报告摘要:Planets that orbit distance stars are called exoplanets.
Before 1992 there were no known exoplanets.  Today the number
is roughly 2,000.  Very few of them have been directly observed.
Instead, most have been discovered with the space telescope called
Kepler by examining the variable brightness of a star when a
planet passes in front of it. Astronomers are curious to image
exoplanets because it would allow them to seek signs of life in
the spectrum of the collected light. In this talk I will discuss exoplanets
and describe an instrument called the optical vortex coronagraph that
allows astronomers to block starlight and form direct images of

exoplanets.


报告人简介: Dr. Grover Swartzlander is Associate Professor in  Chester F. Carlson Center for Imaging

 Science, Rochester Institute of Technology (RIT), USA. He has been editor-in-chief of the Journal of the

Optical Society of America B since 2013, and is/was Optical Society of America Fellow (2003), NASA NIAC

 Fellow (2011,2012), Cottrell Scholar (1996), NSF Young Investigator (1994). Dr. Swartzlander is currently

 exploring experimental and theoretical topics in the field of physical optics (imaging, flying by light, optical

vortices).  These include sub-resolution imaging, high contrast imaging, vortex phenomena, solar sailing,

and radiation pressure forces and torques. He has conducted pioneering research on the optical vortex

coronagraph, optical vortices, solitons, coherence theory, optical tweezers, and optical lift.  He joined RIT in 2008 after appointments at the University of Arizona, the Worcester Polytechnic Institute, and the US

Naval Research Lab.
