提出了一种基于多焦点、长焦距微透镜阵列的仿生复眼，以提高图像质量。仿生复眼设计了七层微透镜阵列。这些微透镜阵列将焦点集中在同一点上，组成一个视觉系统。本研究分为两个部分。第一部分是计算各层微透镜阵列在同一表面上的聚焦情况，然后利用光学仿真软件ZEMAX对光路进行仿真。第二部分是仿生微透镜阵列复眼的制作。通过光刻制作的光刻胶柱阵列和随后的热回流可以形成微透镜阵列。溅射后，弹性PDMS用作塑料复制品。然后用3D打印机打印出凹曲面的PDMS模型作为半球形透镜模具，并将复制的微透镜阵列贴附在开口处。由于半球内产生负压，可以形成曲率复眼微透镜阵列。利用微透镜阵列可以制作出曲率仿生复眼。ZEMAX软件可用于模拟复眼的长焦距光路。
This paper presents a bionic compound eye using microlens array with multi-focus and long focal length for improving a selected imagery quality. There are seven layers of microlens array designed in the bionic compound eye. These microlens array will focus on the same point composed a visual system. There are two parts in this study. The first part is the calculation of each layer's microlens array focus on the same surfaces, Then the light path can be simulated by the optic simulation software, ZEMAX. The second part is the bionic microlens array compound eye fabrication. The photoresist column array fabricated by lithography and followed by the thermal reflow can form the microlens array. Elastic PDMS was used as a plastic replicate after sputtering. Then the 3D printer was used to print the PDMS model which was concave curved surface as a hemispherical lens mold and attached the replicated microlens array on the openings. The microlens array can be formed the curvature compound eye microlens array because of the negative pressure resulted in the hemisphere. A curvature with microlens array for the bionic compound eye can be fabricated. The ZEMAX software can be used to simulate the light path with a long focal length for the compound eye.
