摘　　要：文中首先介绍了布里渊分布式光纤传感技术的原理。在此基础上分析了基于布里渊传感器上的光纤应变增敏技术,并制作了应变增敏光纤。通过对增敏光纤进行拉伸实验,得出实验数据的标准差大多都在20με以下,证明了增敏的有效性。This article introduced the principle of the distributed optic fiber sensors based on Brillouin scattering.Improving sensitivity technology of sensors based on Brillouin to strain is analyzed and improving sensitivity of fibers to strain was done.In the tensile test of sensitivity fibers,standard deviations on experimental data are mostly under 20 με and it proves the efficiency of their improving sensitivity.
