Abstract

Light depolarization due to multiple scattering in tissue is an interesting bio-medical issue. The bio-tissue is made of anisotropic molecules. Using a simple ellipsoid model, the polarization property of single anisotropic bio-molecule has been investigated theoretically. We extend this theory to a bio-tissue that is modeled as a system of non-correlated anisotropic molecules. Based upon a statistical model of anisotropic distribution, the scattering depolarization effects are investigated. The simulated molecular orientation-dependent single scattering depolarization Ds (1) and the double scattering depolarization Ds (2) are reported. Ds (2) contribution is more important for high density scattering medium. This theory has provided a simulation tool for investigating the depolarization effect in the highly scattering bio-medium.
