摘要
布里渊光时域反射计(BOTDR)在大型民用工程方面具有广泛的应用前景。本文通过对几种检测方式进行分析与比较,最终为BOTDR选定了基于光相干检测和扰偏消偏振衰落技术的光信号检测技术方案。
BOTDR had a good application prospect in civil engineering projects. This thesis had analyzed and compared several detection methods of BOTDR,and finally chose the technical proposal based on optical coherent detection and polarization-induced fading of scrambling to detect BOTDR optical signal.
