DEVICE FOR MEASURING DISPLACEMENT OF SLOPE SURFACE BY USING FIBER BRAGG GRATING SENSOR

摘要

The present invention relates to a device for measuring the displacement of a slope surface by using a fiber Bragg grating sensor, the device comprising: a sensing part for sensing the displacement of a slope surface by using optical fiber; and a displacement meter which is connected to one end of the sensing part and which measures the displacement of the slope surface according to a length change in the optical fiber, wherein the optical fiber is provided with communication optical fiber manufactured using a material made of quartz glass, and thus can accurately measure displacement caused by the behavior of slope surfaces of mountains, roads, tunnels, and the like.
