摘要: In 2004 January, the Big Bear Solar Observatory (BBSO) was equipped with a high-order adaptive optics (AO) system built in collaboration National (NSO) at Sacramento Peak. The hardware is almost identical to AO operated NSO Dunn Tower (DST), incorporating 97 actuator deformable mirror, Shack-Hartmann wave-front sensor 76 subapertures, and an off-the-shelf digital signal processor system. However, BBSO optical design quite different. It had be adapted 65 cm vacuum reflector downstream postfocus instrumentation. this paper, we describe design, demonstrate performance, use image restoration techniques illustrate quality that can achieved new
