Vibration
 |
We propose vibration measurement processes based on laser techniques.
The laser vibrometer is a simple tool that dispenses with the need for instrumentation and processes like the bonding of accelerometers, wring, etc...
Speckle interferometry techniques supply full-field information. It is particularly efficient for modal analysis and as an investigatory tool in the cases of complex vibration behavior situations.
Vibration analysis
HOLO 3 has a TV holography bench that alloows fasf and precise determination of the natural modes of a part. 
TV-Holo pulsed
For surfaces larger than a square meter, the large deformation amplitudes or measurements on site, pulsed laser interferometric techniques are to be preferred. The advantage of the technique is to allow the measurements to be made on site under difficult conditions.
Laser vibrometry
Contactless measurement of displacement and/or speed of the point of an object according to the sensitivity vector.
