| Abstract: | We used an adaptive optics system(to achieve tilt correction)in Lunar Laser Ranging.After describing in detail the principle of the correlation tracking for adaptive optics system,we present a wavefront processor based on the real-time operating system RTAI for correlation tracking.To achieve real-time processing of wavefronts,this wavefront processor adopts the absolute difference algorithm,a general-purpose CPU,and a Linux hard real-time extension system RTAI.As shown by experiments this processor is capa... |
