我们报道了一种用聚氯乙烯(PVC)/邻苯二甲酸二丁酯（DBP）凝胶制备透镜状微透镜阵列（LMA）的新方法。将PVD/DBP凝胶涂覆在玻璃基板上形成膜。在静电斥力的作用下，在直流电压的作用下，膜的表面可以产生正弦波。具有波浪形表面的膜起LMA的作用。通过切换阳极和阴极，阵列中每个透镜微透镜的凸形状可以转换为凹形状。因此，LMA可以呈现较大的动态范围。响应时间相对较快，驱动电压较低。LMA具有结构紧凑、光学各向同性和良好的机械稳定性等优点，在成像、信息处理、生物识别和显示等领域具有潜在的应用前景。
We report a new approach to preparing a lenticular microlens array (LMA) using polyvinyl chloride (PVC)/dibutyl phthalate (DBP) gels. The PVD/DBP gels coated on a glass substrate form a membrane. With the aid of electrostatic repulsive force, the surface of the membrane can be reconfigured with sinusoidal waves by a DC voltage. The membrane with wavy surface functions as a LMA. By switching over the anode and cathode, the convex shape of each lenticular microlens in the array can be converted to the concave shape. Therefore, the LMA can present a large dynamic range. The response time is relatively fast and the driving voltage is low. With the advantages of compact structure, optical isotropy, and good mechanical stability, our LMA has potential applications in imaging, information processing, biometrics, and displays.
