Abstract

The status and goals of the W. M. Keck Observatory adaptive optics (AO) program are reviewed. The overall system design is discussed, followed by a more detailed presentation of the optical design. Included is a description of a method for focusing the wavefront sensor (WFS) on either natural guide stars (NGS) or laser guide stars (LGS). Also, a combination tilt and focus sensor is described that corrects both the global tilt ambiguity common to LGSs, but also for instability in the focus of the LGS due to changes in the altitude of the sodium layer.
