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…
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…
Ghost Projection
David Ceddia, David M. Paganin
Ghost imaging is a developing imaging technique that employs random masks to image a sample. Ghost projection utilizes ghost-imaging concepts to perform the complementary procedure…
On Random-Matrix Bases, Ghost Imaging and X-ray Phase Contrast Computational Ghost Imaging
David Ceddia, David M. Paganin
A theory of random-matrix bases is presented, including expressions for orthogonality, completeness and the random-matrix synthesis of arbitrary matrices. This is applied to ghost…
