对国内外已报道的强度解调型光纤布拉格光栅(FBG)传感器进行了综述,按解调方法将其归类为光栅匹配法、边缘滤波法、光栅啁啾法、激光匹配法和射频探测法。对各种方法的原理进行了介绍,对各自的优缺点等进行了评述,并对强度解调型FBG传感器的发展进行了展望。

The reported intensity-demodulated fiber Bragg grating (FBG) sensors are reviewed and classified into four types including the matched FBG method,filtering method,chirped-FBG method,laser matched method and radio frequency (RF) signal measurement method. The principls of these methods are introduced. Both the advantages and disadvantages of these methods are also discussed. And the development of intensity-demodulated FBG is forecasted.
