| 摘要 |
The present invention relates to a deformation measuring device capable of being formed as a single line by using an FBG optical fiber sensor and optical coupler and measuring the deformation rate of a structure in three dimensions. The deformation measuring device comprises optical fiber one of which is connected to an optical switch; a three-point connected to the end of the optical fiber; first optical fiber branched in an X-axis direction through the three-point connector; second optical fiber branched in a Y-axis direction through the three-point connector; and third optical fiber branched in a Z-axis direction through the three-point connector. |
