Abstract

We demonstrate a Brillouin optical frequency-domain reflectometry (BOFDR) technique, which can measure the strain and/or temperature along an optical fiber with one-end access, by detecting the spontaneous Brillouin scattering from a sinusoidally modulated pump light. Compared to the Brillouin optical frequency-domain analysis (BOFDA), we show that BOFDR measurements are free from the distorting components related to acoustic wave modulation, thus simplifying data processing.

摘要

我们展示了一种布里渊光频域反射测量法（BOFDR）技术，该技术通过检测来自正弦调制泵浦光的自发布里渊散射，能够在光纤一端接入的情况下测量沿光纤的应变和/或温度。与布里渊光频域分析（BOFDA）相比，我们表明BOFDR测量不受与声波调制相关的失真分量影响，从而简化了数据处理。
