Distributed fiber temperature measurement
WebOptical fiber sensors for temperature and pressure have been developed for downhole measurement in oil wells. [8] [9] The fiber-optic sensor is well suited for this environment as it functions at temperatures too high for semiconductor sensors ( distributed temperature sensing ). WebApr 17, 2024 · According to our simulation, temperature sensitivity of 14.15 pm/°C is obtained for FBG sensor without any changes in the peak power. The strain sensitivity of 0.7837 pm/με, and a nonlinear sensitivity according to a quadratic function for peak power variation are also observed. 1 Introduction
