About

Berta Bernad is a materials scientist specializing in the optical characterization of advanced coatings, with a particular focus on diffraction pigments and iridescent surfaces. Her research bridges color science, appearance modeling, and industrial application, addressing the challenge of quantifying the complex visual effects produced by these innovative materials. Her most cited work, "Color characterization of coatings with diffraction pigments" (2016, 14 citations), introduced a rigorous methodology for measuring the spectral bidirectional reflectance distribution functions (BRDFs) of coatings containing SpectraFlair diffraction pigments. Using a robot-arm-based goniometer, Bernad captured the full angular variation of light scattering, enabling accurate description of the high iridescence that defines these coatings. This contribution is critical for quality control and design in automotive, cosmetics, and security printing industries, where consistent, predictable appearance is essential. Bernad’s research stands out for its practical impact, providing a foundational framework for characterizing complex goniochromatic materials. Her work has been cited by peers developing advanced appearance models and by engineers optimizing pigment formulations, marking her as a key contributor to the field of optical metrology for functional coatings.
