Abstract

In order to increase the multiplying density of Fiber Bragg Grating (FBG) sensors, a novel FBG sensing network based on measuring point CDMA encoding technology has been developed. Furthermore, the necessary condition of measuring point CDMA code has been discussed and the measuring performances of this system have been analyzed. Simulation experiment indicates that in a spectral range of 25.5nm, this type of sensing network can arrange 41 FBG sensors and the measuring range of every sensor reaches 10 nm.
