Selected Measurements
real-time vibrometry measurements
Vibrometry measurements as performed on a piezoelectric ceramic,
measured with a FPS sensor. Stunningly, vibration amplitudes of few
picometers can be detected even at low frequency.
Ultra-wide frequency range vibrometry
The FPS sensor is not only a very capable real-time displacement sensor
but it also serves the user as a powerful vibrometer. With its built-in
fast-Fourier algorithm (FFT), the FPS series directly detects the distri-
bution of vibrational modes/amplitudes in frequency space. Frequency
and phase information of resonance peaks can be live-viewed on the
PC-based FPS application software. The data above demonstrate the
suitability of the FPS sensor for this type of application. In this specific
case, the low-frequency noise behaviour of the FPS sens
