Abstract
We have for some years been working on increasing the application range of electronic speckle pattern interferometry - ESPI - especially for vibration analysis. By introducing a vibrating mirror in the reference path we obtain phasemodulating effects, which have greatly increased the amplitude measuring range from originally below one decade to more than six decades [1–2], We have also used phasemodulation to separate the amplitude - and phasedistribution across vibrating surfaces [3], - a procedure which is most valuable if compound modes are to be analyzed.
