详细讨论了三反射式光学系统的设计方法,从初级像差理论出发推导出了三反射式系统初始结构的计算公式,并且得出了系统结构形式与其基本结构参数和焦距之间的关系。通过设计实例讨论了不同的三反射式光学系统的特点及其应用。设计了大视场、小F数且实现衍射极限成像的Cook-TMA光学系统和有利于杂散光抑制、小F数且实现衍射极限成像的Rug -TMA光学系统。

The design of three-mirror system is discussed in detail and the formulation for calculating the initial structure of three-mirror system is derived based on the primary aberration theory, and the relationship between the system structure and its basic structure parameters, focal length is deduced. The characteristics and applications of different three-mirror systems were discussed based on design examples. Two typical three-mirror optical systems are designed. One is Cook-TMA optical system with a wide field of view, small F number, and the diffraction limit imaging, and the other is Rug-TMA optical system which is propitious to suppress the stray light with small F number and achieves the diffraction limit imaging.
