提出了一种基于匹配光栅调谐光纤激光器波长扫描寻址的新型光纤光栅复用传感解调方案, 理论上分析了系统的响应特性, 实验上完成了三光栅复用温度传感, 实验结果与理论值相一致。

A new approach for demodulation of the multiplexed fiber Bragg grating sensor system based on the use of wavelength-matched fiber grating tuned fiber laser to interrogate the sensing gratings is proposed. The response characteristics have been analyzed theoretically. Experimental results of three grating sensors multiplexed system are presented for temperature measurement, which agree well with theoretical ones.
