Abstract

The time response relation of central position drift of FBG temperature sensor reflection wavelength is theoretically analyzed,influence of material,heat exchange coefficient,cladding and other factors on FBG temperature and time response speed is discussed.The temperature and time response characteristic of bare FBG in medium as well as the temperature and time response characteristic of FBG in cladding are respectively verified through experiment.Through experimental verification,the hysteresis quality of FBG sensor reflection wavelength central position drifts is greatly related to fiber optic materials,optical surface area and surface thermal conductance h.The larger the surface coefficient is,the shorter the retardation time of reflection wavelength central position drifts will be.The change rule conforms to the theoretical analysis results.

光纤光栅温度响应时间滞后规律的研究

从理论上分析了FBG温度传感器反射波长中心位置漂移的时间响应关系，讨论了材料、换热系数、包层等因素对FBG温度和时间响应速度的影响。通过实验分别验证了裸光纤光栅在介质中的温度响应特性和时间响应特性以及包层中光纤光栅的温度响应特性和时间响应特性。通过实验验证，光纤光栅传感器反射波长中心位置漂移的滞后质量与光纤材料、光学表面积和表面热导率h有很大关系，表面系数越大，反射波长中心位置漂移的滞后时间越短。其变化规律与理论分析结果一致。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
