| 摘 要： | 根据光纤中的布里渊散射附加频移与光纤所受的拉伸应变有关的特性，推导了附加频移与应变间的线性关系。在此基础上提出了利用光外差原理探测附加频移，从而实现应变探测的传感新方案，并分析了该方案能降低对激光源的线宽及频率稳定度要求之原因，给出了实验系统及实验结果。

| Abstract: | 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. |
