Measurement of Vibration Mode Structure for Adaptive Vibration Suppression System by Digital Holography

Popis výsledku v původním jazyce

Previously the frequency-shifted digital holographic interferometry (FSDHI) for measurement of vibration amplitudes in range of nanometers was introduced and verified by authors. The method FSDHI addressed some of the drawbacks of the conventional methods and was used mainly for piezoelectric transformer vibration amplitudes and mode structures measurement. The limiting factor for application of this method is the maximal measured value of the vibration amplitude without the risk of ambiguity. The valueis approximately 80nm for the frequency doubled Nd: YAG line. Since FSDHI enables us to precisely measure vibration amplitudes over the whole inspected area with very high lateral resolution, it could also be a very useful tool for measurement of vibration amplitudes and mode structures for research in the field of adaptive suppression systems. Such a measurement would provide a necessary feedback about the system behavior. This was the reason why we put an effort to the modification of
