摘　　要：针对机载小型化、轻量化的环境要求,将红外和电视传感器进行共次镜形式的共光路设计。对于640×480非制冷焦平面探测器,设计了焦距185mm、F数达到1.3、视场为5.8°的长波红外光学系统。对于1/3″CCD(像面尺寸4.8mm×3.6mm;像素数759×596),设计了焦距86mm、F数达到4.5、视场为4°的可见(电视)光学系统。Based on the requirements of miniaturization and light weight for airborne optic sys‐tems ,IR and TV system were designed with the common light path .For the 640 × 480 un‐cooled focal plane array ,an infrared long wave system was presented with a focal length of 185mm ,field of view (FOV )of 5 .8° , F number of 1 .3 .For the 1/3" charge coupled device (CCD)(4 .8 mm × 3 .6 mm ,759 × 596pixels) ,a visible(TV) system ,which had 86mm focal length ,4° FOV and 4 .5 F number ,was completed .
