含衍射透镜的卡塞格林红外光学系统设计

Design of Cassegrain Infrared Optical System with Diffraction Lens

该设计将衍射透镜引入到卡塞格林红外光学系统中。设计结果表明,衍射透镜的引入增大了卡塞格林光学系统的视场和相对孔径,改善了成像质量;同时也降低了加工工艺的要求,大大节约了成本。

Diffraction lens is used in Cassegrain infrared optical system. The design of view and relative aperture of the system are increased to improve imaging quality. And requirements are reduced to save the cost greatly. results show that the field the processing technology.
