The 2D approximation quickly breaks down in reflection ptychography
Sander Senhorst, Stefan Witte, Wim Coene
Ptychographic reconstructions in reflection geometries are commonly interpreted with the same two-dimensional thin-sample model used in transmission, yet the validity of this appro…

Mitigating tilt-induced artifacts in reflection ptychography via optimization of the tilt angles
Sander Senhorst, Yifeng Shao, Sven Weerdenburg +3
Ptychography in a reflection geometry shows great promise for non-destructive imaging of 3-dimensional nanostructures at the surface of a thick substrate. A major challenge to obta…
