1 November 1990 BRDF measurements for contamination assessment in a spacecraft environment
Author Affiliations +
The design of a scatterometer used for in situ studies of optical surface contamination is reviewed, and dual-wavelength (0.633, 10.6 micron) BRDF measurements are presented which were made on molecular contaminants adsorbed onto cryogenically cooled mirrors. The results are compared to others obtained from the literature, and the BRDF increase from contaminants is analyzed using a simple theory based on Rayleigh scattering.
