据我们所知，首次报道了芯直径为 50 μm 的全氟化渐变折射率聚合物光纤 (POF) 的分布式温度测量。布里渊光频域分析被证明能够以 4 m 的标称空间分辨率沿 20 米 POF 光纤样本空间解析与温度相关的布里渊频移分布。结果表明，POF 对于基于受激布里渊散射的分布式温度测量具有潜在的用途。
Distributed temperature measurements in a perfluorinated graded-index polymer optical fiber (POF) with 50-mu m core diameter are reported for the first time, to the best of our knowledge. Brillouin optical frequency-domain analysis is shown to be able to resolve spatially the temperature-dependent Brillouin frequency shift profile along a 20-m POF fiber sample, at a nominal spatial resolution of 4 m. The results indicate that POFs are potentially useful for distributed temperature measurements based on stimulated Brillouin scattering.
