Paper Abstract

In this paper a new technology for measuring the dynamic behaviour of structures using the stroboscopic laser speckle interferometry is introduced. A good quality of whole-field speckle fringe patterns and Young's fringe patterns can be obtained when this method is used. Moreover, the methods of identifying the phase information of the vibratory structure and choosing the width of He-Ne laser pulses are discussed. Lastly, it presents the experimental results of comparing the stroboscopic laser speckle interferometry with the time-average speckle interferometry.
