been recognized as a powerful tool for screening thin (nondepolarizing) histological sections of biological tissues [8, 9]. An interconnection between the statistical moments of the first to fourth orders characterizing Mueller-matrix elements and the parameters of linear birefringence of biological tissues, such as fibrillary protein networks, has been established. This provides a unique possibility for the diagnosis of cancerrelated abnormalities in biological tissues [8-13]. Nevertheless, the various mechanisms of optical anisotropy of biological tissues/layers [14, 15] and the presence of a variety of optically anisotropic biological liquids (including
