摘要
利用CPO技术设计了在掺铒光纤中实现光速的连续可调的实验.实验系统中利用LabVIEW和FPGA设计的信号发生器对激光信号进行内调制,信号经过掺铒光纤由数据采集卡传递到上位机,利用LabVIEW进行分析和处理.该系统可以简化数据分析过程,实现人机交互,便于实时监测分析.
An experimental system which could adjust the velocity of light continuously was proposed.Using LabVIEW and FPGA,signal generator could modulate light signal,and the signal passing through Erbium-doped fiber could be collected by DAQ,then transferred to PC and processed by LabVIEW.The system could simplify the data analysis process,achieve human-computer interaction and facilitate real-time monitoring.
