摘要
阐述了基于布里渊散射分布式光纤传感技术的原理和分类,简要介绍了BOTDR(布里渊光时域反射)、BOTDA(布里渊光时域分析)、BOCDA(布里渊光相干域分析技术)、BOCDR(布里渊光相干域反射技术)、BOFDA(布里渊光频域分析技术)原理及应用进展。
This paper illustrate to the sensing principle and classification of Brillouin scattering distributed optical fiber sensor.Principles of the Brillouin scattering distributed optic fiber sensor as well as of BOTDR sensor, BOTDA sensor, BOCDA sensor, BOCDR sensor, BOFDA sensor that based on OTDR are illustrated.
