15th Workshop on X-Ray Nano-Imaging of Biological and Chemical Systems at PETRA III

“The workshop gives attention to x-ray #microscopy at various PETRA III beamlines with special emphasis on
applications in #biology and #chemistry. Several scientific (multimodal) #XRay #imaging highlights are presented
with focus on the scanning X-ray microscopy beamlines P06, P10 and P05.”

First day of “Deep learning, image analysis, inverse problems, and optimization (DIPOpt)” was very fruitful. Three talks by Martin Storath, Odyssée Merveille, and Xiaohao Cai. In addition, I had the chance to present a poster on Electron Ptychography.

Scanning technique with overlapping illuminations, to invert far-field intensities into near-field amplitude and phase, and recover both object and illumination

But … why does it work?
