大视场曲面仿生复眼光学系统设计

为了解决传统成像系统存在的大视场与高分辨率不可兼得的问题，设计了大视场曲面仿生复眼光学系统。首先，针对所采用的间隔型圆周分层微透镜阵列排布方式，建立了一种曲面仿生复眼光学系统成像原理数学模型；再使用微透镜阵列与转像系统相结合的成像方案解决了微透镜阵列所成的曲面像与平面探测器不匹配的问题；并使用光学设计软件对该系统进行仿真分析及公差分析。设计得到的曲面仿生复眼光学系统总视场为152°，组合系统的焦距为61.14 mm，角分辨率为2.304″，系统总长为16.39 mm。相对传统的大视场成像系统而言，此曲面仿生复眼成像系统的畸变更小、分辨率更高。

Design of curved bionic compound eye optical system with large field of view

To solve the problem that the large field of view and high resolution of the traditional imaging system can not be achieved simultaneously, a large field of view curved bionic compound eye optical system was designed. Firstly, aiming at the arrangement of the spaced-type circumferential layered micro-lens array, a mathematical model of the imaging principle of the curved bionic compound eye optical system was established. The imaging scheme that combining the microlens array and the transferring image system was proposed to solve the matching problem of curved surface image which formed by the micro-lens array and the planar detector; and optical design software was used for simulation and tolerance analysis. The designed curved bionic compound eye optical system has a total field of view of 152°, a combined focal length of 61.14 mm, an angular resolution of 2.304″, and a total length of 16.39 mm. Compared with the traditional large field of view imaging system, the curved bionic compound eye imaging system has smaller distortion and higher resolution.
