基于探测光学表面反射光侦察远方观瞄器材

阐述了用激光扫描法侦察远方光学仪器的原理及实验技术。以红外光学系统和红外望远物镜为例,运用矩阵光学追迹法对三种探测方法进行了对比研究:①"猫眼效应";②"近似猫眼效应";③"剩余反射效应"。研究结果表明:在野外环境,"猫眼效应"产生的回波概率极低。在适当条件下,"近似猫眼效应"和"剩余反射效应"的应用效果优于严格"猫眼效应",是具备实用价值的侦察手段。

Distant optical equipment detection by detecting the reflection of optical surface

The principle and experiment technique of detecting the hostile optical devices based on reflection are described in this paper.Three kinds of detecting method are researched contrastively by the method of ray tracing:①the "Cat′s eye" effect;②the similar "Cat′s eye" effect;③the "surplus reflection" effect.Research results show that the probability of "cat′s eye" reflection is very low in the field environment.But in the right conditions,the probability of the similar "Cat′s eye" effect and the "surplus reflection" effect reflection is much bigger,which is of practical value for the combat field reconnaissance.
