手持双视场红外光学系统设计
Design of Hand-Held Dual Field-of -View Infrared Optical System
摘要
介绍了一种采用中波640×512元红外焦平面探测器的红外双视场光学系统设计实例，该系统工作波段为3.7～4.8 μm，变倍比为3倍，F数为4，采用切换变倍方式实现变倍。该系统具有体积小，重量轻，分辨率高，像质高，工作温度范围宽等优点，能够很好地满足手持热像仪的实际需要。
Abstract
A rotate-zoom infrared optical system for medium wave 640×512 IR FPA (Focal Plane Arrays) thermal imager is designed in this paper. The operating waveband of the system is 3.7～4.8 μm, zoom ratio is 3×, and F-number is 4. The design result showed the system has compact structure, light weight, high resolution, excellent image quality, and reliable performance within required temperature range, thus meeting the requirements of the hand held thermal imager design.
