Abstract

This paper reports on the application of phase shifting interferometry to comparative holography. The method here enables the measurement of phase distributions corresponding to the difference in displacements of two nominally identical specimens subjected to similar loading steps. Different aspects of the method are discussed, and experimental results are presented to demonstrate the feasibility and versatility of the technique in flaw detection.
