Integrated Design of Fiber Bragg Grating (FBG) Sensing Pedagogical Experiments

本文针对光纤光栅传感实验教学中重验证，轻应用的问题，设计了光纤光栅传感的综合性教学实验。具体的实验内容包含了光纤光栅光谱特性测量，光纤光栅温度传感及隧道缩尺模型火灾监测。实验设计结合了光学和计算机技术，内容由浅到深，由验证到应用，难度适中，易于教学，学生参与度高。可有效增强学生对光纤光栅传感技术的理论理解和实验操作能力。This work proposes an integrated FBG sensing pedagogical experiment to bridge the gap between verification-based training and real-world applications in current curricula. The three-stage experiment encompasses fundamental FBG spectral analysis, temperature sensing implementation, applied fire detection in tunnel environments. By synergizing photonic principles with computational methods, this progressive framework fosters active learning while developing critical competencies in optical sensing systems.
