Paper Abstract

In this paper, fundamentals of electronic shearography and electronic holography are outlined. Equations for quantitative interpretation of the electronically generated interferograms are discussed and their implementation is presented and illustrated by representative examples. These examples were obtained by operating the shearographic and holographic systems side by side. Responses of the object to static and dynamic loads were recorded using double-exposure and time-average interferograms. Comparison of the electronically generated shearographic and holographic results shows good correlation with each other and also with the theoretical results.
