Design of mobile vehicle-based adaptive optical wave-front processor
摘要
Abstract
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 μs,meeting the requirement of 1 500 Hz real-time wave-front processing.关键词
