同时测量荧光光纤温度和应变的实验研究

Experimental Study on Dual Measurement of Strain and Temperature of Fluorescence Optical Fiber

利用掺杂铒元素荧光光纤的试验样品实验测试了荧光寿命的温度特性,并得到荧光寿命在不同温度下的应变响应关系.试验表明,荧光寿命会随着温度的升高而降低;与温度相比荧光寿命随应变的变化很小.提出了一个潜在的同时测量应变和温度的传感器模型.

An experiment system has been established. Some samples are produced to measured the fluorescence lifetime of temperature characteristic and get the relationship between strain and temperature versus the fluorescence lifetime at the same time. The experiment result was fitted and analyzed. The test results show that the fluorescence lifetime decreased with the increasing of temperature. The change of fluorescence lifetime with the strain is inconspicuous comparing to that with the temperature.
