| 摘 要： | 荧光光纤在光纤通信及光纤传感领域扮演着重要的角色．利用荧光衰减寿命作为传感参量，对荧光寿命随应变的响应关系进行了测试，根据实验数据对荧光光纤应变响应的物理机制进行了初步的分析．实验结果表明，该实验系统可实现对应变的测量，同时由于实验系统对温度的响应相对于应变的响应很小，所以可以忽略温度的影响，并针对于结果中所表现的荧光寿命的周期性的振荡现象做了理论的分析．

| Abstract: | Fluorescence fiber plays an important role in the fields of optical fiber communication and fiber optical sensors.By taking the decay time of fluorescence sensors as the parameters,the response relation between fluorescence lifetime and strain was tested.Based on the experimental data,the physical mechanism of the strain response of fluorescence fiber was analyzed preliminarily.The experimental result indicated this system can be used to measure strain and ignore the effect from temperature as the response ... |
