870742, EP1884805, CN200580011389. 9, CN02141675. 3, CN200710086069. 0)。 [0004] The current international companies disclosed an adjustable focal length of the liquid lens design and related patents (US6014259, US6538823, US6545815, US6625351, US6665127, US6768539, US6778328, US6893877, EP1963894A2, EP1804090A1, EP1870741A1, EP1870742, EP1884805, CN200580011389 . 9, CN02141675. 3, CN200710086069. 0). 其中,ASTART公司采用压电材料的膜片改变液体膜的曲率方向和半径,从而达到使液体透镜变焦的目的。 Wherein, ASTART company uses a piezoelectric material diaphragm changes direction and radius of curvature of the liquid film, so as to achieve the purpose of the liquid zoom lens. LUCENT公司提出了改变电极的设计、 电极的表面特性、电极间表面特性等方法来调节液体透镜的焦距,并于2003年推出世界上第一款纯电力控制的液体变焦透镜,在电场作用下能改变自己的光学特性。 LUCENT company makes a change to the design of the electrodes, the surface characteristics of the electrode, the electrode between the surface characteristics and other methods to adjust the focus of the liquid lens, and launched the world's first liquid zoom lens pure power control in 2003, in the electric field energy change their optical properties. . 2004年,荷兰PHILIPS公司展出了利用Fluid Focus技术开发出的新型无机械活动部件的变焦液体透镜。 In 2004, the Netherlands PHILIPS company exhibited liquid zoom lens use Fluid Focus technology to develop a new type of no mechanical moving parts. 2006年法国VARI0PTIC公司推出了两款液体透镜Arctic320及Arctic416,实现了商品化的液体透镜,可应用于手机、医疗以及数字摄影市场。 2006 French VARI0PTIC company introduced two liquid lens Arctic320 and Arctic416, commercialized liquid lens can be used in mobile phones, medical, and digital photography markets.

[0005] 基于电润湿的变焦液体透镜的液体由导电液体和填充液体两种液体组成。 [0005] The liquid electrowetting zoom lens based liquid made of a conductive liquid and liquid-filled two liquid components. 为实现较好的变焦功能,要求这两种液体必须具有相匹配的密度和较大的折射率差以及较小的粘度和合适的表面张力。 To achieve a better zoom function requires two liquids must match the density and refractive index difference between the larger and smaller viscosity and surface tension suitable. 另外,为满足液体透镜商业化的要求,必须保证这两种液体在较高温度下,如80C长期运行不变质、不混合、不挥发。 Further, in order to meet the requirements of commercial liquid lens, must guarantee both liquids at elevated temperatures, e.g. 80 C long-term operation is not bad, not mixed, non-volatile. 但是,一般传统的液体透镜使用无机盐的水溶液作为导电液体,在长时间的较高温温度下两种液体之间易产生物理变化和化学反应,无机盐的水溶液在较高温度时易挥发,使透镜可靠性不佳,而当外界环境温度高于80C时, 液体透镜无法工作。 However, in general an aqueous solution of an inorganic salt using a conventional liquid lens as a conductive liquid, under relatively high temperature for a long time a temperature between the two liquids is easy to produce the physical changes and chemical reaction, an aqueous solution of an inorganic salt volatile at higher temperatures, so that poor reliability of the lens, and when ambient temperature is above 80 C, the liquid lens is not working. 迄今为止也没有关于具有较好的高温可靠性的液体透镜的报道。 So far no reports of having good high temperature of the liquid lens reliability. 而当温度低于0C时,由于受到水自身物理化学性质的制约,使得使用无机盐的水溶液作为导电液体的液体透镜无法使用,即使可以通过向无机盐的水溶液中添加抗凝剂的方法降低其凝固点,但其极限值也只能达到-20C。 And when the temperature is below 0 C, due to the constraints of their own physical and chemical properties of water, making use of an aqueous solution of an inorganic salt conductive liquid as a liquid lens can not be used, even by adding to an aqueous solution of an inorganic salt method anticoagulant lowering its freezing point, but can only reach its limit -20 C. 目前,没有关于可用于低温(<_20C)情况下液体透镜的相关报道。 Currently, no reports on available for cryogenic liquid lens under (<_20 C) conditions. 并且,当环境温度剧烈变化时,由于无机盐的水溶液具有挥发性,容易在顶部端面产生微小液滴,降低成像质量,影响成像效果。 And, when the ambient temperature dramatic changes, due to volatile inorganic salt solution, easy to produce tiny droplets on the top end surface, reducing image quality, impact imaging results. 尽管大量的专利描述了基于电润湿的液体透镜的机械构造,但未公开液体透镜的液体组成物。 Despite the large number of patents describe the mechanical structure of the liquid lens based on electrowetting, but does not open the liquid composition of the liquid lens. 而且,在这些专利中也没有给出可以根本防止两种液体混合、挥发的可用于液体透镜的液体组成物。 Moreover, in these patents can be given no fundamentally prevent mixing of two liquids, volatile liquid composition may be used to the liquid lens. 众所周知,在红外成像技术中所使用的红外胶片能记录波长在0. 4〜1. 35 μ m间的可见光和近红外线,而具有红外摄影功能的数码相机的光电耦合器(CXD)能响应的波谱为0. 4〜1. 1 μ m。 As we all know, the infrared film in infrared imaging technology can be used in the recording wavelength between 0. 4~1. 35 μ m in the visible and near infrared, and infrared photography optocouplers enabled digital camera (CXD) can respond spectrum is 0. 4~1. 1 μ m. 因为水对0. 9〜 1. Ιμπι之间的近红外线有较强的吸收作用,所以使用无机盐的水溶液作为导电液体制作的液体透镜无法用于近红外成像。 Because the water of the near-infrared 0. 9~ 1. Ιμπι between the strong absorption, so using an aqueous solution of inorganic salts as conductive liquid produced liquid lens can not be used near-infrared imaging. 基于上述原因,使用无机盐的水溶液作为导电液体制作的液体透镜,其使用范围受到很大限制。 For these reasons, the use of an aqueous solution of an inorganic salt produced as a conductive liquid of the liquid lens, its use is very limited.

[0006] 离子液体(RTILs) —般是由特定的体积相对较大的结构不对称的有机阳离子和体积相对较小的无机阴离子构成的、在室温或近于室温下呈液态的熔盐体系。 [0006] The ionic liquid (RTILs) - like organic cations and relatively bulky volume by a specific asymmetric structure relatively small inorganic anions, and at or near liquid at room temperature molten salt system. 和传统的分子溶剂相比,往往展现出独特的物理化学性质和特有的功能,是一类值得研究发展的新型的绿色介质或软功能材料(soft materials)。 Compared with traditional solvent molecules, often exhibit unique physical and chemical properties and unique features, it is a kind of worthy research and development of new functional materials green medium or soft (soft materials). 80年代早期,英国BP公司和法国的IFP等研究机构开始较系统地探索RTILs作为溶剂与催化剂的可能性。 In the early 1980s, Britain's BP and France IFP and other research institutions began to systematically explore the possibility RTILs solvent and as a catalyst. 90年代以后,一系列性能稳定的RTILs的成功合成使其在催化与有机合成领域的应用研究逐渐活跃。 90 years later, a series of successful synthesis of stable performance makes it RTILs applied research in the field of catalysis and organic synthesis increasingly active. 离子液体具有液程宽(_50C -200C )、热稳定性好、具有良好导电性、物理化学性质(折光率、密度、粘度) 可调、蒸汽压低等一系列优点。 Ionic liquid has hydraulic drive wide (_50 C -200 C), good thermal stability, good electrical conductivity, physical and chemical properties (refractive index, density, viscosity) adjustable, vapor pressure and low number of advantages. 由于离子液体在-50C -200C的温度范围内均为液态,且蒸汽压低,几乎不挥发,因此相比于使用无机盐的水溶液作为导电液体制作的液体透镜而言, 离子液体变焦透镜可用于低温、高温、真空等极端条件下,并且可以适应外界环境温度剧烈变化。 Since ionic liquids are liquid at -50 C -200 C temperature range, low vapor pressure and hardly volatile, as compared to the use of an aqueous solution of an inorganic salt produced as a conductive liquid of the liquid lens, the zoom ionic liquids lens can be used under extreme conditions and low temperature, high temperature, vacuum, etc., and can adapt to drastic changes in ambient temperature. 因为离子液体具有可设计性,其物理化学性质(折光率、密度、粘度)可调,故可根据不同的需求设计、制作出具有不同折光率、密度、粘度的离子液体,从而组成多种具有不同焦距调节范围的离子液体透镜。 Because ionic liquids having a design, and its physical and chemical properties (refractive index, density, viscosity) adjustable, it can be designed according to different needs, to produce ionic liquids having different refractive index, density, viscosity, and thus form a variety has Different focal length lens adjustment range of ionic liquids. 此外,在没有外加电压作用的初始状态下,使用无机盐的水溶液作为导电液体制作的液体透镜为凹透镜,需要施加较大的电压使其由凹透镜变为凸透镜才能实现透镜的聚焦。 Furthermore, in the absence of applied voltage in the initial state, the use of an aqueous solution of an inorganic salt as a conductive liquid lens is a concave lens made of a liquid, it is necessary to apply a large voltage can be achieved by a concave convex lens into focus.

[0008] 本发明的基于离子液体的电润湿变焦透镜其初始状态即为凸透镜,因此与使用无机盐的水溶液作为导电液体制作的液体透镜相比,只需较低的电压即可实现聚焦。 [0008] The present invention is based on ionic liquids wetting power zoom lens is the lens to its initial state, and is therefore an aqueous solution of inorganic salts as conductive liquid produced by the liquid lens compared to a lower voltage can be realized only focus. 由于离子液体在0. 9〜1. 1 μ m的近红外区有较好的透过率,使得离子液体变焦透镜亦可应用于红外成像领域。 Since the ionic liquid has good transmittance in the near infrared region 0. 9~1. 1 μ m, such that ionic liquids can also be applied to a zoom lens infrared imaging. 综上所述,离子液体是一类可应用于变焦液体透镜的理想介质,且在国内外未见关于离子液体在电润湿液体变焦透镜中应用的报道。 In summary, ionic liquids is the ideal medium for a class can be applied to the liquid zoom lens, and no respect at home and abroad ionic liquids reported liquid electrowetting zoom lens applications.
