Paper Abstract

A new approach for monitoring temporal changes in the optical anisotropy of the human eye tissue after death was proposed. The basis of the research study assigned degree of depolarization of laser radiation, converted collagen networks vitreous of the eye.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 1st-4th 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.
