摘　　要：　阐述了"猫眼效应"的基本原理,并在此基础上对"猫眼效应"进行了实验验证。实验结果表明,光电探测器的确存在"猫眼效应"。利用"猫眼效应"进行远距离的目标探测与识别能够简化系统并有效提高目标探测识别的概率,对今后选取合适的方案进行空间目标捕获、跟踪和瞄准有一定的参考意义。In an optical system, 'cat eye effect' can be modeled as a focus lens system. Based on the model and Fourier transform, when a system has some optoelectronic devices and illuminated by one laser beam, the laser beam will be reflected from the system along incident direction as a result of cat eye effect. The experimental proof is made by the detection of laser power back-scattered from the opto-sensitive material, such as CCD. The experiments show that cat eye effect surely exists in the optoelectronic detectors. With cat eye effect, the target with optoelectronic detectors could be detected and classified. In the experiment, the ratio of the laser power reflected from the CCD detector surface and the input laser power is about 4%. Though the experiments are simple and its distance between the laser and the detector is short, its way of target classifying can be extended to the long range applications.
