对几种典型目标的后向散射光偏振度进行了测量和分析。基于探测光的Stokes矢量描述,利用接收光路和发射光路的一体化设计,设计了典型目标偏振特性的激光探测实验装置;在不同偏振光入射角、不同粗糙度参数以及不同表面材质的条件下,对几种典型目标后向散射光的偏振度进行了测量;在实验的基础上对偏振度测量数据进行了双高斯拟合和分析,得出了目标后向散射光偏振度与双高斯函数基本吻合以及基于后向散射光偏振度可以区分不同属性目标的结论。
The polarization degrees of backscattered light of several typical targets were measured and analyzed. Based on the stokes vector description of the probe light, a laser detection experiment device with typical target polarization characteristics is designed by using the integrated design of the receiving light path and the emitting light path. Under the conditions of different incident angles of polarized light, different roughness parameters and different surface materials, The polarization degree of several typical target backscattered light was measured. Based on the experiment, the Gaussian fitting and analysis of the polarization measurement data were carried out. The polarization degree and the double Gaussian function of the target backscattered light were obtained Anastomosis, and the conclusion that targets can be distinguished based on the degree of polarization of backscattered light.
