From classical xenon fringes to hydrogen interferometry
New Journal of Physics, 2020 A setup with three equally spaced transmission gratings can be described as a moiré deflectometer in the classical regime and as a Talbot–Lau interferometer in the quantum regime.

Two-grating Talbot bands spectral-domain interferometer [PDF]
Optics Letters, 2015 A configuration for Talbot bands is presented in which two tilted gratings replace the splitter normally used for recombining the signals from the two interferometer arms. The two optical beams from the interferometer are launched by two fiber leads tightly brought together in the front focal plane of a collimating lens.

Matter-wave interference of a native polypeptide
Nature Communications, 2020 Matter-wave interferometry of complex molecules is challenging due to difficulties in preparing and detecting molecular beams. Here the authors demonstrate quantum behavior of a polypeptide using matter-wave interference in an all-optical time-domain ...

Modeling Vibrations of a Tiled Talbot-Lau Interferometer on a Clinical CT
IEEE Transactions on Medical Imaging, 2023 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 ...
