Abstract:
|
An embedded fiber Bragg grating (FBG) sensor, which fabricated in IMS, for
temperature sensing was proposed. The temperature responses of the in-fiber Bragg gratings
(FBGs) have been investigated. It was found that these responses ranged from 10.6 pm/°C to 12.0
pm/°C. The temperature sensitivity of the FBGs was 0.2°C. The strain responses remained
temperature independent over a temperature range of 20 – 180 C. The results obtained are in
agreement, within the experimental error, with predictions based on material parameters. Although
the temperature response is nonlinear over the temperature range 20 °C to 180 °C, in practical
systems the temperature response of the sensor may be assumed to be linear within the
temperature range 20 °C to 80 °C. |
