A polarization-sensitive Monte Carlo model is used to investigate differently polarized light illuminations on their degree of polarization (DOP) depth evolution in a semi-infinite scattering medium. The three-dimensional simulations show that circular polarized light maintains its initial polarization state longer than elliptical or linear polarized light. It was revealed that elliptical polarization can be tuned so that its DOP depth evolution can be precisely chosen between the penetration depths of linearly and circularly polarized light.
