To reduce costs and facilitate automation of joining processes, adhesive bonding has gained popularity as a replacement for conventional mechanical fastener, especially for bonding parts made of ...

The same as the traditional optical interference technique, shearography obtains the object deformation information by obtaining the phase, and the measured object is often dynamic in practical ...

Shearography and Digital Speckle Pattern Interferometry (DSPI) are advanced optical techniques that have emerged as critical tools in non-destructive testing (NDT). Both methods utilise coherent laser ...

Laser shearography as a nondestructive testing (NDT) method has been used in a production environment for composite structures for two decades and on a variety of aircraft, including the F-22 stealth ...
