光纤光栅传感实验装置设计与实现

摘要

Fiber grating is one of the most potential and typical optical passive components .A large number of studies have shown that fiber grating is ideal for stress and temperature sensing element .Fiber grating has widely applicable perspective in many fields such as structure monitoring , electrical power , and communications industry .Combined with existing equipment ,an experiment about stress and temperature sensing is designed . Experiments are carried out to verify the basic characteristics of fiber grating while realizing the goal of monitoring of strain and temperature as well .Experimental results are discussed by using this experimental system ,the result of experiment is in accordance with theoretical analysis ’ conclusion .%光纤光栅是理想的应力和温度传感元件。结合实验室器件，设计了一个利用光纤光栅监测应力以及温度的实验系统。通过实验验证了光纤光栅的基本特性，实现了应力及温度的监测。通过自行搭建的实验平台进行了实验分析，实验结果和理论分析吻合。
