A novel high-sensitivity fiber-optic temperature sensing system based on the optical pulse correlation principle is proposed. The optical pulse correlation state corresponding to the time drift in fiber-optic transmission lines is detected by a second harmonic generation (SHG) crystal. This sensing system is combined with 3- and 100-m-long monitoring fibers using a time-division multiplexer (TDM) combination technique. By using the linear trend-line method to combine the correlation values of short and long monitoring fibers, a high-temperature sensitivity of 0.001 °C/mV and an approximatly 20 °C dynamic measurable range are successfully achieved.

“…One FBG temperature sensor, which is described in ref. 5, has high sensitivity and can reach 0.005 C resolution but its measurable range is limited. There are a few other types of temperature sensors, such as acoustic reflector temperature sensors, that also have low temperature sensitivity.…”
