|Abstract:||A method of determining the second-order derivatives of displacement using digital shearing speckle interferometry is presented in this paper. A phase-shifting technique is incorporated and demonstrated to yield good quality fringe patterns that depict either the second-order derivative separately or a combination of first- and second-order derivatives. The optical set-up of this method is similar to that of conventional phase-shifting shearography, thus enjoying a simple and practical configuration. Qualitative comparison shows acceptable agreement of the generated fringe patterns with theoretical results. © 2002 Elsevier Science Ltd. All rights reserved.|
