Unparalleled sensitivity

At Sound & Bright we believe your endeavor deserves the highest non-destructive testing sensitivity available. We are committed to providing robust systems that do not compromise on performance.

An unwavering commitment to innovation

Sound & Bright’s proprietary technologies set our systems apart. Originating from research and development grants from NASA and the National Science Foundation, these innovations have been continuously refined to stay on the cutting edge.


Sound & Bright specializes in state-of-the-art laser-based ultrasound receivers for non-destructive testing R&D. Our instruments offer unparalleled sensitivity and noise reduction, making them ideal for applications ranging from laboratory research to industrial use. Developed with support from NASA and the National Science Foundation (NSF), our technologies are continuously updated to meet our customers’ high standards and innovation goals. Based in Inglewood, California, we build and customize our instruments to order.


The Quartet

Hi-bandwidth receiver for industrial NDT solutions

Powered by our patented Multi-Channel Random Quadrature technology, the Quartet features two detector arrays, providing a bandwidth of up to 80 MHz. It offers high sensitivity, requires minimal to no maintenance, supports various laser wavelengths, and enables rapid scans and measurements.

The Modulo Uno

Streamlined MCRQ for low laser power

The Modulo Uno features a streamlined version our patented Multi-Channel Random Quadrature technology, offering a bandwidth of up to 20 MHz. Designed to maintain sensitivity with lower probe beam power than its larger counterpart, the Quartet, the Modulo Uno is both cost-effective and ideal for biomedical scanning and transducer characterization. It also includes a digital output for ease of use.

The Tempo 2D

Multi-component receiver

The Tempo 2D simultaneously measures two components of surface displacement—out-of-plane and in-plane motions—using a single laser probe and a single collecting optic. This capability enables efficient detection of shear waves, especially when the direction of ultrasound propagation is normal to the inspection surface.

The Tempo 1D

Ultra-high frequency receiver

The Tempo 1D detects surface displacements resulting from UHF ultrasound propagation, up to GHz frequencies. By measuring the spatial component along the probe beam direction, this system is ideal for characterizing micro and nano components.
