This book presents experimental investigations and digital image processing highlighting the
interaction of polarized radiation with phase-inhomogeneous and optically anisotropic
biological layers. The promising and efficient use of vector-parametric description of the
formation of polarization-inhomogeneous object fields is noted. Applications of a set of
Mueller-matrix polarimetry methods are highlighted. The book includes- structural and logical
scheme of multi-parameter (singular interference and layer-by-layer Stokes-polarimetric)
polarization-correlation study of the structure of distributions of the number of singularities
maps of local contrast of interference distributions and layer-by-layer maps of microscopic
polarization azimuth and ellipticity determination of relationships between changes in the
magnitude of statistical parameters characterizing polarization-correlation distributions and
pathology of prostate tumors.
