Paper Abstract

An experiment measuring system is introduced. Angle-resolved single-band and multispectral bidirectional reflectance distribution function measurements are operated in ultraviolet band. Hemisphere spectral reflectivity of some samples is measured. An optimizing modeling method, particle swarm optimization (PSO) is used to model the laser BRDF data of typical samples. The results are fitted with the models developed above using optimize algorithm to get the parameters. Spectral BRDF of samples calculated with the model are in good agreement with the measured data. And these studies about measuring and optimizing modeling of typical roughness target samples in ultraviolet band have significant meanings in a lot of related fields.
