Quasi-scalar description of multiple scattered speckle fields: empirical microstatistics of polarization states

摘要

Phenomenological description of the local polarization structure of multiple scattered speckle patterns is discussed. Different approaches to these structures characterization are reviewed. Experimental results obtained with multiple scattering model objects show that statistical properties of local polarization parameters can be described by using the `quasi-scalar' approach; in this case multiple scattered speckle pattern is interpreted as the superposition of two orthogonally polarized fully developed statistically independent components.
