摘要
在卡塞格林光学系统的设计中引入曼金反射镜、中继镜组,以提高卡塞格林光学系统承担视场和相对孔径的能力。通过设计实例表明,这种改进后的卡塞格林系统承担视场、相对孔径的能力得以很大提高,像质、结构长度满足设计的要求。
To ameliorate the field of view and relative aperture of Cassegrain Optical Systems, Mangin Mirror and relay lens are introduced into the design of Cassegrain Optical System. The design example shows abilities of the ameliorated Cassegrain Optical System bearing field of view and relative aperture are improved greatly. Final image quality and structure accord with the design requirements.
