利用Zemax分析“猫眼效应”的激光反射特性

利用Zemax镜头设计软件建立了共轴的简化"猫眼效应"反射模型,并结合其强大的物理光学传播分析功能,仿真分析了目标镜头的口径、焦距、焦平面反射元件尺寸、倾斜度等主要参数对"猫眼效应"激光反射特性的影响。仿真分析的结果表明,目标镜头的"猫眼效应"激光反射特性是受目标参数和入射激光特性所共同制约的,对于空中目标来说,其"猫眼效应"的激光反射特性完全可以为激光主动探测所用。

Laser reflected character of" cat eye effect "by the Zemax

We establish a predigested and coaxal reflected model of "cat eye effect" by the optical design software named Zemax.By using its powerful function of physical optics transmission and analysis,we analyze the laser reflected character of "cat eye effect" restricted by the main parameter of the target lens,including aperture,focus,size,gradient of apparatus on the focal plane,and so on.The result of emulation shows that the laser reflected character of "cat eye effect" of the target lens is restricted by the parameter of target and incident laser together.For the aerial target,the laser reflected character of its "cat eye effect" can be absolutely used for the active detection.
