摘要
本文研究了三反射镜光学系统的像差特性,提出用比较直观的解方程式的方法来设计三反射镜光学系统,举例说明了该系统的像差平衡及像质评价问题,得出焦距为4000mm,相对孔径为1:4,视场角为3°,弥散盘最大半径为6.35μm,对于空间频率150lP/mm,调制传递函数为0.36的结果。
In this paper the aberration properties of three-mirror optical system are Investigated. A more directly solving equation method is presented to design this system. The aberration balancing and image evaluation of this system are described. The results show that at the optical system with focal length of 4 meters, relative aperture of f/4, angular field of view 3°, the largest spot radius is 6.35 micrometers and the MTF is 0.36 at spatial frequency 150 linepairs per mm.
