Shorter measuring times and greater productivity in laser vibometry

LinkedIn +

Polytec is now offering its PSV-500 and PSV-500-3D series vibrometers with the Xtra option, which greatly increases optical sensitivity.

The Xtra concept is based on an infrared laser that produces more power without sacrificing on eye safety. In addition, more of the infrared light is reflected from the surface. This provides a signal that is at least eight times stronger than that produced using the basic model, which is far more resistant to noise as a result.

The signal-to-noise ratio is improved and resonance frequencies in the fast Fourier transform spectrum become even more clearly visible. This results in more precise data analysis and FE model validation – with shorter measuring times too, as the number of averages that are needed drops significantly.

Also, there is no longer any need to treat surfaces or to reposition the instrument from one scan area to another due to the greater measuring distance, saving time and effort. Users can therefore carry out many more measurements per day, while complex product developments can be turned into reality more efficiently.
