Abstract:
Considerable difficulties of accurate post-mortem interval (PMI) estimation are related to impact of large number of both external and internal factors on posthumous processes development, that is why PMI estimation is one of the main problems in forensic practice. There are many new optical polarimetric methods of biological tissue structure assessment, which ones are the most perspective in PMI estimation. The purpose of the work is to develop and to test the method of two-dimensional Stokes-polarimetric mapping of biological layers autofluorescence for PMI estimation by statistical analysis of postmortem changes dynamics of the coordinate distributions values of polycrystalline films of liquor (PFL) images laser-induced fluorescence polarization intensity.
