| 摘 要： | 提出了一种基于匹配光纤布拉格光栅的光栅温度传感新型多路解调方案,利用微机控制步进电机对多路匹配光栅施加压力和拉力从而与测量光栅匹配,达到对温度传感信号的解调。并对实验数据进行处理,建立了系统的响应特性模型。实验结果证明,该解调方法测量简单,重复性好,准确度较高。

| Abstract: | A novel multichannel demodulation scheme for fiber Bragg grating temperature sensing is proposed.In this scheme,temperature sensing signals are demodulated by tracing matching FBGs,pressure and tension are imposed by computer controlled step motor to multichannel matching FBGs. After experiment data processing, the response characteristics model of the system is established. It is proved that the demodulation method has characteristics of easy mearurement,good repeatability and high accuracy. |
