SYSTEM FOR MONITORING THREE-DIMENSION SHAPE OF PIPE-STRUCTURE USING FIBER BRAGG GRATING SENSOR

摘要

The present invention relates to a three-dimensional shape monitoring system. The present invention includes: a pipe wherein optical fibers are embedded; fiber Bragg grating sensors formed along a line of the optical fibers inside the pipe at preset intervals; a light transceiver to emit lights into the optical fibers embedded in the pipe, and receiving data of frequency signals reflected from the fiber Bragg grating sensor; and a computer estimating and monitoring the three-dimensional shape and position of the pipe based on the data of the frequency signals received by the light transceiver. According to the present invention, an effect of easily monitoring the three-dimensional shape and strain of the pipe using the fiber Bragg grating sensor is obtained.
