Phase retrieval by fixed point algorithmsPDE and Applied Math Seminar
|Speaker:||Albert Fannjiang, UC Davis|
|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.
