Abstract

The features of the use of polarized radiation in the problems of metrology of optical-geometric and structural parameters of light-scattering objects of various physical and chemical nature are described. Experimental situations are revealed that are most relevant for the study of optically anisotropic dispersed media containing particles of various shapes, sizes and orientations. The analytical dependence of the value of the fourth Stokes parameter of circularly polarized radiation passing through a layer of oriented particles with an optical thickness τ < 3 on the degree of their orientation is determined. A method is proposed for assessing the degree of orientation of macromolecules in polymer films, the conformation of biopolymers from the values of f₂₂ components at any scattering angles, and determining the shape of macromolecules at scattering angles greater than α > 30°. Experimental conditions and methods of matrix polarimetry of the process of corrosion of the free surface of a metal and its corrosion under a paint-and-lacquer coating are presented.
