红外光学系统无热化热膨胀凸轮 Infrared optical system Athermalization Thermal expansion Cam

摘要

为了介绍简单机械结构实现红外光学系统无热化的原理和方法,首先简单比较了国内外进行红外光学系统无热化设计的三种方法,然后给出了在红外3～5μm波段、3°视场范围和-40～60℃工作温度范围下经过无热化设计后的系统设计结果.结果表明,使用简单机械结构,不仅能在较大视场和较宽的工作温度范围内获得接近衍射极限的成像质量,而且系统结构简单,工作可靠.

Abstract

In order to describe principle and method of the athermalizing technique using simple me- chanical framework in this thesis, firstly, three ways of athermalizing of infrared optical system are com- pared.Secondly, an optical system working at 3～5 μm, 3°field of view and - 40～60 ℃ temperature range was designed. Furthermore, the image quality approaching the diffraction limit in a larger spatial field view and wider thermal range can be obtained when simple mechanical framework is used in the optical system.
