Abstract
A scheme is derived for deducing the Legendre moments of the optical scattering function of a homogeneous, optically thick planar medium. The radiometer need only scan the backscattered light intensity over the azimuthal angle, for a fixed polar angle, at times long after irradiation of the scattering volume by a laser pulse.

- The equation follows directly from Eq. (26) of Ref. 15, except the optical thickness of the target for the validity of diffusion theory has been taken to be X; for the azimuthally symmetric (m = 0) analysis, however, a better approximation is to replace X with X + 4.2D°/ ν to account for two optical extrapolation distances.

- For small values of X/D°, especially when the scattering is strongly anisotropic, the results of Ito and Furutsu become suspect because their distributed source arising from first collisions [Ref. 8, Eq. (13)] is assumed to be isotropic.
