On imaging capabilities of the Imaging and Medical beamline at the Australian Synchrotron
T. E. Gureyev, K. M. Pavlov, C. J. Hall +6
Several propagation-based and analyser-based X-ray phase-contrast imaging experiments with over 100 m between the imaged objects and the detector were carried out at the Imaging an…

Laser-induced phase shift of swift electrons
Christian Dwyer, David M. Paganin
We revisit the calculation of the phase shift experienced by swift electrons on passing through the electromagnetic field of a laser. Such phase shifts are now utilized in the form…

Generalized Zernike Phase-Contrast Imaging
Christian Dwyer, David M. Paganin
Zernike phase-contrast imaging is unique among imaging techniques in that it enables the upper limit of Fisher information allowed by quantum mechanics. Here we show that, in a dep…
