Abstract :
Laser shearography is applied to the defects detection of the airplane composite materials with interfacial viscose brushing off and delaminating damage. The form and the theory of laser shearography system are analyzed in this paper. Results show that the damage can be exactly quickly located ignoring the global displacement with the Wollaston prism.
