摘　　要：光电设备或光学瞄准设备的光学窗口对入射激光具有较强的反射特性,该特性被称为"猫眼"效应。"猫眼"效应具有2个特点:1)能使反射光线沿入射光的方向返回;2)可以获得高质量的反射光。因此,"猫眼"效应能够很好的解决激光侦听中高质量信号光的获取问题。本文从理论上分析了"猫眼"效应的产生机理,论述了基于"猫眼"效应的激光侦听技术原理,并对"猫眼"效应应用中的一些问题做了讨论。The realization of active laser ce is based the fact that the optical windows of electro-optical equipment have a strong reflect character towards incident laser beam, which is called ＂cat-eye＂ effect. The ＂cat-eye＂ effect has two characteristics. One is that it can make the reflected light go back alone with the initial light. The other is that it can obtain a high quality reflected light. Therefore, ＂cat-eye＂ effect can solve the problem that it can obtain high quality signal light of laser detective. In this paper, we have analyzed the theory of ＂cat-eye＂ effect production mechanism, discussed the effect of the laser based on the ＂cat-eye＂ effect protected reliably agait tective technology principle, and some problems of the cat-eye effect in application are discussed.
