To solve the problems existing in the Modulating retro-reflector optical system which can not simultaneously satisfy the wide field of view, reversibility of light path, small F number and all lens are spherical surface, an optical system with wide field of view and near the diffraction limit is designed. The structure of optical system is optimized and analyzed with an optical design software, 30 degree view field angle and F number of 1.3 CMERR optical system has been designed, all lens are spherical lens and near diffraction limit. The results show that within the whole field of view, the lens retro-reflects incidence beam perfectly, and can match the small size modulator. It ensures the contrast ration of the whole system which has advantages of low cost and easy processing.
