Modification of the particle-model theory of diffuse reflectance properties of powdered samples
Abstract
Equations are derived which describe the diffuse reflectance of a powdered sample in terms of its fundamental optical parameters on the basis of the rough-surfaced spherical particle model for a powdered sample. The major difference in the derivation compared with previous particle-model theories is that the assumption that a particle in a powdered sample scatters light equally in all directions is not used. The equations obtained are compared with those obtained from Melamed's theory and with experimental results.
