摘　　要：变形光学系统具有双平面对称性,其在两个对称面内的焦距不同。利用变形光学系统能够在使用常规尺寸传感器的情况下获得更宽的视场。本文根据变形光学系统的一阶像差特性,提出了一种设计折反式变形光学系统的方法。使用双锥面(Biconic Surface)面型设计了一个折反式变形光学系统。系统在X OZ面内的焦距为500 mm,在Y OZ对称面内的焦距为1000 mm。系统F-number为10,全视场角为1°×1°。系统在80 lp/mm处的全视场调制传递函数均值高于0.3。系统整体结构紧凑,成像质量良好。The anamorphic optical system has a two-plane symmetry,with different focal lengths in the two symmetry planes.This system can obtain a wider field of view when using sensors with conventional size.We propose a method for designing catadioptric anamorphic optical systems based on their first-order aberration characteristics.A catadioptric anamorphic optical system is designed by using a biconic surface,with a focal length of 500 mm in the XOZ plane and 1000 mm in the YOZ plane.The system’s F-number is 10,and the full field angle is 1°×1°.The mean value of the full field of view MTF of the system is higher than 0.3 at 80 lp/mm.The overall structure of the system is compact,and the imaging quality is excellent.
