帧频2900Hz的高速实时波前处理机

波前处理机是自适应光学系统波前处理运算的中心 ,其运算延时直接影响系统的控制带宽。在 6 1单元自适应光学系统中 ,我们根据采样频率 2 90 0 Hz的Hartmann波前传感器输出信号的特点 ,采用流水和并行处理技术 ,用 1 2片TMS32 0 C5 0和 5片 TMS32 0 C31处理器 ,研制了我国首台峰值运算速度达 8.5亿次/秒的专用高速实时数字波前处理机 ,满足了系统的实时性要求。

290 0 Hz High Speed Real Time Wavefront Processor

High speed wavefront processor is the heart in adaptive optics system wavefront processing operation,its operation delay will directly affect the control bandwith of system.In this6 1 - element adaptive optics system,the pipeline and parallel processing techniques are adopted according to the features of the output signal of Hartmann wavefront sensor with 2 90 0 Hz sampling frequency.We developed a special high speed real- time digital wavefront processor with1 2 - chip TMS32 0 C5 0 and 5 - chip TMS32 0 C31 processors.This is the first wavefront processor with peak operation speed as high as85 0 ,0 0 0 ,0 0 0 /s,thus the real time requirements of the system can be fulfilled.
