Bezhenar I. Establishment of during the life time and prescription of inflicting bodily injuries based on the findings of laser polarimetry of biological tissues

The research has defined and substantiated theoretically correlations between a lifetime and postmortal abrasion formation and statistical (mean and dispersion) and spatial - frequency (dispersion of Log-log extremums of dependences of power spectra) parameters that characterize the coordinale distributions of intensity azimuths ellipticity phase shifts between the orthogonal components of a laser wave in skin images of biomanikins. Statistical criteria of differentiation of during the lifetime or postmortal origin of injuries of the human body skin. It has been demonstrated that the intensity of a histological sectionof human intact skin is distributed coordinately between values 320-270 of the histologic section of the human skin and an abrasion inflicted during the lifetime between values 80-45, of the histological section of the human skin with a postmortal abrasion between values 55-35. On comparing the mean data of the extremums of the power spectra for laser image of the histological sections of an abrasion inflicted during the lifetime with intact skin (the control) the difference is statistically significant. The same difference is detected on comparing a postmortal abrasion with the control is insignificant. Statistically averaged values of the distributions of the extremums for the power of the intensity of skin laser images, on juxtaposing the index of reliability between intact skin with an abrasion inflicted during the lifetime and a postmortal abrasion the difference is insignificant.
