Comparative experiment study of distributed optical fiber temperature monitoring methods

To make out a reasonable reference to the choice of sensor in the field of optical fiber temperature sensing, these temperature measurement experiments were carried out, including fiber Bragg grating, optical fiber Brillouin scattering, Raman Scattering Fiber Optic sensors, which are all packaged with FRP suitable for engineering applications. Then temperature measurement results are obtained. Meanwhile, the temperature characteristics of these sensors can be known by comparison between not only on sensing principle but experimental data. This can be a useful reference for the application of fiber optic temperature sensor in the temperature monitoring field.
