Paper Abstract

This paper presents the application of a high-speed phase- shifting speckle interferometer to the detection of sub- surface delamination defects in carbon fiber specimens. Speckle interferograms are continuously recorded by a CCD camera operating at 1 kHz with temporal phase shifting carried out by a Pockels cell running at the same frequency rate. Temporal phase unwrapping through sequences of more than 1000 frames allows the determination of time-varying absolute displacement maps.
