Analysis of polarization speckle for imaging through random birefringent scatterer

Propagation of acoherent light through ananisotropic random medium generates randomly polarized field, known aspolarizationspeckle. In this paper, an experimental technique is proposed and demonstrated to recover the transmittance of a polarized object frompolarizationspeckle. Recovery of the polarized object frompolarizationspeckle is made possible by combining the far-field intensity correlation of the objectspeckle with off-axis holography to determine the complexcoherencefunction of thespeckle. The desired objectspeckle which is uniformly polarized is filtered from thepolarizationspeckle using apolarizer. The results are compared with the case where the complexcoherencefunction is determined in the absence of thepolarizer.
