Vibration
 |
We propose methods for measuring vibration based on laser techniques.
The laser vibrometer is a simple tool that can overcome any instrumentation such as accelerometers bending, wiring, etc ....
The techniques of speckle interferometry provide information field. Data they are particularly efficient in modal analysis and as an investigative tool in cases of complex vibrational behavior.
Vibration analysis
HOLO3 has test rigs dedicated modal analysis that allows a rapid and accurate determination of the eigenmodes of a part. 
Pulsed TV-Holography
The pulsed TV-holography technique is the best method for the measurement of vibration amplitude map, either in laboratory or on site in harsh conditions. It can measure up to one square meter surfaces.
Laser vibrometry
Non-contact measurement of displacement and / or speed of a point of an object subjected to vibration.
