Laboratory-based X-ray phase-imaging scanner using Talbot-Lau interferometer for non-destructive testing

Abstract An X-ray Talbot-Lau interferometer scanning setup consisting of three transmission gratings, a laboratory-based X-ray source that emits X-rays vertically, and an image detector on the top has been developed for the application of X-ray phase imaging to moving objects that cannot be tested c...
