| Abstract: | The technology of linear distributional optical fiber sensor is introduced,based on the mechanism of spiral distributed optical fiber sensor,and the relation between sliding distance and loss are studied by experiments.A optical fiber sensor with high resolving distance and broad dynamic range is designed,and the technology to expand the dynamic range and embedding process is discussed.The result shows that the distributed optical fiber sensor,which combines the sprial sensor with the linear one... |
