Abstract :
In order to improve measuring precision, a neural network application in non-linear compensation of FBG sensing system, which is based on coarse wavelength division multiplexer (CWDM), was studied in this paper. Simulation results show that a perfect linearization was realized with the system characteristics after neural network compensation.
