有关周一有讲座的通知

周一上午有两个讲座，欢迎各位研究生，博士生前往。

Title:Computational optical imaging and spectroscopy

SPEAKER:    Professor  David J. Brady

DATE:       May.18, 2009 

TIME:       9:40am

LOCATION:   教三-326 

Abstract:

Integrated design of optical encoding, sampling and image estimation algorithms in digital optical systems enables substantial improvements over conventional focal designs. This talk reviews computational designs for improving data efficiency, field of view, sensitivity, sensor volume and depth of field. Examples discussed include compressive spectroscopy, coded aperture snapshot spectral imagers, multiple aperture digital superresolution and photonic crystal filters.

Bio:

David J. Brady is Professor of Electrical and Computer Engineering at Duke University, where he leads the Duke Imaging and Spectroscopy Program. Professor Brady is the author of numerous technical papers and the textbook “Optical Imaging and Spectroscopy.” He is a Fellow of the Optical Society of America, SPIE and IEEE. He earned Ph. D. and M.S. degrees from the California Institute of Technology and a B.A. from Macalester College.

Brady is also Chief Scientist of Centice Corporation, which manufactures Raman spectrometers for pharmaceutical quality assurance, and Applied Quantum Technologies, which manufactures computational imaging systems.

Title:      Control Surface Plasmon-Polariton with Nanolayers

SPEAKER:    Dr. Junpeng Guo

DATE:       May.18, 2009 

TIME:       10:40am

LOCATION:   教三-326 

Abstract:

Plasmonic photonics is an emerging technology area which is leading to many potential applications for bio/chemical sensing, imaging, and data communication. Surface plasmons are the free electron density oscillations near the surface of metals. The conduction electron density oscillation is always coupled with an electromagnetic field. An important property of surface plasmons is the highly confined electromagnetic field near the plasmon resonance. Although surface plasmons can confine electromagnetic energy in the deep subwavelength scale, a fundamental problem is the energy dissipation/loss in metal materials. In this talk, I will review recent progresses in mitigating the loss of surface plasmon energy loss and techniques for engineering surface plasmons with nanolayers and nanostructures.
