A detection method for the reflected wavelength shifting caused by optic fiber Bragg grating is described in the paper.
综述了光纤布喇格光栅反射波长移位的探测方法。
The interrogation technique was based on the use of two (or more) wavelength-matched fiber Bragg gratings (FBGs) to receive the reflected signal from the sensing FBG.
该技术利用两个（或多个）与传感光栅匹配的布喇格光纤光栅作为解调元件。
