For different kinds of applications, mainly focused on probing/imaging of complex media, management of light scattering remains a challenge. Numerous studies have proven that the statistical laws followed by the intensity patterns and the polarimetri

Statistical optics provides a direct tool to determine correlation between interfaces of a multilayer. It is shown how this correlation controls the polarization degree of scattering. Coatings microstructure can be characterized with this procedure.
