Over the 100 year history of phase retrieval, it has had broad application to x-ray crystallography, electron microscopy, diffractive imaging, DNA, x-ray tomography and much more. Phase retrieval will even be needed to align the mirrors of the new James Webb Space Telescope scheduled for launch in 2018. We will start with the history and fundamentals of phase retrieval and its applications which have garnered a dozen Nobel Prizes over the years. Only recently have mathematicians entered this area to give a solid mathematical foundation to phase retrieval. In the second half of this talk we will look at recent advances in the mathematics of phase retrieval.
Prof. Casazza is currently the Director of The Frame Research Center abd Curators’ Professor of Department of Mathematics of University of Missouri. Prof. Casazza worked for 25 years in functional analysis (Banach space theory) and then switched into applied math. He does research in functional analysis, (applied) harmonic analysis, operator theory, but his main research interest is in applications of Hilbert space frames to problems in mathematics, applied mathematics and engineering.
