Abstract
Optical fiber sensing has potential to overcome weak points of the traditional electric sensors. Many types of optical fiber sensors have been proposed according to the modulation parameter of incident light. We proposed optical pulse correlation sensing system which focuses the time drift values of the propagating optical pulses to monitor the temperature- or strain-induced extension along the optical fiber transmission line. In this study, we stabilize the pulse correlation signal instability due to the time drift fluctuation at the long transmission line to purify the response and improve the accuracy of signals at the focused sensing regions.
