提出了一种双频调制方案，用于单激光布里渊光学相关域应变和温度分布鉴别。该方法在原高频率调制的激光源上增加一个低频率调制，用于布里渊动态光栅的分布式产生和检测。该方案可以抑制高频调制引起的相关峰，从而在保持高空间分辨率的同时，延长测量范围。在本实验中，测量范围从~ 5米增加到34米，空间分辨率保持为10厘米。
A scheme of dual frequency modulations are proposed for one-laser Brillouin optical correlation-domain distributed discrimination of strain and temperature. A lower frequency modulation is additionally applied to the laser source, which is originally modulated by a higher one for distributed generation and detection of Brillouin dynamic grating. This scheme can suppress the unwanted correlation peaks due to the higher frequency modulation so as to elongate the measurement range with keeping the high spatial resolution. In this experiment, the measurement range is increased from ~ 5 to 34 m with the spatial resolution maintained to be 10 cm.
