Laguerre-Gaussian (LG) beams carrying orbital angular momentum (OAM) haveshown promise in deep tissue imaging, medical diagnostics, and opticalcommunication due to their robust propagation properties through scatteringmedia. However, an exact model that provides a mechanism for the enhancedscattering properties of LG beams over Gaussian beams has not been establishedtill date. Here, we examine this issue by studying the propagation of polarizedvortex beams transmitted through tissue-like turbid scattering media. Wedemonstrate that the intensity profile has a much more profound effect ondepolarization than the phase profile for LG beams. Our results indicate thatthe observed stronger propagation for the higher order LG beams is due to ahigher anisotropy factor g as seen by the incident beam. This insight isexpected to contribute towards building a complete picture of light transportin the presence of scattering, as well as guide optimization of the intensityand polarization structure of light for use in biomedical applications.
