摘要

When laser light is incident on biotissue, the multiple reflection and scattering occur, which may cause the polarization state of laser speckles to have some changes. In this paper, we present an experiment study of the state of polarization of speckles generated from a multi-effect simulated biotissue, i.e., diffuse having multi-effects, via transmission, illuminated by a linearly polarized laser beam. It is found that in the case of non-multieffect diffuser the resulting speckles are linearly polarized as that of the illuminating beam. However, the state of linear polarization degenerates into an average elliptical polarization for the multi effect diffuser, and the degeneration increases as the multi-effect is stronger.
