Founded by experts in optics and non-destructive testing, Sound & Bright is specialized in the development of innovative laser-ultrasound testing instruments. Our popular Quartet multi-purpose laser receiver is suited for a wide range of acoustic and ultrasonic applications from the laboratory to the factory and available in the visible or infrared. Based on our patented multi-channel random quadrature detection technology, the system is designed for remote detection of sub-nanometer displacements. The system offers high sensitivity, requires low to no maintenance, can be fitted with a variety of laser wavelengths, and is capable of rapid scans and measurements. For simultaneous multi-component measurements or ultra-precise testing see our Tempo 2D and 1D respectively. We continually explore the application of innovative technologies through government or private R&D contracts to enhance the performance of our instruments and develop new inspection techniques.
