Scanning Laser Doppler Vibrometer Type

The non-contact measurement methods used in laser-based vibrometers offer some unique advantages compared to using traditional, surface mounted accelerometers. Applications that were previously difficult or even impossible to perform can now be accomplished. This includes measurements on small lightweight, delicate or hot structures, inaccessible parts and measurements in high-voltage or radioactive environments. Furthermore, the frequency range can be quite high.

When using a Scanning Laser Doppler Vibrometer (SLDV), additional benefits are gained. This includes high spatial resolution in the measurement and fast and flexible data acquisition.

The paper itself describes the major features of such Scanning laser Doppler Vibrometer in general, but emphasis will be given during the oral presentation to its benefits in the automotive industry specifically.
