Opto-Mechanical Design of ShaneAO: the Adaptive Optics System for the 3-meter Shane Telescope
Christopher Ratliff, Jerry Cabak, Donald Gavel +8
A Cassegrain mounted adaptive optics instrument presents unique challenges for opto-mechanical design. The flexure and temperature tolerances for stability are tighter than those o…
Woofer-tweeter deformable mirror control for closed-loop adaptive optics: theory and practice
Donald Gavel, Andrew Norton
Deformable mirrors with very high order correction generally have smaller dynamic range of motion than what is required to correct seeing over large aperture telescopes. As a resul…
ShaneAO: wide science spectrum adaptive optics system for the Lick Observatory
Donald Gavel, Renate Kupke, Daren Dillon +14
A new high-order adaptive optics system is now being commissioned at the Lick Observatory Shane 3-meter telescope in California. This system uses a high return efficiency sodium be…
Swimming with ShARCS: Comparison of On-sky Sensitivity With Model Predictions for ShaneAO on the Lick Observatory 3-meter Telescope
Srikar Srinath, Rosalie McGurk, Constance Rockosi +10
The Lick Observatory's Shane 3-meter telescope has been upgraded with a new infrared instrument (ShARCS - Shane Adaptive optics infraRed Camera and Spectrograph) and dual-deformabl…
Commissioning ShARCS: the Shane Adaptive optics infraRed Camera-Spectrograph for the Lick Observatory 3-m telescope
Rosalie McGurk, Constance Rockosi, Donald Gavel +16
We describe the design and first-light early science performance of the Shane Adaptive optics infraRed Camera-Spectrograph (ShARCS) on Lick Observatory's 3-m Shane telescope. Desig…
On-sky performance during verification and commissioning of the Gemini Planet Imager's adaptive optics system
Lisa A. Poyneer, Robert J. De Rosa, Bruce Macintosh +15
The Gemini Planet Imager instrument's adaptive optics (AO) subsystem was designed specifically to facilitate high-contrast imaging. It features several new technologies, including…
