仿真FBG传输特性，共三个函数，利用光纤的传数矩阵和耦合模理论，可在main函数中修改参数-Simulation FBG transmission characteristics of the three functions, the use of optical fiber transmission matrix and coupled-mode theory, the parameters can be modified in the main function

对于光纤信号,经耦合器之后,在labview中实现对信号的还原。。(For fiber optic signals, the signal is restored in the LabVIEW after the coupler is applied..)
