可见与红外双波段折反光学系统设计

Optical design of visible and IR spectral catadioptric system

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640480非制冷焦平面探测器，设计了焦距185 mm、 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4.8 mm 3.6 mm；像素数759596），设计了焦距86 mm、F数达到4.5、视场为4的可见（电视）光学系统。

Abstract: Based on the requirements of miniaturization and light weight for airborne optic systems, IR and TV system were designed with the common light path. For the 640480 uncooled 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.
