Clarification on Generalized Lau condition for X-ray interferometers based on dual phase gratings
Aimin Yan, Xizeng Wu, Hong Liu
To implement dual phase grating x-ray interferometry with x-ray tubes, one needs to incorporate an absorbing source grating. In order to attain good fringe visibility, the period o…
