摘要
散射光偏振度在大气气溶胶、大气污染的遥感探测中有重要的应用价值。通过求解Mueller矩阵及偏振度,讨论了当激光器输出波长处于近红外波段806 nm时,散射介质的粒子数浓度对散射光偏振度的影响。给出了散射光的偏振度与散射介质的粒子数浓度之间的变化关系,为使用散射光偏振度研究大气遥感提供了新途径。
The p olarization degree of the scattered light has particular ability in the detection of remote sensing for the aerosol and pollutant gas. By calculating the Mueller matrix and the polarization degree, the effects of the concentration of the scattered medium on the polarization degree are studied when the scattered light at 806 nm near infrared. The relationship of polarization degree of the scattered light and particle beam numerical density of scattered medium is presented. Based on the result, the polarization degree can be used to study the atmosphere remote sensing.
