为了实现大视场，我们提出了由多个可调焦微透镜组成的微透镜阵列。设计了连接相邻微透镜的柔性聚合物桥，以减少微透镜阵列的包裹应力和变形。每个微透镜，通过水-油界面形成，由一个热响应的水凝胶执行器单独调节。该阵列中每个微透镜的焦距范围从毫米到无穷大不等。本文还演示了一种基于球面微透镜阵列的光学成像系统原型，该系统包括一个电荷耦合器件、一个光纤束和一个三维旋转平台。(2010 - 0273)
We present microlens arrays consisting of multiple focus-tunable microlenses omnidirectionally fabricated on spherical surfaces, to realize large field of view. Thin flexible polymer bridges connecting adjacent microlenses are designed to reduce the wrapping stress and deformation of the microlens array. Each microlens, formed via water-oil interface, is individually tuned by a thermo-responsive hydrogel actuator. The range of the focal length of each microlens in this array varied from millimeters to infinity. A prototype of optical imaging system based on such a microlens array on a spherical surface, including a charged-coupled device camera, a fiber bundle, and a 3-D rotational stage, is demonstrated as well.
