Interrelation between the polarization state of local zones of the object field and the inclination angles of skin epidermis plates has been found within a single-scattering approximation. The technique for the polarization reconstruction of coordinate distribution of the inclination angles of surface micro-irregularities referred to the skin epidermis has been suggested. The first-to-fourth orders statistics for the optical geometric properties of rough surface of physio-logically normal and pathologically changed skins has been analyzed. It has been shown that the microrelief of the healthy skin surface has a fractal angular structure. Pathological changes cause random distribution of the inclination angles of the skin surface micro-irregularities.

Keywords: biological tissue, statistical moments, power spectrum.
