26 February 2010 Helicity flip of the backscattered circular polarized light
Author Affiliations +
We study coherent and non-coherent backscattering of circularly polarized light from turbid media. We find that the sign of helicity of circular polarized light does not change for a medium of point-like scatterers and can change significantly for the medium with high anisotropy of scatterers. The helicity flip is observed when the light scattering is described in terms of the Henyey-Greenstein scattering phase function. The angular dependence of the sum of coherent and non-coherent parts of backscattering also exhibits a helicity flip.
