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.

Modeling Vibrations of a Tiled Talbot-Lau Interferometer on a Clinical CT [PDF]
IEEE Transactions on Medical Imaging, 2022 X-ray computed tomography (CT) is an invaluable imaging technique for non-invasive medical diagnosis. However, for soft tissue in the human body the difference in attenuation is inherently small. Grating-based X-ray phase-contrast is a relatively novel imaging method which detects additional interaction mechanisms between photons and matter, namely ...
