Methods and systems of polarization reproduction and analysis of the biological layers structure in the diagnosis of pathologies

Abstract

Methods and automated systems of direct and Mueller-matrix reproduction of optical anisotropy parameters (orientation of the fast axis and optical phase shift) of two-layer optically thin biological structures are represented. The pathological condition objective assessment is based on the multi-parameter analysis of statistical characteristics (estimates of starting moments of the first order and estimates of the central moments of the second to fourth orders) determined for the coordinate, autocorrelation distributions and logarithmic dependences of the power spectra of the distributions of reproducible anisotropy parameters biological layers. The accuracy of the suggested methods of polarized phase reproduction and analysis of the biological layers structure within the range of 83.7% to 95.3% is estimated.
