Abstract

A comparative time-averaged TV holographic technique that allows fringe compensation is presented. The technique employs two identical objects, the test and the master, that are subjected to sinusoidal vibration to detect the difference in either out-of-plane vibration amplitude or phase distributions. In addition, the present optical configuration offers simultaneous visualization of vibration amplitudes of the test object. Detailed theoretical and experimental results are presented.
