摘要
光子晶体光纤压力传感器可广泛用于各种压力环境监测中。文章分析了光子晶体光纤中光脉冲的传输特性,提出了相位调制型光子晶体光纤压力传感器的基本模型,对光子晶体光纤传感器基于光脉冲相位和光强的信号检测方案进行了讨论。光子晶体光纤传感器的压力敏感性高,而温度敏感远远低于传统的光纤传感器。光子晶体光纤传感器系统简洁、适用。
The application of the Photonic Crystal Fiber pressure sensor is broad in the environmental pressure monitoring.The transmission properties are analyzed in the Photonic Crystal Fiber, the basic phase modulation model of the Photonic Crystal Fiber pressure sensor is presented,the signal detecting methods based the pulse phase and intensity are discussed in the Photonic Crystal Fiber pressure sensor. The pressure sensitivity is greater and the temperature sensitivity is less than the ordinary fiber sensor in the Photonic Crystal Fiber pressure sensor,the Photonic Crystal Fiber pressure sensor is terseness.
