Paper Abstract

The Keck Next Generation Adaptive Optics (KNGAO) system promises to yield high-Strehl observations over a wide range of science wavelengths from the optical through the infrared. We describe the algorithms proposed for a Real-Time Controller (RTC) implemented in a massive parallel processor environment. These algorithms take advantage of the Fourier domain to speed up processing and ensure minimum variance control that incorporates prior as well as current data. We present the unique approach to the design that enables such a complex tomography processor to scale more favorably with telescope aperture size than the more traditional RTC approaches.
