Fiber Optic Strain Sensing Technology with Brillouin Back-Scattering
Based on the phenomenon of the frequency shift in Brilluion back-scattering light related to the strain of the optical fiber, a new strain sensing scheme is proposed. On the basis of the nonlinear optics, the linear relationship between frequency shift of Brilluion scattering and the strain of the fiber is derived. The reason of the lower requirement for the band width and line stability of the laser source is analyzed. The experimental setup and result are presented.
