Laser ultrasonics


With a strong expertise in laser-based ultrasound technologies, Sound & Bright offers a wide range of systems for various applications, from the laboratory to industry.

The Tempo 1D ultra high-frequency (UHF) laser receiver is capable of detecting surface displacements resulting from the propagation of UHF ultrasounds, up to GHz. The system measuring the spatial component normal to the surface of the target tested is used for the characterisation of micro and nano components. The system has become one of the most popular laser receivers worldwide for high-frequency and UHF inspection.

The Tempo 2D multi-component laser receiver is capable of simultaneously measuring two components of the surface displacement, the out-of-plane and the in-plane motions, using a single laser probe and a single collecting optic. The detection of the in-plane component allows efficient detection of shear waves to be achieved, particularly when the direction of ultrasound propagation is normal to the surface of inspection.

The optical set-up of the Tempo 2D is based on the Tempo 1D but with a customised linear array photo-detector, capable of detecting both the in-plane and out-of-plane contributions of the surface displacement. The system is capable of reconstructing the complete ultrasonic field.

The Quartet multi-purpose laser receiver is well suited to a wide range of ultrasonic laboratory and factory applications and is available in visible or infrared versions. Based on the company’s patented multi-channel random quadrature detection technology, the system is designed for remote detection of sub-nanometer displacements. The system was created in order to go beyond surrounding noise during fast inspection.

Founded by experts in optics and NDT, Sound & Bright specialises in the development of innovative NDT instruments. A strong expertise in laser ultrasound has led Sound & Bright to develop sensors for various applications and technologies.
