Definition

Non-contact, full-field optical method that quantifies surface displacements and derives strains by matching (correlating) local intensity or speckle patterns between a reference image and one or more deformed images; implementations include 2D (single-camera) and 3D (stereo) configurations, and accuracy depends on imaging geometry, surface texture, correlation algorithm and calibration.
