摘要

本文介绍了光纤布拉格光栅测温结果的相关性研究的结果。结果表明，fbg不仅具有不同的初始灵敏度，而且在较窄的温度范围内(-30 ~ +70℃)也表现出非线性。结果表明，要将光纤光栅用作温度传感器，必须对光纤光栅进行温度预校准。

IDENTIFICATION OF TEMPERATURE SENSITIVITY DETECTOR ON FIBER BRAGG GRATING (FBG) SENSOR

The article presents the results of work on the study of the dependence of the results of temperature measurements using fiber Bragg gratings (FBGs). It was found that FBGs not only have different initial sensitivity, but also exhibit nonlinearity even in a narrow temperature range (from –30 to +70 °C). It is shown that to use the FBG as temperature sensors, it is necessary to precalibrate the FBG by temperature.
