Paper Abstract

The rate of randomization of linearly polarized light as a collimated polarized beam passes through scattering media was characterized by a diffusivity ((chi) ) (radians2/mean free path) in the angle space ((theta) ) describing orientation of the linear polarization: probability of orientation at an angle p((theta) ) equals exp[-(theta) 2/(2(sigma) 2)]/[(sigma) sqrt((pi) /2)] where (sigma) equals (chi) (tau ) and (tau) is the mean free path ((mu) sL) where (mu) s is the scattering coefficient (cm-1) and L is sample thickness (cm). The media studied were polystyrene microsphere solutions, liver, muscle, and skin. The (chi) for microspheres ranged from 0.80 - 0.03 for 300 - 6000 nm diameter, and was 0.28 for skin, 0.06 for muscle, and 0.003 for liver.
