Abstract

Electronic speckle pattern interferometry (ESPI) utilizing a phase-modulation of the object beam and a continuous reference-updating technique is proposed to provide noise reduction in optical NDE methods. Unlike conventional ESPI techniques, this method uses phase modulation between successively subtracted additive speckle interference images. The ability of this technique to work in a turbulent environment is demonstrated, and application to detection of structural defects in adhesively bonded structures, a problem of interest to the NDE community, is shown.
