The optical model of polycrystalline networks of histological sections of rectum wall is suggested. The results of investigating the interrelation between the values of statistical (statistical moments of the 1 st -4 th order) parameters are presented. They characterize the coordinate distributions of the fourth parameter of Stokes vector of Fourier transforms of laser images of rectum wall histological sections and oncological changes. The diagnostic criteria of rectum cancer are determined.

“…For performing a number of diagnostic tasks in gynecology, oncology, dermatology, forensic medicine, etc., the laser polarimetry technique was suggested and successfully tested in a series of works [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. This technique enables to determine the interconnection between optical anisotropy of biological object and its physiological state.…”

The optical model of polycrystalline networks of vitreous body histological sections is suggested. The results of investigating the interrelation between the values of statistical (statistical moments of the 1 st -4 th order), correlation (correlation area, asymmetry coefficient and autocorrelation function excess) and fractal (dispersion of logarithmic dependencies of power spectra) parameters are presented. They characterize the coordinate distributions of phase shifts between the orthogonal components of the amplitude in the points of laser images of histological sections of vitreous body and temporal dynamics of optical anisotropy of this biological object. The diagnostic criteria of death coming prescription are determined.

“…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].…”

“…This phenomenon got the name of depolarization of optical radiation due to statistical averaging the polarization states [12,16,19]. On the other hand, when scattered is coherent laser radiation, the speckle field with 100 % degree of local polarization is formed [8].…”

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.
