Abstract

Response times of fiber Bragg grating (FBG) temperature sensors are investigated. The response model is established and three types of sensors, including bare, gold-coated, and ceramics packaged FBG, are employed to measure their response time under a step simulation. The matched FBG method is used to obtain the response times. Each FBG sensor is measured 5 times and the average values of the sensors are 8.9 ms, 12.3 ms, and 336 ms, respectively. The results are useful for temperature measurement caring about time characteristic.

摘要

对光纤布拉格光栅（FBG）温度传感器的响应时间进行了研究。建立了响应模型，并采用三种类型的传感器，包括裸光纤布拉格光栅、镀金光纤布拉格光栅和陶瓷封装光纤布拉格光栅，在阶跃模拟下测量它们的响应时间。采用匹配光纤布拉格光栅法获取响应时间。每个光纤布拉格光栅传感器测量5次，传感器的平均值分别为8.9毫秒、12.3毫秒和336毫秒。这些结果对于关注时间特性的温度测量很有用。
