Paper Abstract

The scattered light of tissues provides abundant information about the tissues properties. In this paper, light propagation in anisotropic scattering medium was investigated experimentally and theoretically. To study the influence of fibrous structure on the propagation of polarized light in anisotropic medium, the transmitted light from a section of dentin was measured. The measured polarization property of the scattered light was related to the polarization direction of the incident light. Cylindrical scatterer was utilized to model the scattering of microstructure in dentin. The experimental results are compared with the simulation results. The results demonstrated that the microstructure in anisotropic medium has effect on both propagation direction and polarization of scattered light. Understanding the effects of microscopic structure on the polarized light scattering will aid to develop polarization dependent optical detection methods in anisotropic medium.
