Abstract EN
Optical fiber sensing has the potential to overcome weak points of traditional electric sensors.
Many types of optical fiber sensors have been proposed according to the modulation parameter of incident light.
We have proposed an optical pulse correlation sensing system that focuses on the time drift values of the propagating optical pulses to monitor the temperature- or strain-induced extension along the optical fiber in the sensing region.
In this study, we consider the instability in the optical pulse correlation sensing system applied to remote monitoring over a kilometer-long distance.
We introduce a method to stabilize the instability of the pulse correlation signal resulting from the time drift fluctuation along a transmission line.
By using this method, we can purify the response and improve the accuracy of signals at the focused sensing regions.
We also experimentally demonstrate remote temperature monitoring over a 30 km-long distance using a remote reference technique, and we estimate the resolution and the measurable span of the temperature variation as (1.1/L)∘C and (5.9×10/L)°C, respectively, where L is the length of the fiber in the sensing region.
