Sound waves can reveal surface properties. Parameters such as surface or coating quality of components can be analyzed nondestructively using lasers and sensors. In research and some industrial laboratories, this laser-induced surface wave spectroscopy has already become an established measurement technology. With “LAwave”, the Fraunhofer Institute for Material and Beam Technology IWS in Dresden will present the second generation of a user-friendly measuring device at the International trade fair for quality assurance “Control” in April 2024, which will pave the way into industrial practice.
“This technology enables us to examine coatings and surfaces non-destructively, quickly, and very accurately,” explains project odbbahh Vt.
