TEMPO

Thanks to Bossa Nova Technologies innovative approach, it is now possible to measure sub-picometer displacement/vibrations at high frequency on any surface type without contact.
Based on photorefractive two-wave mixing, TEMPO works at optimum performances even with a multi-speckle beam. TEMPO large aperture collects much more optical power on diffusing surfaces than a classical interferometer, which directly translates into higher sensitivity and signal to noise ratio. TEMPO operates with an internal CW doubled Nd:YAG laser, at 532 nm (green). The laser power is adapted to the the user application and needs. TEMPO output delivers a time signal proportionnal to the surface displacement of the sample.
The unique features of TEMPO make it easy to use as a "point and shoot" system.		Optical collection of a multi-speckle signal


The standard laser power is 200 mW.

TEMPO is mainly used in R&D laboratory for materials research and wave propagation studies. Coupled with a scanner, TEMPO can proceed to full-field analysis.
