When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

Phase-contrast x-ray imaging (PCI) is an innovative method that is sensitive to the refraction
of the x-rays in matter. PCI is particularly adapted to visualize weakly absorbing details like …

X-ray sources are developing rapidly and their coherent output is growing correspondingly.
The increased coherent flux from modern X-ray sources is being matched with an …

In-line phase-contrast X-ray imaging provides images where both absorption and refraction
contribute. For quantitative analysis of these images, the phase needs to be retrieved …

X-ray phase-contrast imaging and tomography make use of the refraction of X-rays by the
sample in image formation. This provides considerable additional information in the image …

Absorption-contrast x-ray imaging serves to visualize the variation in x-ray attenuation within
the volume of a given sample, whereas phase contrast allows one to visualize variations in x …

When a very-low-absorbing sample is scanned at an x-ray computed tomography setup with
a microfocus x-ray tube and a high-resolution detector, the obtained projection images …

Phase retrieval is a technique for extracting quantitative phase information from X-ray
propagation-based phase-contrast tomography (PPCT). In this paper, the performance of …

In this report we clarify two aspects for in‐line phase‐sensitive x‐ray imaging, which
includes phase‐contrast imaging and phase imaging. First, we point out that there is …

A method is presented for quantitative phase-contrast tomography using unfiltered radiation
from a small polychromatic source. The three-dimensional distribution of complex refractive …
