Core Concepts
PtychoDV is a novel deep learning model that combines a vision transformer with a deep unrolling network to efficiently reconstruct high-quality images in ptychography, outperforming existing methods while reducing computational costs.
Abstract
Ptychography captures overlapping snapshots of samples with a moving probe.
