Object Initialization For Ptychographic Scans With Reduced Overlap
Felix Wittwer, Peter Modregger
X-ray ptychography utilizes overlapping illuminations to reconstruct the object's phase and absorption signal with spatial resolutions much smaller than the focus size. Usually, th…
Ptychographic reconstruction with wavefront initialization
Felix Wittwer, Peter Modregger
X-ray ptychography is a cutting edge imaging technique providing ultra-high spatial resolutions. In ptychography, phase retrieval, i.e., the recovery of a complex valued signal fro…
Accelerating X-Ray Tracing for Exascale Systems using Kokkos
Felix Wittwer, Nicholas K. Sauter, Derek Mendez +7
The upcoming exascale computing systems Frontier and Aurora will draw much of their computing power from GPU accelerators. The hardware for these systems will be provided by AMD an…
Ptychographic characterization of polymer compound refractive lenses manufactured by additive technology
Mikhail Lyubomirskiy, Frieder Koch, Ksenia Abrashitova +9
The recent success in the development of high precision printing techniques allows one to manufacture free-standing polymer structures of high quality. Two-photon polymerization li…
