System for structural strain sensing by optical fiber sensor |
摘要 |
Disclosed is a fiber optic sensor system for sensing strain of the structure by using a wavelength swept fiber laser as a light source and using a fiber Bragg grating sensor as a fiber optic sensor, comprising: a reference fiber Bragg grating sensor, a fiber Bragg grating sensor array being branched from the reference fiber Bragg grating sensor through a coupler; a strain rate measuring coordinate signal-outputting means adapted to output an optical signal having a certain wavelength, an optical detector being connected to the coupler from which the fiber Bragg grating sensor group and the strain measuring coordinate signal-outputting means are branched for detecting output signals generated from the strain measuring coordinate signal-outputting means.
