Seminar: "Joint physical design and computed imaging in photography, microscopy, and nonlinear optics" by Daniel Marks

Friday, May 12, 2017 11:00 AM to 12:00 PM

Abstract:

The physical systems and computational algorithms that comprise imaging instruments are typically designed separately and the results are suboptimal.  Here we demonstrate the superiority of holistic imaging system design for which the image formation comprises inseparable hardware and software implementations.  The first example is a multigigapixel video camera, the AWARE Wide-Field, comprised of hundreds of sensors integrated into a multiscale optical system.  The second example is a method that applies radar aperture synthesis techniques to optical coherence tomography so that entire three-dimensional volumes can be resolved, even if details are not optically focused.  The final example is to combine ultrafast pulse shaping and the interferometric detection of coherent Raman scattering with with numerical inverse scattering techniques to image the molecular contents of biological tissues and identify compounds.  While computation is required for these methods to work, instruments of greatly increased versatility and flexibility result, benefits already realized with other imaging non-optical modalities such as Synthetic Aperture Radar and Magnetic Resonance Imaging.
