Self-supervised physics-informed generative networks for phase retrieval from a single X-ray hologram
X-ray phase contrast imaging significantly improves the visualization of structures with weak or uniform absorption, broadening its applications across a wide range of scientific disciplines. Propagation-based phase contrast is particularly suitable for time- or dose-critical in vivo/in situ/operando (tomography) experiments because it requires only a single intensity measurement. However, the phase information of the wave field is lost during the measurement and must be recovered. Conventional…

Directional Dark Field for Nanoscale Full-Field Transmission X-Ray Microscopy
Dark-field X-ray imaging offers unique insights into material structures by visualizing X-ray scattering rather than attenuation, revealing features invisible to conventional imaging techniques. While established approaches like grating-based and speckle-based imaging have demonstrated the utility of dark-field contrast in medical diagnostics and materials science, these methods have been primarily limited to laboratory and micro-CT systems. Building on the recent demonstration of dark-field im…
