Colloquium: Thursday, October 8, 4:10 PM, Lewis Lab 316
Physics and Imaging Applications of Optical Vortices
Professor of Optical Physics
Rochester Institute of Technology
Vortices are ubiquitous in nearly every physical system and at every size scale. The physics of circulating systems continues to perplex scientists (often leading to Nobel prizes) and enable engineers. This talk will introduce the concept of scalar coherent optical vortices, and describe how they enable the imaging of exoplanets by the use of an optical vortex coronagraph. A description of some rather beautiful mathematical properties that account for the remarkable properties of this device will conclude the talk.
Physics and Astronomy Colloquia are usually scheduled for Thursdays at 4:10 PM in Lewis Lab room 316. Refreshments and snacks are available in the nearby coffee room at 3:45 PM.
