Development towards high-resolution kHz-speed rotation-free volumetric imaging
Eleni Myrto Asimakopoulou, Valerio Bellucci, Sarlota Birnsteinova +19
X-ray multi-projection imaging (XMPI) provides rotation-free 3D movies of optically opaque samples. The absence of rotation enables superior imaging speed and preserves fragile sam…
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,…
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…
Drill-bit-inspired dynamic focal fields for augmented laser materials processing
Evangelos Skoulas, Pinku Yadav, Justin Hidjam +8
The paper presents a drill‑bit‑inspired laser beam that dynamically rotates a two‑lobe Hermite‑Gaussian focus, allowing programmable energy deposition for more efficient metal mach…
Megahertz X-ray microscopy at X-ray Free-Electron Laser and Synchrotron sources
Patrik VagoviÄ, Tokushi Sato, Ladislav MikeÅ¡ +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…
Cavitation by phase shift of focused shock waves inside a droplet
Samuele Fiorini, Guillaume T. Bokman, Anunay Prasanna +6
Localized cavitation in liquids and soft tissues, typically initiated by the rarefaction phase of high-amplitude ultrasound waves, is leveraged in several biomedical applications s…
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…
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…
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…
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 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…
Shape modes and jet formation on ultrasound-driven wall-attached bubbles
Marco Cattaneo, Louan Presse, Gazendra Shakya +6
Understanding how substrate-attached bubbles respond to ultrasound is important for applications from industrial cleaning to biomedical therapy. Under ultrasonic excitation, bubble…
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…
Ghost projection. II. Beam shaping using realistic spatially-random masks
David Ceddia, Andrew M. Kingston, Daniele Pelliccia +2
