Abstract

According to the particularity of the detected signals by distributed optical fiber temperature sensor

a weak signal detection scheme specially for distributional optical fiber temperature sensor system is presented based on the conventional weak signal detection method.By combining software and hardware

weak signal can be effectively extracted from strong noises to achieve higher signal-to-noise ratio.The components and devices in this scheme are general with lower cost

and the whole detection time is short.
