Results Of A CO[sub]2[/sub] BRDF Round Robin

The results of a nationwide CO 2 BRDF round robin are presented. This study was conducted as a follow-on to a 1988 0.6328 ,um BRDF round robin.(1) Four master samples ranging in roughness from a diffuse surface to a 45 A rms mirror were measured at six scatter facilities. BRDF data in the forward direction for an incidence angle of 10° is compared from all participating facilities for the four samples. Unfortunately, the samples were lost during shipment between scatter facilities, and it was not possible to complete measurements at the 14 planned facilities.
