Seminar: “Sparsity-Based Sub-Wavelength Imaging and Super-Resolution in Time and Frequency" - Dr. Moti Segev CREOL 102 Monday, February 21, 2011 / 11am-12pm

Abstract:

We demonstrate the recovery of sub-wavelength optical images based on prior knowledge that the object is sparse, and its analogous concept in the time and frequency domains, recovering temporal features much shorter than the response time of a photodetector and spectral features beyond the resolution of the spectrometer.

Biography:

Moti Segev is a Distinguished University Professor and the Trudy and Norman Louis Professor of Physics, at the Technion - Israel Institute of Technology, Haifa, Israel. He received his B.Sc. and D.Sc. from the Technion, Israel, in 1985 and 1990, respectively. Moti Segev has spent one year at Caltech as a post-doctoral fellow and two more years as a Senior Research Fellow. He joined Princeton in September of 1994 as an Assistant Professor, becoming an Associate Professor in 1997, and a Professor in 1999. In the summer of 1998, Moti Segev went back to his home country, Israel, and joined the Technion, eventually resigning from Princeton in 2000.

Moti Segev's research interests are mainly in Nonlinear Optics, Solitons, Lasers and Quantum Electronics, although he finds much entertainment in more demanding fields such as basketball and hiking. He has more than 250 publications in refereed journals, 11 book chapters, and has given more than 100 invited, keynote, and plenary presentations

at conferences.

Among his most significant contributions are the discoveries of photorefractive solitons, of random-phase solitons (also called incoherent solitons, or self-trapping of solitons made of incoherent white light, the first observation of 2D lattice solitons, and the first experimental demonstration of Anderson localization in a disordered

periodic system.

Moti Segev is a Fellow of OSA and APS. He has won several awards, among them the 2007 Quantum Electronics Prize of the European Physics Society and the 2009 Max Born Award of OSA.
