摘　　要：从光纤光栅温度传感方程出发,对光纤光栅温度传感进行了理论分析.结合实验条件,自主设计了一套基于光纤光栅的温度传感实验装置.采用恒温水浴装置控制光纤光栅的温度,并通过实验对光纤光栅的温度特性进行了定量研究.结果表明:光栅中心波长与温度之间存在良好的线性关系,两者之间响应系数为0.010 57nm/℃,与理论计算结果比较吻合.此外,该实验装置结构简单、配件独立、拆装灵活,可应用于本科生专业课程的实践性教学环节,有助于丰富教学内容、完善教学手段、提高学生的学习能力和实践能力,并最终实现科研教学水平的同步提高.The temperature sensing principle of fiber grating is analyzed theoretically from fiber grating temperature sensing equation,the experimental device for fiber grating temperature sensing is designed independently.The temperature of fiber grating is controlled by constant temperature water bath and the temperature characteristics are studied quantitatively.The results show that the central wavelength of fiber grating has a good linear relationship with the temperature,in which response coefficient is 0.010 57nm/℃.The results agree well with the theoretical calculation. Because of concise structure, unattached accessories and flexible installation,the experimental instrument can be used in undergraduate course teaching.The work in this paper can be helpful for enriching the teaching content,improving the teaching method,enhancing the studentslearning ability and practical ability.It can effectively improve research and teaching work simultaneously.
