Mueller matrix decomposition study on anisotropic medium including cylindrical scatterers and birefringent effect

摘要

In this paper, we study the cylindrical scatterers and birefringent medium as two anisotropic sources in the turbid medium by polarimetry method. Using Monte Carlo simulations on the anisotropic sample, we examine in detail the relationship between the retardance δ , depolarization ⊿ and the anisotropic microscopic structure and their interactions of each other by Mueller matrix decomposition method. The well-ordered cylinder scatter system can be regarded as a birefringent medium. If the orientation of the aligned cylindrical scatterers does not coincide with the extraordinary axis of the birefringent medium, the variation of total retardance in this cylinder-birefringence model would accord to the two pieces of birefringent medium overlapped together with angle between extraordinary axes.
