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…

Single-Image Geometric-Flow X-Ray Speckle Tracking
David M. Paganin, Helene Labriet, Emmanuel Brun +1
We develop a speckle-tracking method for x-ray phase-contrast imaging, based on the concept of geometric flow. This flow is a conserved current associated with deformation of illum…
