Abstract. Represented in this work are theoretical basics for description of fields created by scattered coherent radiation with using the new correlation parameter -degree of local depolarization (DLD). The authors have adduced data of measurements of coordinate distributions for DLD in laser images of healthy and pathologically changed skin of a rat. Investigated are the values and ranges of changes in statistical (moments of the first to fourth orders), correlation (correlation area) and fractal (slopes and dispersion of extremes of logarithmic dependences for power spectra) parameters of coordinate distributions for DLD. Defined are objective criteria for diagnostics of oncological changes in the structure of rat skin.

“…When multiple scattering takes place, polarization information upon the BT structure becomes ambiguous and, as a consequence, loses its diagnostic sense [9,10,12,16,19]. This phenomenon got the name of depolarization of optical radiation due to statistical averaging the polarization states [12,16,19].…”

The complex statistical and fractal analysis of phase properties, inherent to birefringence networks of liquid crystals consisting of optically-thin layers, prepared from synovial fluid taken from human joints, is performed in this work. Within the framework of a statistical approach, the authors have investigated values and ranges for changes of statistical moments of the 1-st to the 4-th orders that characterize coordinate distributions for phase shifts between orthogonal components of amplitudes inherent to laser radiation, transformed by synovial fluid layers, for human joints with various pathologies. The correlation criteria for differentiation of phase maps, describing pathologically changed liquid-crystal networks, have been ascertained. In the framework of the fractal approach, dimensions of self-similar coordinate phase distributions as well as features of transformation of logarithmic dependences for power spectra of these distributions for various types of human joint pathologies are determined.

Abstract. The work is aimed at investigation of diagnostic efficiency of a new azimuthally stable Mueller-matrix method for analysis of laser autofluorescence coordinate distributions corresponding to biological tissue histological sections. A new model of generalized optical anisotropy observed in biological tissue protein networks has been proposed to study the processes of laser autofluorescence. The influence of complex mechanisms of both phase anisotropy (linear birefringence and optical activity) and linear (circular) dichroism has been taken into account. The interrelations between the azimuthally stable Mueller-matrix elements characterizing laser autofluorescence and different mechanisms of optical anisotropy have been ascertained. The statistic analysis of coordinate distributions inherent to these Mueller-matrix rotation invariants has been proposed. Thereupon the quantitative criteria (statistic moments of the 1 st to 4 th orders) of differentiation of histological sections of uterus wall tumor -group 1 (dysplasia) and group 2 (adenocarcinoma) have been found.
