Bi-directional Reflectance Distribution Function

            The Bi-directional reflectance distribution function (BRDF) describes how a surface would send light when illuminated from different directions. The BRDF is one of the crucial parameters needed in radiative transfer modeling and remote sensing. In recent years, we have made extensive BRDF measurements on various types of particles from perfect spheres to natural sediments. Below is a list of papers developed during our ONR supported BRDF research programs:
