Abstract
Digital image correlation (DIC) methods initially were developed in the early 1980s to simplify basic in-plane laboratory experiments, modified in the 1990s to obtain full three-dimensional surface displacements and shape measurements on curved or planar specimens and then extended to interior measurements at the end of the last millennium. The enclosed article provides a brief description of the various digital image correlation methods, followed by a personal perspective regarding recent and future developments utilizing DIC measurements.
