Abstract
A large variation in bidirectional reflectance distribution function (BRDF) for certain GaAs surfaces is proposed as the basis for a variable BRDF reference material. Such a material would provide a range of reference values as opposed to the discrete values of diffuse reference materials. The effect is reasonably stable and uniform, and is most likely the result of a weak grating effect caused by surface striations.
