Abstract:In the visible light range, the reflected light of ice contains a portion of polarized light, especially smooth ice often can make the detector obtain the reflection information that contains more polarization information. The fresh water ice and sea ice reflection information was measured, and combined with the angle information and spectral information, the difference in the polarized reflectance characteristics between them was analyzed. It was found that with the polarization degree as index, the difference in the relative reflectance between sea ice and water ice is larger, and at the same time ice shows its unique polarization characteristics. So that the polarization measurements can assist the existing remote sensing technology for better detection of the ice covering the earth’s surface.
