xD Reflect

The Joint Research Project „Multidimensional reflectometry for industry“ aims to validate reliable optical measurements with traceability to the SI-system to describe the overall macroscopic appearances of modern surfaces.

Objects can be identified through visual surface attributes such as colour, gloss, texture, transparency, graininess or sparkle. The compilation of these visual attributes gives
the appearance of the surface. The appearance of a product is important for several industries, e.g. automotive, cosmetics, paper, printing, packaging, coatings, plastics, steel industries, etc. because it is frequently one of the most critical parameters affecting customer choice.
For this reason, since 20 years, a lot of efforts have been conceded by the manufacturers to propose new and sophisticated visual effects, like metallic paintings, goniochromatism, deep matt finishes or sparkle effects for instance.

Metrology in the field of multidimensional reflectometry measurement will be accomplished by artefacts, databases and protocols developed within the project, to be the basis for future international standards.
