用不同周期重叠写入的光纤Brass光栅对应力／温度实现同时区分测量。用应力／温度调制技术和信号解调方法，得到实验结果与理论的误差分别小于40με和0.5℃。可在复合材料、大型建筑物、抽油和输油管线中对应力和温度实现同时分布式智能化传感测量。
Fiber Brass gratings written in different cycles overlay enable simultaneous discrimination of stress and temperature. With the stress / temperature modulation technique and the signal demodulation method, the experimental results and theoretical errors are less than 40με and 0.5 ℃ respectively. Simultaneous, distributed, intelligent sensing of stress and temperature in composite materials, large buildings, pumping and pipelines.
