摘    要:提出一种基于白光干涉的光缆无损伤识别方法.将光纤的两端环接,入射光波经耦合器分成两束光,以相反的方向在同一根光纤中传播,用探测器接收另一端产生的信号.在外加作用力下,对并列在一起的两根光纤产生的光程变化进行了理论分析,推导出光缆识别系统输出信号的理论表达式,对系统输出的信号进行了仿真计算.分别利用冲击信号、正弦信号、音...

关 键 词:光缆识别  光纤  白光干涉  无损伤  声音识别

Abstract:A method of the lossless identification for fiber cable based on white-light interference is studied. When the two ends of fiber-optic are connected,the light-wave is coupled into two beams of light with the same light intensity and transmit in the opposite directions.Detector receives signals generated by the other side.The two optical fibers side by side with the force of outside and the optical fiber path changes are analyzed. The output signals on some conditions are simulated and verified by experiment...
Keywords:cable identification  fiber  white-light interference  lossless  voice recognition
