摘　　要：采用长周期光纤光栅边缘滤波方法,解调传感信号波长,避免原有仪器频繁调节波长扫描光栅导致的仪器坏损,提高了实验的便利性、数据获取的准确率和实验成功率;改用手工测量实验数据,完成数据整理、加工、计算及用图表展示实验结果,这些应用将有利于培养学生的学习能力和实践能力.A long-period optical fiber grating was applied to demodulate the signal wavelength based on edge filtering, which avoided the potential damaged to the instrument caused by adjusting the scanning grating too frequently. The improved experimental setup effectively promoted the conven- ience of operation, the accuracy of data acquiring and the success rate of the experiment. In addition, by manual operation in measuring, data processing, calculating and the experiment results displaying, the students could really cultivate their learning ability and practical ability.
