Wavelet analysis of Jones-matrix images corresponding to polycrystalline networks of biological crystals in diagnostics of tuberculosis
Determined in this work are analytical interrelations between orientations of optical axes and birefringence of biological crystals as well as characteristic values of elements in the Jones matrix for flat layers of polycrystalline networks, which determine conditions for formation of polarization singularities in laser images. Performed is a complex statistical, correlation and fractal analysis of distributions for the amount of characteristic values inherent to the Jones matrix elements describing layers of saliva taken from a healthy patient and that sick with tuberculosis. The authors have ascertained objective criteria to differentiate optical properties of polycrystalline networks of human saliva in various physiological states.

The degree of mutual anisotropy of biological liquids polycrystalline nets as a parameter in diagnostics and differentiations of hominal inflammatory processes
To characterize the degree of consistency of parameters of the optically uniaxial birefringent protein nets of blood plasma a new parameter β complex degree of mutual anisotropy is suggested. The technique of polarization measuring the coordinate distributions of the complex degree of mutual anisotropy of blood plasma is developed. It is shown that statistic approach to the analysis of the complex degree of mutual anisotropy distributions of blood plasma is effective during the diagnostics and differentiation of an acute inflammatory processes as well as acute and gangrenous

Autofluorescent polarimetry in diagnostics of endometriosis and infertility
A new information about optical technique in diagnostics for the endometrium structure has been proposed. The model of Mueller-matrix description of mechanisms responsible for optical anisotropy of these objects (optical activity, birefringence as well as linear and circular dichroism) has been suggested. The ensemble of informationally topical azimuthally stable Mueller-matrix invariants has been determined. Using the statistical analysis of the distribution parameters, the objective criteria for differentiation of endometrium taken from healthy women and patients with endometriosis were determined. From the viewpoint of probative medicine, the operational characteristics (sensitivity, specificity and accuracy) of the information-optical method applied to Mueller-matrix mapping of endometrium histological section have been found and its efficiency in diagnostics of endometriosis and infertility has been demonstrated

Azimuthally invariant Mueller-matrix mapping of biological optically anisotropic network
A new technique of Mueller-matrix mapping of polycrystalline structure of histological sections of biological tissues is
suggested. The algorithms of reconstruction of distribution of parameters of linear and circular dichroism of histological
sections liver tissue of mice with different degrees of severity of diabetes are found. The interconnections between such
distributions and parameters of linear and circular dichroism of liver of mice tissue histological sections are defined. The
comparative investigations of coordinate distributions of parameters of amplitude anisotropy formed by Liver tissue with varying severity of diabetes (10 days and 24 days) are performed. The values and ranges of change of the statistical (moments of the 1st β 4th order) parameters of coordinate distributions of the value of linear and circular dichroism are defined. The objective criteria of cause of the degree of severity of the diabetes differentiation are determined
