About

Sven Teichert is a leading researcher in optical metrology at the Physikalisch-Technische Bundesanstalt (PTB), Germany’s national metrology institute. His work centers on the precise measurement of visual appearance—specifically goniochromatism (color shift with viewing angle) and sparkle effects—critical for industries like automotive coatings, cosmetics, and packaging. Teichert’s major contribution is the development of ARGon3, the “3D appearance robot-based gonioreflectometer,” a pioneering facility that enables high-accuracy, multidimensional measurement of surface reflectance. This system, detailed in his most-cited paper (28 citations), set a new standard for capturing complex optical properties. He further advanced the field by designing a novel LED-based radiation source for diffuse reflectometry, improving spectral radiance factor measurements and polarization studies. Teichert’s work bridges fundamental metrology and industrial application, providing the tools needed to quantify and control the visual quality of effect pigments. His achievements at PTB underscore his role in establishing traceable, reproducible standards for appearance measurement, directly supporting quality assurance in high-tech manufacturing.
