Abstract

In order to solve the problems of traditional optical image de-rotation parts such as large volume, large gyration radius, and wide beam aperture, this paper analyzes the working principle of anamorphic rotation system by using the reflection matrix theory. Based on the concentric structure, the Offner-type reflective relay system with compact construction and image de-rotation is obtained. This structure has the advantages of real entrance/exit pupils, long exit pupil distance, and small image surface size, which is suitable for a new generation of airborne optoelectronic imagers.
