Abstract
Recently, there are considerable research activities in the development of optical methods for nondestructive testing in production/field environments, because of the full-field and noncontacting nature of these methods. Among the various optical methods such as thermography, holography, moire and ESPI etc., shearography appears to be more practical and it is rapidly gaining acceptance by industry. This paper reviews the state-of-the-art of shearography.
