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

X-ray imaging is a standard tool for the non-destructive inspection of the internal structure of
samples. It finds application in a vast diversity of fields: medicine, biology, many engineering …

Schlieren and shadowgraph techniques are basic and valuable tools in various scientific
and engineering disciplines. They allow us to see the invisible: the optical inhomogeneities …

We demonstrate simultaneous phase and amplitude extraction from a single defocused
image of a homogeneous object. Subject to the assumptions explicitly stated in the …

X-ray tomography is an invaluable tool in biomedical imaging. It can deliver the three-
dimensional internal structure of entire organisms as well as that of single cells, and even …

IN conventional radiography, X-rays which pass through an object along different paths are
differentially absorbed, and the intensity pattern of the emerging beam records the …

X-ray radiographic absorption imaging is an invaluable tool in medical diagnostics and
materials science. For biological tissue samples, polymers or fibre composites, however, the …

Diffraction enhanced imaging is a new x-ray radiographic imaging modality using
monochromatic x-rays from a synchrotron which produces images of thick absorbing objects …

This estimate is then recursively optimized10, 14 using a full description of the nonlinear
image formation process. The approach is based on the Fresnel diffraction approximation …

We demonstrate that interferometric imaging may be replaced by noninterferometric
propagation-based techniques in many experiments. We explore propagation through the …
