Digital image correlation is a non-contact, optical technique used to analyze the deformation or motion of objects through the comparison of digital images. It is commonly used in materials testing, biomechanics, civil engineering, and other fields to measure strain and displacement in structures or materials. The technique involves capturing images of an object before and after deformation, then using software to track and analyze the movement of specific points or patterns on the object's surface. By correlating the images, researchers can accurately determine the amount of deformation and strain experienced by the object. Digital image correlation provides a precise and efficient method for measuring deformation, strain, and motion in a wide variety of applications.
