The characterization of material reflectance properties is important in the analysis of hyperspectral and polarization
imagery as well as accurate simulation of such images. This paper merges the results of empirical reflectance property
(spectral pBRDF) measurements with detailed model based simulations. The empirical data are collected with a
laboratory spectroradiometer as well as an RIT-developed spectro-polarimetric imaging goniometer. The modeling uses
an adaptation of RIT's Digital Imaging and Remote Sensing Image Generation (DIRSIG) model to capture the radiative
transfer in rough surfaces with micron-scale features. Measurements and model results for several man-made materials
under various conditions are presented.
