One-shot BRDF imaging system to obtain surface properties

Abstract The bidirectional reflectance distribution function (BRDF) that describes an angle-resolved of surface is available for characterizing properties a material. A one-shot BRDF imaging system can capture in-plane color mapping light direction extracted from distribution. roughness identification method then proposed here using the system. difference between matt paper and glossy experimentally shown to be detected method. reconstruction axisymmetric micro-object also here. shows it reconstruct aluminium cone with height 37 μm.
