Abstract
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.
