A facility for measuring the BSSRDF

14th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2021), June 21 - 24, 2021, Virtual OnlyThis work presents a facility for measuring the Bidirectional Scattering-Surface Reflectance Distribution Function (BSSRDF), a function that describes the scattering of the light in translucent materials. This facility targets an expanded uncertainty of 5 %. The BSSRDF of twelve homogeneous and translucent samples has been measured to test the system and some results are represented here.This work was written within the EMPIR 16NRM08 Project “New quantities for the measurement of appearance” (BxDiff).
