Abstract
In consideration of the requirements of a large ground-based high resolution imaging telescope for the Wave-front Processor(WFP) of an adaptive optical system in output scales,processing speeds and control bandwidths,an adaptive optical system with thousand elements was explored.The adaptive optical WFP was composed of a master control computer,a wave-front processing host board and expandable wave-front processing sub boards and its output scale could reach the maximum of 1 200 elements.Large-scale logic devices were adopted as main processing chips,and a multithreading parallel pipeline algorithm was used to shorten the wave-front processing delay and promote the controlling bandwidth of the system.Then,an open loop experiment based on 961-element deformable mirror and a closed corrected experiment based on 137-element deformable mirror were performed.The result shows that the wave-front processing delay is 20.96 μs when the maximum sampling rate is 2000 frame/s,which demonstrates that the hardware expending circuit and multithreading parallel pipeline algorithm are feasible and effective for the wave-front processing of the adaptive optical systems.
