Abstract

Bidirectional reflectivity distribution function (BRDF) measurement results are reported for the monostatic case and for small bistatic angles for several low-scatter diffuse materials illuminated at the 1.064 &mgr;m and 532 nm wavelengths. Materials such as ESLI Vel-Black, Edmund Scientific flocked paper, and 2% Spectralon were measured. All materials were measured using both co-polarized and cross-polarized transmit-receive configurations. The MRDF/BRDF scatterometer at the Advanced Measurements Optical Range (AMOR) at Redstone Arsenal in Huntsville, Alabama was used for these measurements and is described here; this beamsplitter-based system can make BRDF measurements with incidence angles from 0 to 80° and with in-plane and out-of-plane bistatic angles from + 3.5° through -3.5°, including the monostatic point.
