摘要
为扩大传感光栅波长的解调范围,在原有级联长周期光纤光栅(CLPG)解调光纤布喇格光栅(FBG)系统的基础上增加了压电陶瓷,利用压电陶瓷的电致伸缩特性,实现对FBG的动态解调.系统仿真表明:加入压电陶瓷后CLPG的漂移量为1.6 nm,对传感光栅的解调范围增加了0.2 nm,并且提升了解调线性度.
In order to expand the demodulation range of sensing grating wavelength, piezoelectric ceramics are added to the original cascaded long period fiber grating (CLPG) demodulation system of fiber Bragg grating (FBG). The dynamic demodulation of FBG is realized by utilizing the electrostrictive characteristics of piezoelectric ceramics. The simulation results show that the drift of CLPG is 1.6 nm after adding piezoelectric ceramics, the demodulation range of the sensing grating is increased by 0.2 nm, and the demodulation linearity is improved.
