Depolarization of polarized light transmitting through a turbid medium is known to decrease with increasing value of anisotropy parameter g of the medium. We have observed that for turbid media comprised of scatterers having size parameter (X) and relative refractive index ratio (m) in the range [0.05(m−1)X2.5], although for a given value of X, a decrease in the value of m leads to higher g, depolarization also increases. This anomalous behavior arises because the depolarization characteristics of anisotropic scattering media (a928b97416e5bf10ead6b13"" title=""Click to view the MathML source"">g0.7) comprised of low refractive index scatterers [(m−1)1,(m−1)X1] are much similar to that for Rayleigh scatterers.
