Abstract

A theoretical basis for the method of polarization-phase mapping of optically thin polycrystalline films of human biological fluids is given. The coordinate distributions of the magnitude of the phase shifts and the polarization-inhomogeneous microscopic images of polycrystalline films of the synovial fluid of the human joint are investigated. In the framework of the statistical (statistical moments of 1st-4th order), correlation (dispersion and kurtosis characterizing autocorrelation functions) and fractal (dispersion, characterizing the logarithmic dependencies of power spectra) approaches, objective criteria for the distribution of local contrast values are established. The possibility of differentiation of weak changes in the optical anisotropy of synovial fluid films in patients with different severity of the pathology of the knee joint has been determined. Comparative studies of the accuracy of this method and the traditional method of polarization mapping.
