Single-exposure X-ray dark-field imaging via a dual-energy propagation-based setup

Jannis N. Ahlers, Konstantin M. Pavlov, Marcus J. Kitchen +10

X-ray dark-field imaging visualises scattering from sample microstructure, and has found application in medical and security contexts. While most X-ray dark-field imaging technique…

Young double-slit interference with single hard x-ray photons

T. E. Gureyev, C. Hall, B. Arhatari +4

Young double-slit experiments using monochromatic hard X-rays with the energy of 25 keV are presented. The experiments were performed at a synchrotron source with a distance of 110…

Dielectric cross-shaped resonator based metasurface for vortex beam generation in Mid-IR and THz wavelengths

Raghu Dharmavarapu, Ken-ichi Izumi, Ikufumi Katayama +7

Metasurfaces are engineered thin surfaces comprising two dimensional (2D) arrays of sub-wavelength spaced and sub-wavelength sized resonators. Metasurfaces can locally manipulate t…

Experimental x-ray ghost imaging

Daniele Pelliccia, Alexander Rack, Mario Scheel +2

We report an experimental proof of principle for ghost imaging in the hard x-ray energy range. We used a synchrotron x-ray beam that was split using a thin crystal in Laue diffract…

Coherence Properties of Individual Femtosecond Pulses of an X-ray Free-Electron Laser

I. A. Vartanyants, A. Singer, A. P. Mancuso +33

Measurements of the spatial and temporal coherence of single, femtosecond x-ray pulses generated by the first hard x-ray free-electron laser (FEL), the Linac Coherent Light Source…
