摘要
应用逆压电效应 ,在低频或直流条件下 ,分析了光纤光栅与压电材料相结合的电压探头的传感性能 ,导出了Bragg反射波长位移量 ΔλB 随检测电压U之间的变化关系式 ;给出了PZT - 5H和SbSI两种压电材料与光纤光栅构成传感头的U、ΔλB、λB、ΔL/L四个参量之间的相互关系计算曲线 。
Using the converse piezoelectric effect , the sensing properties of integrating fiber grating with pizoelectric material for voltage sensing head under low frequence or direct supply conditions are analyzed in this pepar ,the relational expression of Bragg reflected wavelength λ B against detected voltage U is obtained uniting PZT-5H and SbSI two piezoelectrical materials with fiber grating,among U, Δ λ B ,λ B , Δ L/L four parameters for calculated curves are also given , and that is correlated with brief discussion.
