Abstract

A bionic artificial compound eye manufactured on a concave mold with precision engraving method for imaging, which allows for the rapid fabrication of large-scale compound eyes at a low cost. Thousands of concave structures are accurately machined and positioned omnidirectionally in concentric rings with a minimum diameter of 100 μm on a hemisphere. The PDMS ommatidia can be obtained once replicated, which can greatly improve preparation efficiency, and the peel-off process can also be optimized by alcohol ultrasonic without edge damage. The optical performance and field of view of the artificial compound eye are also investigated, and the experimental results are around 120°. Furthermore, the combination of the prepared compound eye and the commercial CMOS camera successfully captures images of different shapes.

摘要

一种在凹模上采用精密雕刻成像方法制造的仿生人工复眼，可以低成本快速制造大尺寸复眼。数以千计的凹面结构在半球上以最小直径为 100 μm 的同心环被精确加工和全向定位。PDMS ommatidia 一次复制即可获得，可以大大提高制备效率，而且还可以通过酒精超声优化剥离过程，不会损坏边缘。还研究了人工复眼的光学性能和视场，实验结果在120​​°左右。此外，制备的复眼和商用 CMOS 相机的组合成功地捕获了不同形状的图像。
