Non-binary phase gratings for x-ray imaging with a compact Talbot interferometer

, 2014
X-ray imaging using a Talbot-Lau interferometer, consisting of three binary gratings, is a well-established approach to acquire x-ray phase-contrast and dark-field images with a polychromatic source.

Critical correlations in an ultra-cold Bose gas revealed by means of a temporal Talbot-Lau interferometer

, 2013
The transition from a thermal cloud to a Bose-Einstein condensate (BEC) in an interacting ultra-cold Bose gas is a prototype in a universality class of diverse phase transitions.

Fabrication and Characterization of a Plasmonic Ellipsoidal Nanohole Array With Chiral Response

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
An intrinsically chiral plasmonic platform is realized using ellipsoidal nanohole arrays where mirror symmetry is broken by a precise 18° structural rotation through a scalable displacement Talbot lithography approach. This architecture yields a significant circular dichroism signal of 20%–30% at normal incidence, offering a robust and high‐performance

Fabrication of Gratings for an X-ray Talbot Interferometer

2006 IEEE International Symposium on MicroNanoMechanical and Human Science, 2006
X-ray based imaging measurement has found applications in fields such as medical diagnosis and nondestructive inspection, having become one of essential technologies. However, its low sensitivity to biologically soft tissues limits scope of applications. Several methods have been developed for X-ray phase imaging.

Outdoor Stability of 518 cm2 Active Area Screen‐Printed Mesoscopic Carbon‐Based Perovskite Solar Modules Over 12 Months

Advanced Materials Technologies, Volume 11, Issue 2, 22 January 2026.
Mesoscopic carbon‐based perovskite solar cells (C‐PSCs) offer a pathway to stable, scalable, low‐cost photovoltaics via commercially mature fabrication methods. While their potential lifespan has been demonstrated under standardized conditions, few studies examine the behavior of large‐area modules exposed to real‐world environments. Here, 12 months of

Asymmetric Talbot-Lau interferometry for inertial sensing [PDF]

, 2016
We study in detail a peculiar configuration of the Talbot-Lau matter wave interferometer, characterized by unequal distances between the two diffraction gratings and the observation plane.

Deformable image registration of dark‐field chest radiographs for functional lung assessment

Medical Physics, Volume 52, Issue 8, August 2025.
Abstract Background Dark‐field radiography of the human chest has been demonstrated to have promising potential for the analysis of the lung microstructure and the diagnosis of respiratory diseases. However, most previous studies of dark‐field chest radiographs evaluated the lung signal only in the inspiratory breathing state.

Demonstrating grating-based phase-contrast imaging of laser-driven shock waves

Matter and Radiation at Extremes
Single-shot X-ray phase-contrast imaging is used to take high-resolution images of laser-driven strong shock waves. Employing a two-grating Talbot interferometer, we successfully acquire standard absorption, differential phase-contrast, and dark-field ...
