Abstract

Simulation and experimental results have shown that the combination of two kinds of codes to modulate phase-shift pulse Brillouin optical time domain analysis (PSP-BOTDA) pump pulse for distributed strain measurement provides higher SNR than that of using only one code system, and better spatial resolution than dual Golay codes PSP-BOTDA. In preliminary experiments, 10cm spatial resolution measurement was demonstrated.

结合walsh码和Golay码调制相移脉冲BOTDA传感器的泵浦光

仿真和实验结果表明，两种编码组合调制相移脉冲布里布鲁因光时域分析(PSP-BOTDA)泵浦光脉冲用于分布式应变测量，比仅使用一种编码系统具有更高的信噪比，比双Golay编码PSP-BOTDA具有更好的空间分辨率。在初步实验中，进行了10cm空间分辨率测量。
