Abstract

Aiming at improving the sensitivity of OFDR distributed optical fiber temperature sensors, this paper introduces the design of a temperature sensor with a new structure. In this design, PDMS/Glycerol is coated on the surface of a SMF as a temperature-sensitive material. Within the temperature range from 30 °C to 150 °C, this sensor exhibits excellent temperature stability and repeatability, with an average relative deviation of only 0.16%, and its performance remains stable during temperature cycles. Furthermore, the temperature sensitivity of the sensor is 18.84 pm/°C, representing an 87% improvement compared to that of SMF.
