We measured in-plane bidirectional-reflectance-distributionfunction (BRDF) profiles for specular, haze and Lambertian samples using a converging light beam and a photopic photodiode. The results were validated by comparing the hemispherical reflectance values calculated from BRDF data with direct measurements by the use of integrating spheres, whereby an agreement to within 2 % was achieved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
