Abstract

A theoretical treatment based on electromagnetic theory has been developed for the dependence of depolarization of linearly and circularly polarized light on size parameter of scatterer. The model reproduces the earlier results for the dependence of depolarization of circularly and linearly polarized light on scatterer size parameter. Further, the results obtained from this model show that for a given scatterer size parameter, a change in the value of ratio of refractive index of scatterer to that of the surrounding medium also significantly affects the degree of depolarization of both linearly and circularly polarized light. These results have been experimentally verified and can have important consequences for polarization gated optical imaging.
