摘要
通过对应变波的传播过程分析,研究了应变传感器在低频情形下的动态特性,理论上给出了应变波传递到裸光纤上的传播时间和速度,并计算了应变传感器的工作频率.
The low frequency dynamic characteristics of a fiber bragg grating(FBG) strain sensor by analyzing transmit course of strain waves was investigated.The time and velocity for strain waves to transfer to bare FBG was calculated,the working frequency of FBG also estimated.
