摘　　要：基于光纤法珀应变传感器的基本原理,阐述了两只光纤法珀应变传感器并联条件下的组合输出信号。讨论了离散腔长变换的方法用于复用组合输出光信号进行解调的原理。最后,通过计算机仿真和实验验证了此方法的可行性。It analyses the output intensity of two parallel multiplexed fiber Fabry-Perot strain sensors, based on the principle of the fiber Fabry-Perot strain sensors. Then the discrete gap transform method is proposed, and computer simulation is carried out to prove this method. Furthermore, the experimental system is set up and the experiment results show that the discrete gap transform method is reliable.
