Snapshot Ptychography on Array cameras

1 code implementation • 5 Nov 2021 • Chengyu Wang, Minghao Hu, Yuzuru Takashima, Timothy J. Schulz, David J. Brady

We use convolutional neural networks to recover images optically down-sampled by $6. 7\times$ using coherent aperture synthesis over a 16 camera array.

Multiscale Phase Retrieval

1 code implementation • 9 Dec 2020 • David J. Brady, Timothy J. Schulz, Chengyu Wang

Phase-sensitive sensor planes using such devices could eliminate the need both for lenses and reference signals, creating a path to large aperture diffraction limited laser imaging.
