From phase retrieval to blind ptychography
范姜群健教授University of California, Davis 上午 10:30–12:00 鴻經館 107 室Abstract：
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.
