摘要

摘要: 分析了双通道投影系统光路，介绍了准直投影光学系统的设计。此投影系统由目标源和干扰源2个通道组成，2个通道共用一个光学系统。光学系统采用二次成像结构来满足外形及质量的要求，在光学系统的最后一面和焦平面之间插入分束镜来引入目标源通道，并通过减小分束镜的厚度来控制干扰源通道的像差。光学系统工作波段为8 m～12m , 焦距315.69 mm，视场8.5，入瞳距900 mm，最后的像质表明此光学系统能够满足使用要求。

Abstract: This paper analyzes ray paths of the dual-channel projection system and introduces the design of the projection collimator optics. The projection system consists of a target source generator and an inference source generator sharing the same optics. The optics uses a re-imaging configuration to meet the packaging requirement. The beam splitter is located between the last surface and the focal plane of the optics to combine the target source channel. By reducing the thickness of the beam splitter, the aberration of the optics in the inference source channel is reduced. The optics collimates the output from an infrared source in the 8 m~12 m waveband and enables an imaging system with 8.5 field of view to be tested. The effective focal length of the optics is 315.69 mm and the entrance pupil relief is 900 mm.The obtained performance shows the optics meet the requirements of the projection system.
