Talk Title: Phase imaging with partially coherent light

Talk Abstract: This talk will describe computational phase imaging methods based on intensity transport, with a focus on imaging systems using partially coherent illumination (e.g. optical and X-ray microscopes). Knowledge of propagation dynamics allows quantitative recovery of wavefront shape with very little hardware modification. The effect of spatial coherence in typical and ‘coherence engineered’ systems will be explored. All of these techniques use partially coherent light, whose wave-fields are inherently richer than coherent (laser) light, having many more degrees-of-freedom. Measurement and control of such high dimensional beams will allow new applications in bioimaging and metrology, as well as bring new challenges for efficient algorithm design.

Speaker's Biography: Laura Waller the newest faculty member in the department of Electrical Engineering and Computer Sciences (EECS) at UC Berkeley, building a lab in computational optical imaging, with a focus on higher-dimensional wave-fields (such as partially coherent or nonlinear beams). She was a Postdoctoral Research Associate in Electrical Engineering and Lecturer of Physics at Princeton University from 2010-2012 and received B.S., M.Eng., and Ph.D. degrees in EECS from the Massachusetts Institute of Technology (MIT) in 2004, 2005, and 2010, respectively, where she was a SMART student (Singapore-MIT Alliance for Research and Technology).
