Abstract :
In this contribution, new paradigms of laser interaction and imaging through scattering media are presented. Specifically, the imaging potential of efficient optical polarimetric techniques, for active imaging through scattering media has been studied. The depolarization of backscattered polarized laser light, based on the Mueller-matrices formalism, has been investigated. The experimental results indicates clearly that, scattered photons from disperse media maintain a high degree of polarization. As a result, image quality and target recognition can be improved significantly.
