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.
