摘要:
对相移光纤光栅(PS-FBG)的横向受力特性进行了理论和实验研究.采用传输矩阵法分析了PS-FBG的传输特性,并建立了光栅横向受力数学模型.理论分析表明,光栅透射谱阻带中的透射窗口在横向受力时会产生光谱分裂,且分裂距离与所受横向压力的大小成正比关系.实验在0～1 N的横向压力条件下,获得了1.4×10-3 N/mm的灵敏度,实验结果与理论模拟相符.
Abstract:
The characteristic of phase-shifted fiber Bragg grating(PS-FBG)under transverse force was studied theoretically and experimentally.Based on the transfer matrix method,the transmission spectral characteristics of PS-FBG are analyzed,and the corresponding mechanical models for the PS-FBG under transverse force are established.The theoretical analysis suggests that the narrow central transmission window is split with splitting distance is linearly proportional to the applied transverse force.Under the transverse force conditions of 0-1 N,a force resolution of 1.4×10-3 N/mm is obtained.The experiment results agree well with the simulation results.
