Phase retrieval by fixed point algorithms

PDE and Applied Math Seminar

Speaker: Albert Fannjiang, UC Davis
Location: 3106 MSB
Start time: Mon, Apr 23 2018, 3:10PM

We first review uniqueness theorems for phase retrieval with a coded diffraction pattern and discuss how non-uniqueness ruins phase retrieval with a plain diffraction pattern.

We then present recent progress in uniqueness issues for ptychography and blind ptychography, which does not assume the knowledge of the mask.
