摘要
Recently there has been considerable research activity in the development of digital shearography for nondestructive testing (NDT) in production/field environments. The research has shown that digital shearography has great potential in identifying discontinuities in objects and especially in the detection of delaminations in composite materials such as honeycomb structures. This paper is a review of the state of the art of digital shearography for NDT. Recent developments of digital shearography and its potentials and limitations for NDT will be demonstrated by examples of nondestructive testing for different materials.
