Title:

Snapshot Spectral Imaging, Focal Plane Interferometry and Compressive Imaging

Host:

Hong Hua

This talk describes coded aperture snapshot spectral imaging (CASSI) systems. CASSI systems rely on static aperture masks and decompressive data cube inference algorithms. We consider extensions of CASSI to alternative physical codes using interferometers or filters and we discuss application of snapshot spectral imaging to coherence imaging for 3D imaging and imaging through turbulence.

David Brady is Professor of Electrical and Computer Engineering at Duke University, where he leads the Duke Imaging and Spectroscopy Program (www.disp.duke.edu). Professor Brady graduated from Caltech in 1990 and was on the faculty at the University of Illinois at Urbana-Champaign from 1990-2001, when he moved to Duke to become the founding director of the Fitzpatrick Institute for Photonics. He specializes in computational optical imaging and spectroscopy, with a recent focus on snapshot spectral imaging systems using compressive sampling and nonlinear signal inference, multiaperture imaging systems and on spatial coherence sensing.
