Paper Abstract

The capability to visualize, at a single moment, the full surface, or large areas, of engineering components has provided a strong impetus to the development and application of interferometric holography as a metrological tool. At the United Technologies Research Center, its adaptation to the nondestructive evaluation and analysis of structures has continued to expand. As examples, the practical implementation of interfero-metric holography for the optical analysis of rotating objects has recently been demonstrated, and a new swept frequency acoustic stressing technique for HNDT is under development. Both of the above, which utilize pulsed laser illumination, are reviewed herein, together with additional holographic test work conducted at the operating divisions of United Technologies Corporation, to demonstrate the tolerance of interferometric holography to levels of ambient illumination and vibration well above those sometimes felt to restrict its practi-cal application in industrial facilities.
