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 ...
Digital shearography is an optical interferometric technique that measures surface strain by comparing two speckle patterns displaced laterally relative to one another. By analysing the phase ...
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 ...
