Abstract
Studies on propagation of linearly and circularly polarized vortex beams in tissue-like forward scattering turbid media revealed longer survival of vortex beams with higher topological charge (l). It is shown that an increase in the effective anisotropy parameter of scattering as seen by vortex beams having higher topological charge (l) is responsible for the observed longer survival of vortex beams in tissue and tissue-like turbid media. These findings may open up interesting avenues towards achieving larger depth of imaging in biological tissues by appropriately tailoring orbital angular momentum and spatial polarization states of vector vortex beams.
