摘要
光子晶体光纤传感器的稳定性在实际工程应用中具有重要影响。文章分析了光子晶体光纤压力传感器的基本原理,介绍了光子晶体光纤压力传感器的系统组成,从理论上分析了传感器系统相对于光源波长变化、输出信号光强起伏及环境温度波动的稳定性。光子晶体光纤压力传感器激光光源的输出功率及波长的波动、敏感元件长度的改变和环境温度的变化等都对整个传感器系统的稳定性有影响。
The stability of Photonic Crystal Fiber（PCF） sensors is of utmost importance in practical engineering applications.In this paper,the PCF pressure sensor model is derived in accordance with the elasto-optical theory,its system composition presented,and the variations of the system in relation to the optical source wavelength variations,output signal light intensity fluctuations and the ambient temperature stability theoretically analyzed.The fluctuations of its output power,wavelength,sensitive unit length and ambient temperature all exert impacts on the stability of the entire sensor system.
