摘要 | In order to meet the demands of a mobile vehicle-based adaptive optical system, the traditional wave-front processor hardware architecture was redesigned. In this study, we combined a wave-front processing board, wave-front processing daughter board and DA conversion board, using optical fiber for board communication. In this way, the reliability of the system was improved while the functional requirements were satisfied. Meanwhile, the wave-front processor is the computing center of the closed-loop control of the adaptive optical system, and its operation delay directly affects the control bandwidth of the system. This paper presents a multi-pipeline adaptive real-time wave-front processing method based on FPGA to complete the slope calculation, restoration calculation, and control calculation. For the adaptive optical system, which can provide two-stage precision tracking and consists of 97 sub-apertures and 97 deformation mirrors, the processing delay is 506.25 s, meeting the requirement of 1 500 Hz real-time wave-front processing. 2018, Science Press.
