Project: Bidirectional reflectance definitions

Acronym	16NRM08 BiRD (Reference Number: 16NRM08)
Duration	01/05/2017 - 30/04/2020
Project Topic	Products from cars, to cosmetics, to paper depend upon sophisticated visual effects - colour, gloss, transparency, texture - for commercial success. Considerable R&D goes into creating metallic paints, pigments, finishes, sparkle and grainy effects. Commercial devices using Bidirectional Reflectance Distribution Function (BRDF), a reflection technique suitable for measuring sophisticated visual effects, have recently been developed. Primary references and calibration artefacts for these have been established at NMIs, but there remains a lack of BRDF standards.The project will use results from EMRP project IND52 xDReflect to carry out BRDF measurements on different visual effects and independently validate them, and use these measurements to propose standards and guidance, as well as agreeing formats for measurement data. It will make recommendations for the characterization of surface gloss, sparkle and graininess effects and agree new approaches for measuring these. Standardised approaches to BRDF will help manufacturers produce a new generation of instruments, giving many industries, including automotive and cosmetics, better control of product appearance and higher customer satisfaction
