Outline of Final Research Achievements |
Samples that consisted of suspensions of micro particles in media were selected as a model of biological organization. When the sample was illuminated by a thin light beam, the polarization state of scattered light exiting from the sample surface was investigated. It was proved theoretically that the symmetry of multiple scattering in media reflects that for scattering by single particles. Numerical simulations revealed the followings: for spherical samples, the diattenuation and the retardance become greater as the scattering angle is closer to 180 deg.; for slab samples, similar behaviors are observed with respect to the distance from the illumination point; the optical rotation increases in proportion to the distance for chiral media; the polarization properties are dependent on the azimuth in birefringent media. These numerical results were verified by experiments.
