In this thesis, based on the technique of optic fiber grating sensor and side-polishing method, the D-shaped fiber Bragg grating concentration sensor is studied and the experimental results are analyzed.

• 必须结合中间敏感物质(例如凝胶等化学物质)的使用，将浓度变化转化为应力变化，从而引起光纤布喇格光栅中心波长的偏移。 本文基于光纤光栅传感技术和侧面研磨技术，重点研究侧面研磨型光纤布喇格光栅浓度传感器，并对实验结果进行分析。
