液体微透镜对自适应光学很有吸引力，因为它们提供了高速驱动和并行化成大型阵列的潜力。然而，在传统设计中，液体的共振以及驱动机构和/或设备架构的复杂性阻碍了这两个方面的成功集成。在这里，我们提出了一个多达100个微透镜的阵列，利用电润湿技术在超过1 kHz的频率上同步调制焦距。我们的新概念将每个微透镜边缘的钉扎接触线与电润湿控制的压力调节相结合，从而并行地驱动所有微透镜。这种设计使各种形状的微透镜得以发展。该设计在快速并行光开关、人工复眼和三维成像等方面具有潜在的应用价值。由刺激反应水凝胶激活的自适应液体微透镜，《自然》442,551-554(2006)，使用钉扎接触式振荡液体透镜的快速聚焦，NAT。光子学2,610-613(2008)。5.T.Krupenkin和J.A.Taylor，《反向电润湿作为一种新的高功率能量收集方法》，NAT。使用电子控制按需形成和合并微滴的微流体平台，“生物微流体5,011101(2011年)。可变焦距的流体透镜”，应用1。适用于微型相机的可变焦距液体镜头，“应用电润湿微棱镜实现灵活的广角光束控制”，Opt。无电极配置的可调谐液体微透镜阵列及其通过干涉显微镜的精确表征，《电润湿驱动空气滴扩散的分析》，Phys。如何使粘性表面变得光滑：交流电压电润湿中的接触角滞后，应用基于积分摄影的三维图像实时拾取方法，应用。1.简介自适应液体透镜是一种快速发展的光流控器件，它将微米级的流体和光的控制结合在一起，使光学传感、操作、成像和显示有了新的应用[1-6]。近年来，为了满足移动电话、外科内窥镜、安全摄像头和DVD播放机等各种应用日益增长的需求，各种自适应透镜的概念已经开发出来[7]。继基于液晶的方法之后，各种构型的新型液晶透镜已经被提出，它们使用响应性水凝胶[3]、压电性[8]、声学[4]和电润湿(EW)[9-14]作为驱动机制。后者对于设计紧凑和坚固的设备特别有用，该设备结合了简单的电驱动和亚毫米镜头的超过视频率的驱动速度。A劣势…

Liquid microlenses are attractive for adaptive optics because they offer the potential for both high speed actuation and parallelization into large arrays. Yet, in conventional designs, resonances of the liquid and the complexity of driving mechanisms and/or the device architecture have hampered a successful integration of both aspects. Here we present an array of up to 100 microlenses with synchronous modulation of the focal length at frequencies beyond 1 kHz using electrowetting. Our novel concept combines pinned contact lines at the edge of each microlens with an electrowetting controlled regulation of the pressure that actuates all microlenses in parallel. This design enables the development of various shapes of microlenses. The design presented here has potential applications in rapid parallel optical switches, artificial compound eye and three dimensional imaging.

Introduction Adaptive liquid lenses belong to the rapidly growing class of optofluidic devices that combine the control of fluids and light on the micrometer scale to enable novel applications for optical sensing, manipulation, imaging and displaying [1-6]. Various concepts of adaptive lenses have been developed in recent years to match the increasing demand for a variety of applications including mobile phones, surgical endoscopes, security cameras and DVD players [7]. Next to liquid crystal-based approaches novel liquid lenses in various configurations have been proposed using responsive hydrogels [3], piezoelectricity [8], acoustics [4] and Electrowetting (EW) [9-14] as actuation mechanisms. The latter is particularly useful for the design of compact and robust devices combining simple electrical driving with actuation speeds exceeding video rate for sub-millimetric lenses. A disadvantage …
