Abstract

Image processing has been used to analyze TV-holographic fringe patterns of deformation and vibrations. Recent results using such image processing algorithms for deformation and vibration measurements are described. It is shown how these techniques has been used on practical objects such as concrete, high-frequency transducers, and underwater transducers.
