New parameter for describing and analyzing the optical-anisotropic properties of biological tissues

Abstract

To characterize the degree of similarity inherent to parameters of the optically uniaxial birefringent protein-¯bril networks of biological tissues, a new parameter — complex degree of mutual anisotropy — has been o®ered. The technique of polarization measuring the coordinate distributions of the complex degree of mutual anisotropy of biological tissues has been developed. It has been shown that statistical approach to the analysis of complex degree of mutual anisotropy distributions for biological tissues in various morphological and physiological states and for di®erent optical thicknesses appears to be more sensitive and e±cient in di®erentiation of physiological state, as compared to investigations of complex degree of mutual polarization in the corresponding laser images.
