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
