Abstract

Polarimetric investigation of fully resolved speckle patterns provides a direct measure of the joint distribution of Stokes vector elements. In the case of highly diffusive media, Gaussian statistics are usually invoked to describe the field distribution and subsequently determine the polarization distribution. However, it has been shown that various types of globally unpolarized field distributions can arise in practice, and that second order polarization correlations can be used as a means for discriminating these various ensembles. We examine polarization correlations as they relate to the thickness and morphological structure of bulk scattering media. We also comment on the usefulness of the complex degree of mutual polarization as a discriminator in this regime.
