- W2514939812 abstract "Electronic speckle pattern interferometry (ESPI) and digital shearography have been shown to be of great value for the nondestructive testing of the integrity of materials and manufactured components. The NDT Laboratory in the Department of Mechanical Engineering at the University of Cape Town has an active research and development group focused on the various applications of ESPI and digital shearography. This work culminated in the development of portable prototype testing systems based on digital shearography and ESPI. These portable systems generate intensity based fringe patterns. By introducing a known phase shift into the speckle pattern during the image recording process, displacement fringe patterns, based on the change in phase of the laser light, can be generated. These fringe patterns differ in that they reveal distinct 2it discontinuities and are thus suited for automated testing techniques and for object surface displacement mapping techniques. This paper reports on the progress made in implementing phase stepped ESPI and digital shearography. The techniques are described and applied to selected anomalous composite samples. The findings are presented and comparison is drawn between the results obtained, both from phase stepping and conventional intensity based optical interference techniques. The possibility of applying phase stepping techniques to portable testing systems is also discussed." @default.
