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 ...

Researchers have discovered brand new interference patterns in twisted two-dimensional tungsten ditelluride lattices. These so-called moir patterns can be tuned to look like periodic spots or even one ...

X-ray diffraction (XRD) is a powerful non-destructive analytical technique used to evaluate crystalline materials and determine their structural properties. As one of the most widely used ...
