This paper uses Digital Image Correlation (DIC) technique developed in our laboratory to measure the deformation of solids and structures for multi-scale and multi-field problems. DIC is a non-contact and full-field measurement technique. The advantage of DIC is the simplicity of experiment setup. Recording the images of the deformation of object, DIC has ability to measure displacement and strain fields through self-developed image processing technique. Using high-speed camera for dynamic problem, the issue of sub-micron problem can also be measured by the use of high-resolution microscope. The measurement of deformation in civil engineering and material science are important applications and are presented in the paper. The trajectory analysis of robotic arm, quasi-static deformation of cantilever beam and the deformation of carbon fiber material related to mechanical engineering are also investigated. The results obtained from the DIC method are compared with that obtained by other experimental techniques.
