摘要
详细介绍了非本征F-P光纤传感器的结构、特点和工作原理,阐述了非本征F-P光纤传感器在瓦斯检测系统中的应用。该传感器采用空芯光子晶体光纤作为载体,不受环境温度的影响,具有灵敏度高、抗干扰能力强、传输损耗小的特点,可显著提高瓦斯浓度检测的准确性和精度。
The structure,characteristics and working principle of extrinsic F-P sensor were introduced in details,and application of the extrinsic F-P sensor in gas detection system was expounded.The sensor takes hollow core photonic crystal fiber as isotopic carrier,is not affected by environmental temperature,which has characteristics such as high sensitivity,strong anti-jamming capability and low transmission loss,and can significantly improve accuracy and precision of gas concentration detection.
