A digital measurement system based on laser displacement sensor for piezoelectric ceramic discs vibration characterization
Original language description
tThis study describes the innovative design of a digital measurement system based on a laser displacementsensor (LDS) as a vibrometer which is capable to measure a dynamic displacement response dependenceon a stimulated vibration. The frequency response of a piezoelectric ceramic disc is obtained by processingthe input/output signals obtained from the function generator and digital oscilloscope (digitizer) cardsdriven by a personal computer. Resonant frequencies of vibration are achieved utilizing the swept-sinesignal excitation following the peak values in the signal response measured by LDS. The analogue signalfrom LDS controller represents directly a mechanical vibration of a piezoceramic disc. The test measure-ment results indicate that the system can distinguish resonance frequencies of piezoelectric ceramic discsup to 40 kHz with the resolution 1 Hz. Piezoelectric coefficient d33and its linearity along the excited volt-age amplitudes have been calculated by the applied methods as a demonstration of a successful systemconcept. The results achieved are in compliance with the reference value declared by the manufacturer of the piezoceramic disc.
