Paper Abstract

Electromagnetism theory is used to calculate the effect of aperture receiver on the polarization of scattered light. The result is a spatial average (several speckle grains within the aperture) responsible for a depolarization process similar to that of temporal situation. The associated DOP is calculated versus surface parameters (roughness, slope...) and reveals new signatures for identification of samples. The DOP is also calculated in a multi-scale manner, that is, versus the receiver aperture. Examples are given to separate surface and bulk scattering.
