摘要
从光时域反射仪(OTDR)的原理入手,介绍了分布式光纤传感器的当前进展及发展趋势,主要包括基于瑞丽后向散射的传感器,基于布里渊散射的分布式光纤传感器,基于拉曼后向散射的温度传感器,以及偏振模耦合分布式光纤传感器。对其特点及存在的问题进行了比较,并指出了未来发展方向。
The current development of distributed fiber sensors is introduced based on the principles of OTDR, including Brillouin scattering OTDR, Raman scattering OTDR, Relei scattering OTDR as well as polarization mode coupling distributed fiber sensors. The advantages and disadvantages are summarized, and at same time, the fea- tures and future development trend are outlined.
