【摘要】 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。更多还原

【Abstract】 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.更多还原
