Paper Abstract

In this paper we present the study on reflection speckles. We have investigated the polarization properties of reflection laser speckles and the relative correlation between speckle patterns of different polarization. If the diffuser is a pure glass it is found that reflection speckles are linear--polarized as that of the incident beam. This state of linear polarization of the speckle field degenerates into a state of average elliptical polarization as the diffuser surface is coated with a layer of flat white paint, as simulated biotissue; the degeneration increases as the thickness of the paint increases. The state of polarization is also a function of the scattering angle, and the maximum linear polarization always occurs at the direction of specular reflection of the average diffuser surface.
