The influence of size of the scatterer on the image contrast for polarization-based range-gated imaging in turbid media is investigated here by Monte Carlo method. Circularly polarized light would be more efficient to eliminate the noise photons for both the isotropic medium as well as the anisotropic medium, as compared with linearly polarized light. The improvement in contrast is pronounced for isotropic medium using either linear or circular polarization. The plausible explanations for these observations are also presented.
