Abstract

Abstract

The behavior of the digital shearing speckle fringe formation was discussed systematically with the theory of statistical optics. Quantitative NDT of bimaterial interface defects was achieved by using the phase-shifting shearing speckle interferometry system with non-contact, high accuracy, full-field and real-time.
