TEMPO Laser Ultrasound

TEMPO Laser Ultrasound

This product facilitates measurement of sub-picometre in-plane and out-of-plane displacement at high frequency (up to 1GHz) on any surface type without contact.
Technology From: Bossa Nova Technologies

TEMPO Laser Ultrasound

TEMPO laser ultrasound has been designed for precise laboratory experiment. It can measure in-plane and out-of-plane surface displacement with ultra-sensitivity (Detection of sub-nm displacement), high frequency (up to 1GHz) and excellent spatial resolution (down to 10 micrometre diameter spot on the sample).

This product facilitates measurement of sub-picometre in-plane and out-of-plane displacement at high frequency (up to 1 GHz) on any surface type without contact. Based on photorefractive two-wave mixing, TEMPO works at optimum performances with multi-speckled beam. TEMPO large aperture (∼50mm) collects much more optical power on diffusing surfaces than a classical interferometer, which directly translates into higher sensitivity and signal to noise ratio. Output delivers a time signal directly proportional to the surface displacement of the sample.

Designed for point-and-shoot operation, TEMPO is easy to operate (calibrated output, focus controlled by usb connection, internal photodiode for trigger, etc.) and can be coupled to a 2D scanner (X-Y or angular) for full-field analysis.

TEMPO is used in numerous Universities and private R&D laboratories for materials research and wave propagation studies.

Key Features

QUARTET Laser Ultrasound

QUARTET Laser Ultrasound

QUARTET laser ultrasound has been developed for industrial applications.
Technology From: Bossa Nova Technologies

QUARTET Laser Ultrasound

QUARTET laser ultrasound has been developed for industrial applications. Rugged, compact and insensitive to external perturbation, QUARTET allows the acquisition of ultrasonic signal in difficult industrial environment (On-line measurement on hot moving sample for example).

Rugged, compact and cost-effective, QUARTET has been developed for non-destructive testing and laser ultrasound in industrial environment. Based on multi-channel random quadrature detection technology, it is designed for remote detection of sub-nanometre displacements. No path stabilisation is required. The stability of the interferometer is based on the multi-channel, parallel demodulation that is done electronically.

Coupled to a small fibre head that delivers the probe beam and collects the signal beam, QUARTET is adapted to the versatile and demanding industrial applications where testing on moving, hot sample is often required. Designed for point-and-shoot operation, it is easy to use and can be coupled to a 2D scanner for full-field analysis.
