Full-field fluorescence computed tomography (F3CT) using a calibrated virtual cone-beam pinhole geometry
Thomas Zillhardt, Yunhui Chen, Alexander Rack +4
We present F3CT, a synchrotron-based hyperspectral full-field fluorescence computed tomography technique that avoids raster scanning by combining a pinhole aperture with an energy-…
Drill-bit-inspired dynamic focal fields for augmented laser materials processing
Evangelos Skoulas, Pinku Yadav, Justin Hidjam +8
Laser manufacturing has advanced through increasingly precise control of power, pulse duration, repetition rate and scan trajectory, yet the spatial intensity profile of the beam i…
Direct volumetric reconstruction for highly compressive x-ray fluorescence ghost tomography
A. Ben-Yehuda, A. Rack, S. Shwartz +1
X-ray fluorescence (XRF) enables element-specific, nondestructive imaging, but conventional raster scanning scales poorly with sample size, particularly for tomography, because mea…
Ultrafast Radiographic Imaging and Tracking: An overview of instruments, methods, data, and applications
Zhehui Wang, Andrew F. T. Leong, Angelo Dragone +25
Ultrafast radiographic imaging and tracking (U-RadIT) use state-of-the-art ionizing particle and light sources to experimentally study sub-nanosecond dynamic processes in physics,…
Synchrotron-based X-ray Fluorescence Ghost Imaging
Mathieu Manni, Adi Ben-Yehuda, Yishay Klein +5
X-ray Fluorescence Ghost Imaging (XRF-GI) was recently demonstrated for x-ray lab sources. It has the potential to reduce acquisition time and deposited dose by choosing their trad…
Brittle fracture studied by ultra-high speed synchrotron X-ray diffraction imaging
Antoine Petit, Sylvia Pokam, Frederic Mazen +7
Ever since the very first human-made knapped tools, the control of fracture propagation in brittle materials has been a vector of technological development. Nowadays, a broad range…
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…
Boosting spatial resolution by incorporating periodic boundary conditions into single-distance hard-x-ray phase retrieval
David M. Paganin, Vincent Favre-Nicolin, Alessandro Mirone +6
A simple coherent-imaging method due to Paganin et al. is widely employed for phase-amplitude reconstruction of samples using a single paraxial x-ray propagation-based phase-contra…
3D characterization of the primary Al3Sc phases in an Al-Sc alloy using Synchrotron X-ray tomography and electron microscopy
Yuliang Zhao, Weiwen Zhang, Billy Koe +7
The three-dimensional structures of the primary Al3Sc particles in an Al-2Sc master alloy were studied by synchrotron X-ray microtomography, scanning and transmission electron micr…
Megahertz X-ray microscopy at X-ray Free-Electron Laser and Synchrotron sources
Patrik Vagovič, Tokushi Sato, Ladislav Mikeš +17
We demonstrate X-ray phase contrast microscopy performed at the European X-ray Free-Electron Laser sampled at 1.128 MHz rate. We have applied this method to image stochastic proces…
Phase-sensitive x-ray ghost imaging
Margie P. Olbinado, David M. Paganin, Yin Cheng +1
Imaging with hard x-rays is an invaluable tool in medicine, biology, materials science, and cultural heritage. Propagation-based x-ray phase-contrast imaging and tomography have be…
Ghost Tomography
Andrew. M. Kingston, Daniele Pelliccia, Alexander Rack +4
Ghost tomography using single-pixel detection extends the emerging field of ghost imaging to three dimensions, with the use of penetrating radiation. In this work, a series of spat…
Practical x-ray ghost imaging with synchrotron light
Daniele Pelliccia, Margie P. Olbinado, Alexander Rack +1
We present a practical experimental realization of transmission x-ray ghost imaging using synchrotron light. Hard x-rays from an undulator were split by a Si 200 crystal in Laue ge…
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…
