Abstract

Laser scattering by biopolymers and biotissues is studied the Stokes polarimetry method which permits obtaining exhaustive information on the changes in photometric and polarization characteristics of laser radiation resulting from scattering by various kinds of biological structures. Spatial and angular dependencies of scattering matrix elements are studied for albumin, lysocim mycopeptide, muscle and skin tissues, etc. The relative magnitudes of scattering indicatrices are found to be different for different biological objects. Is shown that the objects studied have the property of transformating the type and form of polarization of the incident laser beam. The fraction of depolarized radiation within the polarimeter field of view is shown to increase with the number of scattering events. The results obtained can be useful in developing noncontact methods for assessing the structures of biological tissues.
