    Abstract

    Abstract: The polarization state of the object is altered due to the surfaces of the optical lens in the polarization CCD camera with large viewing field, and the variation relate to the field of view, azimuth angle and polarization states of the observed beams. The polarimetric accuracies limit the application of polarization remote sensing due to the polarization phenomenon of the instrument. To overcome the problems, calibration method of the model parameters and retrieval of the polarization information is introduced based on the polarimetric calibration model. In order to verify the calibration method feasibility, the Degree of Linear Polarization (DOLP) comparison tests of the calibrated polarization CCD camera with large viewing field compared with the high-precision variable polarization light source have been carried out. Experimental results show that the DOLP accuracy of the calibrated polarization CCD camera is better than 1.18% at the 0°, 15° and 25° field of view. The method of polarimetric calibration would get rid of the influence of polarization phenomena of the polarization CCD camera, and contribute to fundamental basis for the quantitative application of polarization remote sensing information for the Chinese polarized satellite sensor.
