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.
