不对称刻纹光纤传感阵列及其神经网络处理

ASYMMETRIC ETCHED OPTICAL FIBER SENSOR ARRAY AND ITS NEURAL NETWORK PROCESSING

描述了一种适用于机敏材料及其结构中应力、应变等状态探测与损伤估计的新颖的光纤传感阵列．采用的是周期性不对称刻纹多模光纤组成的传感阵列，探讨了其信号的神经网络处理方法，给出了BP网的仿真结果．

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.
