title: Phase-correlation techniques for quasi real-time measurement of deformations with digital speckle interferometry.
abstract: A new approach of in-plane speckle-displacement analysis by binary phase-correlation evaluation is described. An optical implementation of the method based on digital speckle-pattern interferometry and one-focal-length correlator architecture that uses a liquid-crystal light valve is proposed.
