Abstract

A method is described for finding the optical properties (scattering, absorption, and scattering anisotropy) of a slab of turbid material using reflection and transmission measurements. Previously, it has been difficult or impossible to quantify a method’s intrinsic error due to restrictions on the boundary conditions, the scattering anisotropy, the ratio of scattering to absorption, or the thickness of the slab. By eliminating these constraints, the inverse adding-doubling method is applicable to turbid media with any optical thickness, albedo, or phase function and its intrinsic error may be quantified.
