Abstract
Session2 (Adaptive optics, interferometry, and other approaches to mitigate atmospheric optical turbulence.)
Title'Adaptive optics using multiple guide stars'
AbstractOver the past several years, experiments in adaptive optics (AO) involving multiple natural and laser guide stars have been carried out by our group at the 1.5 m Kuiper telescope and the 6.5 m MMT telescope using multiple laser guide stars. From open loop data we have calculated the performance gains anticipated from ground layer adaptive optics and laser tomography adaptive optics. For the first time, we expect to close the AO control loop around five laser beacons in April 2007 where we predict image quality of <0.2" FWHM in K band over a 2' field. The work here is intended to be both its own productive scientific endeavor for the MMT, but also as a proof of concept for the advanced AO systems designed to support observing at the future Giant Magellan Telescope.
