A Kapitza–Dirac–Talbot–Lau interferometer for highly polarizable molecules [PDF]
Nature Physics, 2007 Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clusters and hot molecules. Coherence experiments with complex objects are of interest for exploring the transition to classical physics, for measuring molecular properties and ...

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 ...

Ultrafast sub-nanometer matter-wave temporal Talbot effect
New Journal of Physics, 2021 The coherent manipulation of the electron wavefunction at the atomic spatial and temporal scales is the fundamental breakthrough underlying far-reaching ultrafast phenomena as high-order harmonic radiation and attosecond pulse generation.

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.

Discrimination analysis of breast calcifications using x‐ray dark‐field radiography
Medical Physics, Volume 47, Issue 4, Page 1813-1826, April 2020., 2020 Background X‐ray dark‐field radiography could enhance mammography by providing more information on imaged tissue and microcalcifications. The dark field signal is a measure of small angle scattering and can thus provide additional information on the imaged materials.

Electron interferometry with nano-gratings [PDF]
, 2006 We present an electron interferometer based on near-field diffraction from two nanostructure gratings. Lau fringes are observed with an imaging detector, and revivals in the fringe visibility occur as the separation between gratings is increased from 0 ...

Advancing research and education with simple setup Talbot-Lau-Interferometers
e-Journal of Nondestructive Testing, 2023 Grating based interferometry is a widely established technique used for various applications in X-ray imaging, from materials science [1,2] to medical diagnosis [3,4]. Talbot-Lau-Interferometers are especially promising for laboratory-based setups. By introducing a source grating into the optical setup, requirements on the spatial coherence of the ...
