Polarization Reconstruction Of Birefringence Of The Polycrystalline Component Of Biological Tissues With Different Damage Durations

By Mueller-matrix mapping of changes in the distribution of the magnitude of matrix invariants characterizing the degree of crystallization of histological sections of the brain, liver and kidney, the forensic medical criteria were determined and the interval for determining the damage duration of 24 hours with an accuracy of 45min. - 50 min. was established. For azimuthally invariant polarization mapping of changes in the distributions of Mueller-matrix invariants characterizing the optical activity of molecular complexes of histological sections of the brain, liver, and kidney, forensic medical criteria were developed for the first time and accuracy was improved to 35 min. - 40 min. in the interval for determining the damage duration period of 72 hours. For highly accurate objective determination of the damage duration in a long time interval (1 hour - 120 hours), a polarization tomography method has been developed (reproducing the distributions of birefringence of fibrillar networks of histological sections of internal organs), which provides an accuracy of 25 minutes. (1 hour - 24 hours) to 45 minutes (24 hours - 120 hours).
