Contrast-invariant deep ptychography neural networks
Albert Vong, Steven Henke, Oliver Hoidn +6
Ptychography neural networks suffer from scaling inconsistencies when generalizing out of distribution, limiting their real world viability. We address this scaling mismatch using…

Towards single-shot coherent imaging via overlap-free ptychography
Oliver Hoidn, Albert Vong, Aashwin Mishra +2
Ptychographic imaging at synchrotron and XFEL sources requires dense overlapping scans, limiting throughput and increasing dose. Extending coherent diffractive imaging to overlap-f…

Towards generalizable deep ptychography neural networks
Albert Vong, Steven Henke, Oliver Hoidn +8
X-ray ptychography is a data-intensive imaging technique expected to become ubiquitous at next-generation light sources delivering many-fold increases in coherent flux. The need fo…
