摘要
本文讨论了反射系统、折反射系统的设计问题。得出焦距4000毫米,相对孔径1:4,视场3°,调制传递函数0.40,80％能量集中的弥散盘半径6.5微米的结果。
In this paper, catoptric and catadioptric systems are discussed. As an example, a Schmidt system with specifiation: focal length 4 meters, relative aperture f/4, angular field of view 3° is designed, when spatial frequency is 150 linepairs per mm, the MTF is about 0.4.
