摘要
完成以高速FPGA技术为核心,实现根据外部需求使用外触发同步控制的线阵CCD采集光谱信号的驱动。通过测试,设计的CCD驱动采样固定延时时间为2.8099μs,延时精度不大于86.1 ns,线阵CCD采集到的光谱信号满足光谱分析要求。设计实现外触发方式控制TCD1304采集光信号,可以为后期工业测试提供应用参考。
Based on high-speed FPGA technology,the driving research of collecting spectral signal was realized by using line array CCD controlled by external trigger synchronization according to external demand. According to the test data in this paper,it could be seen that the fixed delay time of the designed circuit board was 2.809 9 μs,and the delay accuracy was no more than 86.1 ns,and the spectral signal collected by the linear array CCD could meet the requirements of spectral analysis. This paper designs and realizes the optical signals collected by the external trigger mode to control the TCD1304,providing application reference for later industrial testing.
