Abstract

A holographic stroboscopic method is useful especially for large vibration amplitude analyses but a vibration mode cannot be judged by this method. In this paper it is shown that a vibration mode can be analyzed by using two stroboscopic holographic interferograms synchronized with a slight difference. Experimental results of a cantilever vibration measurement show us the proposed method is useful.
