Paper Abstract

In this work, the measurements done, by way of digital holography, of auto-induced mechanical oscillations assumed by signals of frequency near to the first natural modal of resonance, are reported. Using a high speed digital camera, the study of a rectangular membrane under external excitation of a very low mechanical amplitude level, is done. The optical technique of high temporal and spatial resolution allows the acquisition and processing of data coming from thousands of acquired images with a relation of 5000 frames per second.
