几种地物反射光的偏振特性

偏振测量具有很多普通的光强度测量不具备的优点，是研究地表、大气，探索太空的良好辅助手段。为了获得可见一红外偏振光谱，从而考察利用偏振遥感识别目标的可行性，采用求取斯托克斯参量的方法，分别对草地、黄色环氧板、沥青楼顶、绿帆布、水泥路面及铁板六个样品做了反射光偏振特性测量，并对它们的偏振光谱进行了详细比较，分析了其形成原因。结果表明偏振特性与目标的性质、测量波长、观测角度均有很大关系，偏振测量在遥感和目标识别方面具有重要的意义。

Polarization of Reflected Light by Earth Objects

Compared with the traditional luminosity and radiation remote sensing methods, polarization measurement has many unique advantages. To achieve visible infrared polarimetric spectra, the polarimetric spectra of six objects are measured with Stokes parameter method, including both natural objects and man made objects. Their polarimetric spectra are compared in detail and the forming mechanism are analysed, too. The results show the significance of polarization measurment in remote sensing and object discrimination.
