The present work is devoted to investigation of mechanisms of optical anisotropy of biological tissues polycrystalline networks and laser polarization fluorescence. The model of complex optical anisotropy, which takes into account both linear and circular birefringence, as well as linear and circular dichroism of fibrillar networks of histological sections of women reproductive sphere is proposed. The data of statistical, correlation and fractal processing of coordinate distributions of laser polarization fluorescence is provided. The technique of azimuthally invariant Mueller-matrix mapping of laser polarization fluorescence of protein networks in the tasks of differentiation of benign and malignant tumors of uterus wall is elaborated.
The results of investigation aimed at analysis of coordinate distributions for azimuths and ellipticity of polarization (polarization maps) in laser images of three types of phase-inhomogeneous layers are presented in this research, namely: rough, ground and bulk-scattering layers. Three groups of parameters: statistical moments of the first to fourth orders, autocorrelation functions, logarithmic dependences for power spectra related to distributions of azimuths and ellipticity of polarization inherent to phase-inhomogeneous layers laser images are suggested to characterize polarization maps for all the types of phase-inhomogeneous layers. The criteria for diagnostics and classification of phase-inhomogeneous layers optical properties are ascertained.
To characterize the degree of consistency of parameters of the optically uniaxial
birefringent protein fibrils nets of biological tissues a new parameter - complex degree of
mutual anisotropy is suggested. The technique of polarization measuring the coordinate
distributions of the complex degree of mutual anisotropy of biological tissues is developed. It
is shown that statistic approach to the analysis of complex degree of mutual anisotropy
distributions of skin derma of various optical thicknesses appears to be more sensitive and
efficient in differentiation of physiological state in comparison with investigations of complex
degree of mutual polarization of the corresponding laser images.
