摘要
为了研究漫反射物体及涂层与基底材料的后向散射激光偏振特性,针对混凝土地面、篷布和涂漆金属目标样片开展了后向散射激光偏振特性研究,利用斯托克斯参量测量方法,对目标样片进行了测量。实验结果表明:高漫反射目标后向散射光的偏振特性基本不随入射角度的变化而改变;在偏离镜像角度处,涂层对涂漆金属目标样片后向散射激光偏振特性的影响比基底材料的影响更明显。
To get the laser backscattering polarization characteristics of diffuse reflecting objects, coat material and substrate material,a correlative study on concrete, canvas and painted metal samples is conducted based on the Stokes parameter method. The results show that the backscattering polarimetric characteristic of high diffuse reflection samples changes little as the incidence angle increases, and the influence on polarization of painted sam- ple exerted by the coat is stronger than by the substrate material.
