XARION Laser Acoustics GmbH

Non-destructive testing — the ability to verify the integrity of a material or structure without damaging it — is a fundamental activity in sectors including aerospace, automotive, medical, and industrial manufacturing. Traditional acoustic sensors, based on piezoelectric elements, require physical contact with the piece being examined, limiting possible applications and complicating the automation of quality control processes. XARION Laser Acoustics GmbH has developed the world's first laser-based acoustic sensor, eliminating the need for physical contact. The underlying technological principle is optical interferometry: the sensor measures acoustic pressure variations through a laser beam, with no physical element that needs to touch the surface of the material being analyzed. This opens up possibilities that conventional sensors cannot cover: inspection of high-temperature surfaces, complex geometries, delicate materials, or environments where physical contact is impossible or undesirable. The main clients are industrial companies, R&D laboratories, medical imaging operators, and non-destructive testing professionals who use acoustic sensors for measurement, monitoring, and inspection. The B2B model with customized solutions reflects the specialized nature of the product: each application has its own requirements in terms of frequency, sensitivity, and geometry. In a market where component quality and reliability are critical and the automation of control processes is accelerating, XARION offers a tool that extends the boundaries of what can be measured without contact.
