Digital Image Correlation (DIC) is a non-contact, non-interferometric measurement technique that uses high-resolution machine-vision digital cameras to accurately measure surface deformation in two or three dimensions. This measurement is presented graphically in a number of ways such as a 2D strain map overlaying the test specimen, or a 3D displacement map showing the specimen surface and how it moves throughout the test. 

Early development of this technology began in the mid-1980s in the mechanical engineering department of the University of South Carolina. Since then it has gone on to revolutionize mechanical testing on both the macro and micro scale. 

The applications of DIC are vast, from eyeball pressure testing to earthquake analysis; this adaptable and highly capable system will transform design, validation and testing methods for anything from dental implants to wind turbines.
