Abstract
This paper describes a set of detailed modes, set up in frequency domain and in time domain, that were used to support the analysis, design, test and performance verification phases of the SAAO Adaptive Optics (AO) System, which is being installed atop the 10000 ft Haleakala on the island of Maui in Hawaii. The AO system consists of a 941 actuator deformable mirror, a state-of-the-art 32 by 32 channel wavefront sensor and high speed reconstructor and control electronics, a high bandwidth fast steering mirror and sensor for tracking and jitter control, and the various other optical elements that are essential to close the AO loops. The high fidelity of the mode, which includes details such as the optical misregistrations, timing latencies, wave optics and atmospherics, allows us to tune it to match test results. Thus anchored, the mode is then sued to make performance predictions. The model provides a valuable tool in understanding and testing such highly complex electro- optic systems.
