摘　　要：为了满足EMCCD侦察探测装置的实际使用要求,设计了一个三视场光学系统。系统采用EMCCD接收,像元尺寸为16μm×16μm。通过对比4种成像系统结构形式的优缺点,选定三视场光学系统的初始结构形式,运用CODEV软件对其进行优化,实现600nm^850nm波段范围内三视场光学系统成像。设计结果表明,三视场光学系统的传递函数MTF在35lp/mm频率处均大于0.5,点列斑直径均小于像元尺寸,畸变均小于0.2%,成像对比度满足使用要求。In order to meet the practical requirement of EMCCD investigation and detection device, a three-field-of-view （FOV） optical system was designed. The electron multiplying charged coupled device （EMCCD） was used for receiving, and the size of the image pixel was 16 μm× 16 μm. By comparing the advantages and disadvantages of 4 different imaging structures, the initial structure of three-FOV optical system was chosen. Furthermore, the system was optimized by using CODEV software to guarantee the excellent image quality of the three- FOV optical system in the wavebands from 600 nm to 850 nm. The design results show that the MTF of three-FOV optical system is larger than 0.5 at 35 lp/mm, the size of the root- mean-square（RMS） spot is less than the size of the pixel, the distortion is less than 0.2%, and the image contrast satisfies the use requirement well.
