Paper Abstract

This paper presents an adaptive optics (AO) system for a large IR telescope. The Keck Telescope on Mauna Kea is used as a case study. The system is designed to provide low-order wavefront correction using faint natural guide stars. It is shown that two innovations, namely the use of an AO-optimized CCD detector, and use of a variable control bandwidth, result in correction to a Strehl ratio of about 0.1 using guide stars of visual magnitude 18. Sky coverage is approximately 20% at this level of performance. Sky coverage rises to 100% at a Strehl ratio of 0.05.
