Abstract

In this paper, we demonstrated a FBG (Fiber Bragg Grating) temperature sensor only using an EDFA and a single FBG in the wireless sensors network. By means of detecting the intensity of the light reflected from the sensing FBG, we can obtain the surrounding temperature perturbation. Using EDFA and photoelectric cell in stead of BBS (broad band source) and OSA (optical spectrum analyzer) respectively, which significantly decreases the cost of the sensing system. Finally, the sensing information can be collected, processed, and transmitted to the control center via the wireless network. This kind of FBG temperature wireless sensor network combined both the advantages of fiber grating sensor and wireless communication, which provides potential commercial application in some special fields, where the conditional sensors will not be feasible.
