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640×480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759×596), 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 640×480 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.
