Abstract: A new fiber optic sensor array which is made of asymmetiric periodically etched multimode optical fiber is described. It may be applied to detect structure state such as strain and stress, or damage assessment in smart material and structures. The method, model of array sensing signal processing in artificial neural network are decribed, and the simulation results of BP network are also given.

Key words: artifical neural network, fiberoptic sensing, smart material and structure
