基于Lighttools和Matlab的内辐射杂光分析方法研究

Research of stray light in the IR system based on Lighttools and Matlab

针对红外系统内辐射杂光对系统成像影响严重的问题,以一个具体红外系统为例,基于Lighttools和Matlab软件,提出一种适用于红外系统的内辐射杂光分析方法。针对分析结果所确定的需要重点消除杂光的表面,提出了相应的杂光消除措施。经验证,该方法对于寻找内辐射杂光来源,消除内辐射杂光具有很好的效果和适用性。

Aiming at the serious effect of the inner radiation stray light on system imaging,an analyzing method of in-ner radiation stray light for IR system based on Lighttools and Matlab is put forward.Though the analysis,the surfaces that introduce the stray light are determined,and stray light elimination measures are put forward.The results show that the method has good effect and applicability for the searching of the inner radiation stray light.
