The Joint Research Project “New quantities for the measurement of appearance“ is a collaboration between National Metrology Institutes, partners from Industry and the research Community in Europe.
It aims to advance primary metrology in spectrophotometry. The project will provide new traceable primary references, which will provide new tools for quality control and more realistic solutions for virtual prototyping. This will benefit different industrial sectors e.g. automotive, paper, cosmetic and 3D-printing.
The project will involve defining the new quantities Bidirectional Transmittance Distribution Function (BTDF) and Bidirectional Surface Scattering Reflectance Distribution Function (BSSRDF), and further improving the measurements of Bidirectional Reflectance Distribution Function (BRDF).
