A Wigner Function Approach to Coherence in a Talbot-Lau Interferometer [PDF]
Atoms, 2016 Using a thermal gas, we model the signal of a trapped interferometer. This interferometer uses two short laser pulses, separated by time T, which act as a phase grating for the matter waves.

Parabolic gratings enhance the X-ray sensitivity of Talbot interferograms [PDF]
Scientific Reports, 2023 In grating-based X-ray Talbot interferometry, the wave nature of X-ray radiation is exploited to generate phase contrast images of objects that do not generate sufficient contrast in conventional X-ray imaging relying on X-ray absorption.
