WebAn example of such a BRDF can be found in Ref. [13]. Analytical BRDFs are typically derived using either physical optics or geo-metrical optics. Physical optics BRDFs rely on the electromagnetic physical optics approxima-tion [14,15] (known as the Kirchoff approximation in optics) to predict the scatter from rough surfaces. WebOptical roughness was introduced into the bidirectional reflectance distribution function (BRDF) model to simulate the reflectance characteristics of thermal radiation. The optical …
