摘要
论述了为对结构的正常监控而利用光纤传感系统同时测量应力、温度和振动的新颖技术.该测量系统包含2个光学系统:一为波扫描的光纤激光器(WSFL)系统,一为利用波分多路调制器(WDM)的激光二极管系统.利用WSFL的光纤布拉格光栅(FBG)和非固有的法布里-珀罗(Fabry-pevot)干涉器(EFPI),组成混合传感系统(FBG/EFPI).借助于上述测量系统,可同时测量应力、温度和振动频率.
A new technology applied to measure simultaneously the stress, temperature and vibration trequency by using the optic fiber sensor in order to monitor normally the structure is discussed. The measuring system is composed of two optic sub-systems, one is the wave scanning optic fiber laser （WSFL） system, other is laser diode system using wave dividing modulator （WDM）. The fiber Bragg grating （FBG） of WSFL and EFPI are combined into integrated sensor system （FGB/EFPI）. With such system, the stress, temperature and vibration frequency can be measured simultaneously.
