【Abstract】 A novel fiberoptic sensor array which is made of two-surface asymmetric pe-riodically etched multimode optical fibers is presented. It may be applied to detection ofstructure state such as stress, strain or damage assessment is smart material and struc-tures. The technology of array sensing signal processing in artificial neural network isdescribed. The simulation results of BP network and Kohonen network are also given.更多还原
