基于时域分析，实现了保偏光纤中布里渊动态光栅光谱的分布式测量。利用布里渊频率分布图，通过泵浦光和探测光同步传输，获得了布里渊动态光栅的局域反射谱。在100 m范围内观察到高达−50.9 MHz/°C的大温度灵敏度，空间分辨率为2 m。
We demonstrate the distributed measurement of Brillouin dynamic grating spectra in a polarization-maintaining fiber based on time-domain analysis. Local reflection spectra of the Brillouin dynamic grating are acquired by synchronized propagation of the pump and the probe pulses based on the map of the Brillouin frequency distribution. Large temperature sensitivity as high as −50.9 MHz/°C is observed with 2 m spatial resolution in 100 m range.
