摘要

为了实现体积小、视场大、对运动物体敏感的成像装置，基于昆虫复眼建立了一种利用光纤面板作为折转光学元件的多孔径大视角成像实验系统，对该系统采用的成像单元、子眼分布角度及折转元件性能进行了分析，有效提高了离轴光线利用率，改善了复眼成像系统边缘成像质量差。根据系统整体视场角度要求，采用9眼成像通道并计算各成像通道的分布位置及角度，然后对单个子眼通道进行优化设计，保证系统视场角度及成像质量，最后分析成像透镜、折转元件和光探测阵列的匹配问题，选择最佳的折转方案。实验表明，利用光纤面板作为折转元件的多通道成像实验系统实现大视角成像功能，视场角度可达120°，相比传统的单孔径成像系统可以实现小体积下的大视角成像功能。

Abstract

In order to realize artificial compound eyes with small volume

large field of view and sensitive to moving objects

a multi-aperture and large angle imaging experiment system was established

which used a fiber optic panel as deflector optical elements. The imaging unit of this system

the distribution angle of the ommatidia and the performance of the deflector element were analyzed and studied

effectively improving the utilization rate of off-axis light and image quality of the compound eye imaging system. First

according to the whole field angle requirement of the system

nine ommatidia channels were used to calculate the distribution and angle of each imaging channel. Then

the design of single ommatidia channel was optimized to ensure the system field angle and imaging quality. Finally

matching problems in imaging lens

deflector elements and light detection array were analyzed

thus selecting the best deflector program. Experiments show that the multi-channel imaging experiment system with fiber optic panel as the folding element can realize the large-angle imaging function

and the viewing angle can reach 120°. Compared with the traditional single-aperture imaging system

the system can realize the large angle imaging function under a small volume.
