Abstract
Reflectance models based on physical optics and geometrical optics
are studied. Specifically, the authors consider the Beckmann-Spizzichino
(physical optics) model and the Torrance-Sparrow (geometrical optics)
model. These two models were chosen because they have been reported to
fit experimental data well. Each model is described in detail, and the
conditions that determine the validity of the model are clearly stated.
By studying reflectance curves predicted by the two models, the authors
propose a reflectance framework comprising three components: the diffuse
lobe, the specular lobe, and the specular spike. The effects of surface
roughness on the three primary components are analyzed in detail
