摘要: 根据光电探测器的“猫眼效应”，针对成像光学系统的视轴，从理论上分析了利用激光对超视距系统进行视轴对准的可行性，特别分析了激光器输出功率参数、接收探测器焦平面是否离焦等关键参数。研究结果表明，基于“猫眼效应”的超视距系统进行视轴对准在理论上和实验设计上是可行的。

Abstract: In an optical system, “cat eye effect” can be modeled as a focus lens system. When a system has some opto-electrical devices and is illuminated by a laser beam, the laser beam will be reflected from the system along incident direction as a result of “cat eye effect”. The “cat eye effect” is the inherent feature of opto-electrical devices. In this paper, the pointing capability of line-of-sight (LOS) over the horizon target (OTHT) is analyzed, especially the parameters of laser power. The results show that it is feasible to point different targets over the horizon using “cat eye effect”.-
