研究了空间分布的光纤应变传感器及其在振动检测中的应用．其原理是由结构的各种振型的分析，选择对不同模态具有不同灵敏度的传感光纤分布方式．以偏振光纤制成的此类传感系统成功地使用在受到外部随机激励的电流变结构的检测和控制中．
The spatial distribution of optical fiber strain sensor and its application in vibration detection are studied. The principle is the analysis of various vibration modes of the structure, and selects the sensing fiber distribution modes with different sensitivities to different modes. Such sensing systems made of polarized fibers are successfully used in the detection and control of electrorheological structures that are externally excited randomly.
