摘　　要：针对布喇格光纤光栅(FBG)同时测量应变和温度时测量精度低的问题,提出了利用双芯长周期光纤光栅(LPFG)对应变和温度同时测量的方案。描述了方案的原理和实现方法,并通过仿真和数值计算验证了方案的性能。Focusing on the problem of low measurement accuracy of fiber Bragg gating measurements strainand temperature simultaneous, this paper proposes a program to use double-core long-period fiber grating tomeasure strain and temperature simultaneously. It describes the principle and implementation ofprograml andthrough simulation and numerical calculations verifing the performance of the program.
