Optical properties of in situ eye lenses measured with X-ray Talbot interferometry: a novel measure of growth processes. [PDF]
PLoS ONE, 2011 The lens, a major optical component of the eye, has a gradient refractive index, which is required to provide sufficient refractive power and image quality.

Development of x-ray phase tomographic microscope based on Talbot interferometer at BL37XU, SPring-8
AIP Advances, 2020 An x-ray phase tomographic microscope has been developed by optimizing the optical system for 9-keV synchrotron x rays at BL37XU, SPring-8, Japan. The system consists of a full-field x-ray imaging microscope and a Talbot interferometer.

Comparison of Thermal Neutron and Hard X-ray Dark-Field Tomography
Journal of Imaging, 2020 High visibility (0.56) neutron-based multi-modal imaging with a Talbot–Lau interferometer at a wavelength of 1.6 Å is reported. A tomography scan of a strongly absorbing quartz geode sample was performed with both the neutron and an X-ray grating ...

A momentum filter for atomic gas
New Journal of Physics, 2013 We propose and demonstrate a momentum filter for atomic gas-based on a designed Talbot–Lau interferometer. It consists of two identical optical standing-wave pulses separated by a delay equal to odd multiples of the half Talbot time.

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 ...

Phase-Contrast and Dark-Field Imaging
Journal of Imaging, 2018 Very early, in 1896, Wilhelm Conrad Röntgen, the founding father of X-rays, attempted to measure diffraction and refraction by this new kind of radiation, in vain. Only 70 years later, these effects were measured by Ulrich Bonse and Michael Hart who
