Abstract

We report a theoretical study on the determination of three optical properties from spatially resolved reflectance calculations. In particular, the reduced scattering coefficient μ_s^′, the absorption coefficient μ_a, and the recently defined phase function parameter σ are identified. The solution of the inverse problem is based on the principal component analysis of a large set of reflectance profiles that were calculated using an analytical solution of the radiative transfer equation. Different phase function types were studied to test the method in the range of 0.63 mm⁻¹≤μ_s^′≤4.2 mm⁻¹ and 0.002 mm⁻¹≤μ_a≤0.1 mm⁻¹. For curves impaired with noise, we were able to reconstruct μ_s^′ and μ_a with relative median errors of 2.5% and 12%, respectively, and σ with an absolute median error of 0.04.
