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 …

For quantitative phase imaging (QPI) based on transport-of-intensity equation (TIE), partially
coherent illumination provides speckle-free imaging, compatibility with brightfield …

Digital holography is an emerging field of new paradigm in general imaging applications.
We present a review of a subset of the research and development activities in digital …

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 …

Digital holography is one of the most widely used label-free microscopy techniques in
biomedical imaging. Recovery of the missing phase information on a hologram is an …

This paper introduces the capabilities and availability of a customizable scientific software
package called Livermore Tomography Tools (LTT) built for computed tomography (CT) …

We propose an alternative method for solving the Transport of Intensity equation (TIE) from a
stack of through–focus intensity images taken by a microscope or lensless imager. Our …

A well‐known problem in x‐ray microcomputed tomography is low sensitivity. Phase contrast
imaging offers an increase of sensitivity of up to a factor of in the hard x‐ray region, which …

We report the implementation of a method which can yield the 3D distribution of the phase
(refractive index) of a weakly absorbing object from a single tomographic data set. In order to …
