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

摘要

Disclosed is an apparatus for measuring displacement of a slope surface by using an optical fiber Bragg grating sensor. The apparatus includes a sensing unit configured to detect displacement of a slope surface by using an optical fiber; and a displacement meter connected to one end of the sensing unit to measure the displacement of the slope surface according to a change in length of the optical fiber, wherein the optical fiber includes a communication optical fiber manufactured by using a quartz glass material.
