Paper Abstract

Infrared spectra of two 'black' baffle coatings, which were made both with and without large SiC scattering centers, demonstrate the strong attenuation of specular reflectance caused by scattering. This attenuation is described quantitatively by a reflecting layer model for rough, thick absorbing coatings. Infrared spectra and BRDFs of a very rough aluminum surface, which is a nearly perfect diffuse reflector, demonstrate how the surface scatter changes with wavelength from a region where specular reflection dominates to the region where scatter dominates.
