Hui Cao, John C. Malone Professor of Applied Physics, Professor of Physics, Professor of Electrical Engineering, Yale University, will give a talk on “Lighting Up Opaque Media.”
Abstract: Seeing through strong-scattering media such as white paint or human tissue has long been considered impossible. Recent developments of optical wavefront shaping techniques have enabled the experimental realizations of imaging and focusing light through turbid samples. We demonstrated coherent control of light transmission and absorption in diffusive systems by manipulating the interference of multiply scattered waves. We further add optical gain to a random medium to induce lasing action and apply the low-coherence emission for speckle-free full-field imaging.
Bio: Hui Cao is the John C. Malone Professor of Applied Physics and of Physics, and a professor of Electrical Engineering at Yale University. She received her Ph.D. degree in Applied Physics from Stanford University in 1997. Prior to joining the Yale faculty in 2008, she was on the faculty of Northwestern University from 1997 to 2007. Her technical interests and activities are in the areas of mesoscopic physics, complex photonic materials and devices, nanophotonics, and biophotonics. She authored or co-authored one monograph, twelve book-chapters, seven review articles and 260 journal papers. She is an elected member of the National Academy of Sciences, and the American Academy of Arts and Sciences.
