Single-shot imaging with randomized structured illumination at a free electron laser
Abraham L. Levitan, Kahraman Keskinbora, Matteo Pancaldi +4
Stroboscopic nanoscale imaging with free electron laser light is revolutionizing our understanding of fast dynamics in heterogeneous systems. The short wavelength of X-ray and extr…
Soft X-ray Reflection Ptychography
Damian Guenzing, Dayne Y. Sasaki, Alexander S. Ditter +9
Scanning transmission X-ray microscopy and ptychography have become mature tools for high-resolution, element-specific imaging of nanoscale structures. However, transmission geomet…
Nanoscale Domain Wall Dynamics in Micromagnetic Structures with Weak Perpendicular Anisotropy
Tim A. Butcher, Nicholas W. Phillips, Abraham L. Levitan +4
Time-resolved pump-probe soft X-ray ptychography and Scanning Transmission X-ray Microscopy (STXM) were employed to study the magnetic domain wall dynamics in microstructures of pe…
Single-shot X-ray ptychography as a structured illumination method
Abraham Levitan, Klaus Wakonig, Zirui Gao +4
Single-shot ptychography is a quantitative phase imaging method wherein overlapping beams of light arranged in a grid pattern simultaneously illuminate a sample, allowing a full pt…
