Experimental test of a time-dependent inverse radiative transfer algorithm for estimating scattering parameters

Abstract

Experimental and numerical simulation tests have been performed on an inverse radiative transfer algorithm designed to estimate the Legendre moments of the single-scatter phase function. The algorithm makes use of time-resolved measurements of the backscattered radiance from a plane-geometry semi-infinite medium. It was shown possible, even in the presence of experimental noise, to estimate the single-scatter albedo with a relative error of < 1%. Estimates of the asymmetry factor were found to be less accurate (< 12%) and estimates of higher moments to be impractical.
