Paper Abstract

1. The polarization types and forms of a set of object field correlation zones is shown to exhibit a certain structure. 2. In the case of a dielectric rough surface, the set of boundary field correlation zones is shown to exhibit random polarization directions. It is shown that for single scattering, the probability density of the polarization directions is closely related to the slope distribution function of the quasi-plane roughness elements. 3. Damaged subsurface optically inhomogeneous layers observed in ground transparent samples are shown to manifest itself by statistically distributed polarization directions and ellipticities in the object field correlation zones. 4. The polarization directions and ellipticities of speckles are shown to vary over a wide range in the case of volume scattering. As the optical thickness increases, the polarization structure of multiply scattered coherent radiation tends to an equiprobable distribution of polarization types and forms in completely polarized local elements. 5. A fine polarization structure is revealed in local speckles of the scattered coherent radiation. Mechanisms of its formation in boundary field correlation zones and its transformations during propagation of coherent radiation are studied.
