We formulate a quantitative description of backscattered linearly polarized light with an extended photon diffusion formalism taking explicitly into account the scattering anisotropy parameter <i>g</i> of the medium. From diffusing wave spectroscopy measurements, the characteristic depolarization length for linearly polarized light, l<sub>p</sub>, is deduced. We investigate the dependence of this length on the scattering anisotropy parameter <i>g</i> spanning an extended range from −1 (backscattering) to 1 (forward scattering). Good agreement is found with Monte Carlo simulations of multiply scattered light.
