Sharp images from diffuse beams: factorisation of the discrete delta function
I. D. Svalbe, D. M. Paganin, T. C. Petersen
Discrete delta functions define the limits of attainable spatial resolution for all imaging systems. Here we construct broad, multi-dimensional discrete functions that replicate cl…
Neutron Ghost Imaging
Andrew M. Kingston, Glenn R. Myers, Daniele Pelliccia +4
Ghost imaging is demonstrated using a poly-energetic reactor source of thermal neutrons. The method presented enables position resolution to be incorporated, into a variety of neut…
Spatial resolution, noise and information in the computational-imaging era
David M. Paganin, Alexander Kozlov, Timur E. Gureyev
Imaging is an important means by which information is gathered regarding the physical world. Spatial resolution and signal-to-noise ratio are underpinning concepts. There is a pauc…
Single-shot x-ray speckle-based imaging of a single-material object
Konstantin M. Pavlov, Heyang, Li +4
We develop a means for speckle-based phase imaging of the projected thickness of a single-material object, under the assumption of illumination by spatially random time-independent…
One mask to rule them all: Writing arbitrary distributions of radiant exposure by scanning a single illuminated spatially-random screen
David M. Paganin
Arbitrary distributions of radiant exposure may be written by transversely scanning a single known spatially-random screen that is normally illuminated by spatially but not necessa…
Speckled cross-spectral densities and their associated correlation singularities for a modern source of partially coherent x rays
David M. Paganin, Manuel Sanchez del Rio
We consider a realistic model for calculating the cross-spectral density of partially coherent beams from an x-ray undulator in a modern storage ring. This two-point coherence func…
