Abstract: We used the phase-stepping shearography technique to detect blind holes of various sizes and depths in a Plexiglas (PMMA or polymethyl methacrylate) plastic block. The block was strongly heated (raising the temperature by about 80C)… read more here.

Abstract: BACKGROUND X-ray grating interferometry normally requires multiple steps and exposures, causing a prolonged imaging time. There is motivation to use less steps to reduce scanning time and complexity, while keeping fidelity of the retrieved signals.… read more here.
