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.
