Abstract

We experimentally demonstrated a distributed fiber sensor based on the hybrid Brillouin optical correlation-domain/time-domain analysis (BOCDA/BOTDA) employing noise- based phase modulation (PM). ∼23.8 cm spatial-resolution along ∼198 m polarization-maintaining fiber (PMF) was achieved.

基于噪声调制的混合BOCDA/BOTDA传感器实验研究

我们实验展示了一种基于混合布里渊光相关域/时域分析(BOCDA/BOTDA)的分布式光纤传感器，该传感器采用基于噪声的相位调制(PM)。沿~ 198 m偏振维持光纤(PMF)实现了~ 23.8 cm的空间分辨率。
