POLARIZATION-CORRELATION MICROSCOPY OF HUMAN LIQUID POLYCRYSTALLINE FILMS IN INFERTILITY DIAGNOSIS

A new azimuthally stable polarimetric method for processing of microscopic images of optically anisotropic structures of different biological layers blood plasma is proposed. A new model of phase anisotropy definition of biological tissues by using superposition of Mueller matrices of linear birefringence and optical activity is proposed.

Polarization-interference mapping of biological fluids polycrystalline films in differentiation of weak changes of optical anisotropy

The theoretical background of the azimuthally stable method of polarization-interference mapping of the histological sections of the biopsy of the prostate tissue on the basis of the spatial frequency selection of the mechanisms of linear and circular birefringence is presented. The diagnostic application of a new correlation parameter – complex degree of mutual anisotropy – is analytically substantiated. The method of measuring coordinate distributions of complex degree of mutual anisotropy with further spatial filtration of their highand low-frequency components is developed. The interconnections of such distributions with parameters of linear and circular birefringence of prostate tissue histological sections are found. The objective criteria of differentiation of benign and malignant conditions of prostate tissue are determined
