| Abstract: | 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. |
