Abstract

The rate of randomization of linearly polarized light as a collimated polarized beam passes through scattering media was characterized by a diffusivity (χ) [radians2/mean free path] in the angle space (θ) describing orientation of the linear polarization: probability of orientation at an angle p(θ) = exp(-θ2/(2σ2))/(σ sqrt(π/2)) where σ = χτ and τ is the mean free path (μsL) where μs is the scattering coefficient [cm-1] and L is sample thickness [cm]. The media studied were polystyrene microsphere solutions, liver, muscle, and skin. The χ for microspheres ranged from 0.80-0.03 ffor 300-6000 nm diameter, and was 0.28 for skin, 0.06 for muscle, and 0.003 for liver.
