The influence of incident polarized light, refractive index, and size parameter of the scatterer on achievable resolution and contrast (image quality) of polarization-gated transillumination imaging in turbid media is reported here. Differential polarization detection led to significant improvement of image quality of an object embedded in a medium of small-sized scatterers (diameter D λ , isotropic scattering medium, anisotropy parameter g 0.2 ), especially using circular polarization. In contrast, for anisotropic scattering media composed of larger-sized scatterers ( D λ , g 0.7 ) , the improvement in image quality was less pronounced using either linear or circular polarization gating when the refractive index of the scatterer was high ( n s = 1.59 ) , but for a lower value of refractive index ( n s = 1.37 ) , image quality improved with the differential circular polarization gating. We offer a plausible explanation for these observations.
