摘要：
We developed an adaptive optics system which consists of a Shack-Hartmann wave-front sensor, a multi-channel deformable mirror, and a control computer. In this paper, the instrumentation of the adaptive optical system and the closed-loop wave-front correction algorithm are described. Also. the experimental results of the closed-loop wave-front correction are presented. A distorted He-Ne laser wave-front of 3.288 wavelengths of P-V values was corrected to 0.34 wavelengths of P-V values. The wave-front correction speeds using direct and indirect correction methods were 3 Hz and 1 Hz. respectively.
