摘要
综述了光纤布喇格光栅反射波长移位的探测方法。提出一种新的压电陶瓷 -应变片组合探测光纤布喇格光栅反射波长的方法 ,它具有波长移位探测精度高、线性度好、结构紧凑等优点。
A detection method for the reflected wavelength shifting caused by optic fiber Bragg grating is described. A method for detecting the reflected wavelength with Bragg grating by combination of piezoelectric ceramic with strain gauge is put forward. The method has the advantages of high accuracy, good linearity and compact structure.
