摘　　要：在自适应光学系统中,波前复原是波前处理中运算量较大的部分,其运算速度直接影响波前处理机的实时性和系统的控制带宽。根据波前复原算法的特点,提出了用脉动阵列实现基于FPGA的实时波前复原处理方法,采用流水和并行处理技术,提高系统的吞吐率;极大地提高了运算速度。该方法实时性强,模块化程度高。In an adaptive optical system, wave-front reconstruction is a larger part of wave-front processing. Its operating speed directly affects the timeliness of the wave-front processor and control bandwidth of the system. A real-time wave-front reconstruction processing method based on FPGA with systolic array is proposed according to the characteristics of wave-front reconstruction algorithm. The handling rate of system is strengthened by using streamlined and parallel processing techniques and thus greatly improving the operation speed. The method has a strong timeliness and high modularity degree.
