TL;DR: Adaptive Optics (AO) will be essential for accomplishing many, if not most, of the science objectives currently planned for Extremely Large Telescopes including GMT, OWL, and TMT as mentioned in this paper.
Proceedings ArticleDOI
Progress on Altair: The Gemini North Adaptive Optics System
Glen Herriot,Simon L. Morris,Andre Anthony,Dennis Derdall,Dave Duncan,Jennifer Dunn,Angelic Ebbers,J. Murray Fletcher,Tim Hardy,Brian Leckie,A. Mirza,Christopher L. Morbey,M. Pfleger,Scott Roberts,Philip Shott,Malcolm Smith,Leslie Saddlemyer,Jerry Sebesta,Kei Szeto,Robert Wooff,W. Windels,Jean-Pierre Véran +21 more
TL;DR: The Gemini Adaptive Optics System, (Altair), under construction at the National Research Council of Canada's Herzberg Institute of Astrophysics is unique among AO systems designed with its deformable mirror (DM) conjugate to high altitude.
Journal ArticleDOI
Advanced vibration suppression algorithms in adaptive optics systems
TL;DR: This paper compares the most relevant solutions proposed hitherto to a novel multirate algorithm using the linear-quadratic-Gaussian (LQG) approach capable of upsampling the correction to further reduce the impact of vibrations.
Proceedings ArticleDOI
MCAO for Gemini South
Brent Ellerbroek,Francois Rigaut,Brian J. Bauman,Corinne Boyer,Stephen L. Browne,Richard A. Buchroeder,James W. Catone,Paul Clark,Celine d'Orgeville,Donald T. Gavel,Glen Herriot,Mark R. Hunten,Eric W. James,Edward J. Kibblewhite,Iain T. McKinnie,James T. Murray,Didier Rabaud,L. Saddlemyer,Jacques Sebag,James Stillburn,John M. Telle,Jean-Pierre Véran +21 more
TL;DR: The multi-conjugate adaptive optics (MCAO) system design for the Gemini-South 8-meter telescope will provide near-diffraction-limited, highly uniform atmospheric turbulence compensation at near-infrared wavelengths over a 2 arc minute diameter field-of-view.
Proceedings ArticleDOI
Focus errors from tracking sodium layer altitude variations with laser guide star adaptive optics for the Thirty Meter Telescope
Glen Herriot,Paul Hickson,Brent Ellerbroek,Jean-Pierre Véran,Chiao-Yao She,Richard Clare,Doug Looze +6 more
TL;DR: In this article, the laser wavefront sensors (WFS) on the mesospheric sodium layer are proportional to the square of the telescope diameter, due to improperly focusing laser WFS.
