基于布里渊光学相关域反射技术，实现了光纤中高空间分辨率的分布式应变传感。成功地测量了3cm光纤截面的布里渊频移，空间分辨率为13mm，采样率为50Hz。该空间分辨率是基于布里渊的反射计中有史以来报道的最好结果。
Distributed strain sensing with a high spatial resolution is demonstrated in optical fibers based on Brillouin optical correlation-domain reflectometry. The Brillouin frequency shifts of 3-cm fiber sections are successfully measured with a spatial resolution of 13 mm and sampling rate of 50 Hz. This spatial resolution is the best result ever reported in Brillouin-based reflectometry.
