Characterization of Adaptive Optics at Keck Observatory: Part II

摘要

Adaptive optics (AO) has found widespread use in astronomical settings to compensate for atmospheric turbulence and telescope aberrations. At the W. M. Keck Observatory, there are identical adaptive optics systems on the Keck I and Keck II telescopes. In previous work, we described the components and the performance of the Keck AO system. This paper is a continuation of this characterization eort. In this paper, we focus on the problem of estimating the bandwidth and measurement noise errors. This is important because during an AO observation these are the only two terms that can be optimized to improve the performance.
