Flexible X-ray Talbot-Lau interferometer and its theory

Optics Express
X-ray Talbot-Lau interferometer, offering multi-contrast for the imaged objects, has shown powerful capacity in imaging biological soft tissues, low density materials, etc. However, the length of the system is constant, which limits its applications. Here, we establish a new X-ray Talbot-Lau interferometer theory to achieve a flexible phase contrast ...

Laboratory-based X-ray phase-imaging scanner using Talbot-Lau interferometer for non-destructive testing [PDF]

Scientific Reports, 2017
An X-ray Talbot-Lau interferometer scanning setup consisting of three transmission gratings, a laboratory-based X-ray source that emits X-rays vertically, and an image detector on the top has been developed for the application of X-ray phase imaging to ...

Towards virtual histology with X-ray grating interferometry [PDF]

Scientific Reports, 2023
Breast cancer is the most common type of cancer worldwide. Diagnosing breast cancer relies on clinical examination, imaging and biopsy. A core-needle biopsy enables a morphological and biochemical characterization of the cancer and is considered the gold

A study of optical vortices inside the Talbot interferometer [PDF]

, 2015
The optical Talbot interferometer has been used to explore the topological charges of optical vortices. We recorded the self-imaging of a diffraction grating in the near-field regime with the optical vortex of several topological charges. Our twisted light was generated by a spatial light modulator (SLM).

History of the steel industry in the Port Talbot Area 1900-1988 [PDF]

, 2011
This thesis examines the history of steelmaking at Port Talbot in South Wales from the start of modern steelmaking in 1902 to 1988. Although the British steel industry has been studied at national level, few studies have looked at company level and ...

Beam-hardening correction in clinical x-ray dark-field chest radiography using deep-learning-based bone segmentation. [PDF]

Med Phys
Abstract Background Dark‐field radiography is a novel x‐ray imaging modality that provides complementary diagnostic information by visualising microstructural properties of lung tissue. Implemented via a Talbot–Lau interferometer integrated into a conventional x‐ray system, it permits simultaneous acquisition of perfectly registered attenuation and ...

Look-up table correction for beam hardening-induced signal of clinical dark-field chest radiographs. [PDF]

Med Phys
Abstract Background The microstructure of material at a μm$\,\umu\mathrm{m}$ length scale leads to ultra‐small‐angle scattering of X‐rays, which typically occurs, e.g., for lung tissue or some plastic foams. When using an interferometer, this effect alters the visibility of the fringe pattern, which can be detected and resolved by the detector.

Automated alignment of XFEL nanofocusing mirrors via wavefront optimization. [PDF]

J Synchrotron Radiat
An automated alignment system for nanofocusing Kirkpatrick–Baez mirrors has been developed at SACLA. A wavefront optimization technique routinely provides nanofocused XFEL beams.An automated alignment procedure, based on wavefront measurement with a single‐grating interferometer, has been developed for precise tuning of Kirkpatrick–Baez nanofocusing ...
