Abstract

This paper focuses on the absorption effect due to pathological changes. Using Monte Carlo simulation on our previously proposed sphere-cylinder-birefringence model (SCBM), and forward scattering experiments on phantoms containing polystyrene microspheres, well-aligned glass fibers and ink solution, we investigate how depolarization, retardance and diattenuation change with tissue absorption by decomposing the Mueller matrix using Mueller matrix polar decomposition method. According to the simulation and experimental results, this paper presents the influence of absorption on polarization scattering process from three aspects: firstly, the absorption depresses the depolarization contributed by the spherical and cylindrical scatterers; secondly, it decreases the retardance due to the anisotropic cylinder; thirdly, the increasing absorption enhances the diattenuation from cylindrical scatterers.
