Electron volt energy resolution with ptychography using a broadband continuum spectrum
Silvia Cipiccia, Wiebe Stolp, Luca Fardin +6
Ptychography is a scanning coherent diffraction imaging technique successfully applied in the electron, visible and x-ray regimes. One of the distinct features of ptychography with…
Optics for broadband x-ray ptychography
Wiebe Stolp, Silvia Cipiccia, Darren Batey +1
In conventional x-ray ptychography, diffraction data is collected by scanning a sample through a monochromatic, and spatially coherent, x-ray beam. A high-resolution image is then…
Revealing Nanoscale Ni-Oxidation State Variations in Single-Crystal NMC811 via 2D and 3D Spectro-Ptychography
Ralf F. Ziesche, Michael J. Johnson, Ingo Manke +9
Enabling lithium (Li)-ion batteries with higher energy densities, longer cycle life, and lower costs will underpin the widespread electrification of the transportation and large-sc…
Compact laser-driven plasma X-ray source for time-resolved diffraction, spectroscopy, and imaging experiments at ELI Beamlines
Yelyzaveta Pulnova, Tomáš Parkman, Borislav Angelov +11
Experimentally measured characteristics of a kHz laser-driven Cu plasma X-ray source that was recently commissioned at ELI Beamlines facility are reported. The source can be driven…
Plug-and-Play Half-Quadratic Splitting for Ptychography
Alexander Denker, Johannes Hertrich, Zeljko Kereta +3
Ptychography is a coherent diffraction imaging method that uses phase retrieval techniques to reconstruct complex-valued images. It achieves this by sequentially illuminating overl…
Sampling requirements in near-field ptychography
L. Fardin, Y. Pulnova, T. Parkman +10
Ptychography is a robust lensless form of microscopy routinely used for applications spanning life and physical sciences. The most common ptychography setup consists in using a det…
