Universal mask for hard X rays
David Ceddia, Alaleh Aminzadeh, Philip K. Cook +3
The penetrating power of X rays underpins important applications such as medical radiography. However, this same attribute makes it challenging to achieve flexible on-demand patter…
Optimizing illumination patterns for classical ghost imaging
Andrew M. Kingston, Lindon Roberts, Alaleh Aminzadeh +3
Classical ghost imaging is a new paradigm in imaging where the image of an object is not measured directly with a pixelated detector. Rather, the object is subject to a set of illu…
Ghost projection. II. Beam shaping using realistic spatially-random masks
David Ceddia, Andrew M. Kingston, Daniele Pelliccia +2
Spatial light modulation is important for many scientific and industrial applications. The spatial light modulator and optical data projector both rely on precisely configurable op…
X-ray phase-contrast imaging: a broad overview of some fundamentals
David M. Paganin, Daniele Pelliccia
We outline some basics of imaging using both fully-coherent and partially-coherent X-ray beams, with an emphasis on phase-contrast imaging. We open with some of the basic notions o…
On the Inherent Dose-Reduction Potential of Classical Ghost Imaging
Andrew M. Kingston, Wilfred K. Fullagar, Glenn R. Myers +3
Classical ghost imaging is a computational imaging technique that employs patterned illumination. It is very similar in concept to the single-pixel camera in that an image may be r…
Boosting spatial resolution by incorporating periodic boundary conditions into single-distance hard-x-ray phase retrieval
David M. Paganin, Vincent Favre-Nicolin, Alessandro Mirone +6
A simple coherent-imaging method due to Paganin et al. is widely employed for phase-amplitude reconstruction of samples using a single paraxial x-ray propagation-based phase-contra…
