Abstract

Hartmann-Shack method is widely used in adaptive optics system for wavefront sensing.A data processing system i employed in the sensor for computing wavefront gradient,wavefront reconstruction and control.To get a wide control bandwidth,the system should reach the processing needs in real time.In this paper,a parallel processing architecture called pipeling multiple SIMD(PMSIMD) architecture is presented.In the system,image acqusltion,wavefront gradient computation(WFGC) and wavefront reconstruction computation(WFRC) are conducted in pipeline,at the same time,the SIMD architecture is employed in both of the WFGC and WFRC.The computer simulation experiment shows the system based on the PMSIMD architecture is capable of processing video images of l2SXl28 pixels at 1000 frames per second and the time delay is less than 1/4 of frame period. Keywords:parallel processing architecture,wavefront of algorithms
