摘　　要：基于三反射镜的三级相差理论,通过自定义优化函数,并使用遗传算法寻找合适的三反射镜光学系统的初始结构参数,利用光学设计软件ZEMAX对初始结构进一步离轴优化,设计出了视场角为18°×0.6°,焦距为1700 mm,入瞳直径为200 m的像方远心离轴三反射镜光学系统。该光学系统无中心遮拦,成像质量接近衍射极限,适用于空间遥感领域。Based on the third order aberration theory, a merit function is established, genetic algorithm is employed to find the initial structure parameters with minimum merit function then the initial structure is loaded to ZEMAX for further optimization. A telecentric three-mirror reflective system with effective focal length of 1700 mm, entrance pupil diameter of 200 mm and field of view of 18°×0.6° is designed by making the y- field off axis. The performance of the system is close to the diffraction limit and it is unobstructed and suit for the field of space optical remote.
