Paper Abstract

This paper summarizes adaptive optics performance estimates obtained for the Gemini 8-m telescopes, with an emphasis on relatively low order systems employing Shack-Hartmann wavefront sensors, continuous facesheet deformable mirrors with zonal actuators, and either a natural guide star or a laser guide star in the mesospheric sodium layer. Adaptive optics performance is characterized in terms of the fractional encircled energy within a 0.1 arc sec detector at 2.2 microns under average seeing conditions at Mauna Kea. The increased sky coverage achieved using laser guide stars according to this definition of performance is significant, even for a relatively low order adaptive optics system designed for turbulence compensation at 2.2 microns at a good astronomical site.
