我们演示了基于斜率辅助（SA-）布里渊光相关域反射计（BOCDR）使用高损耗塑料光纤（POF）的高速分布式传感。与石英光纤的情况不同，由于传输功率沿着POF逐渐减小，应变和温度灵敏度被发现依赖于传感位置。这种独特的影响进行了研究，理论和实验，然后一个正确的POF为基础的分布式测量是可行的，通过补偿这种影响。
We demonstrate high-speed distributed sensing based on slope-assisted (SA-) Brillouin optical correlation-domain reflectometry (BOCDR) using high-loss plastic optical fibers (POFs). Unlike the case of silica fibers, due to the gradual reduction in the transmitted power along the POF, the strain and temperature sensitivities are found to depend on sensing position. This unique effect is investigated both theoretically and experimentally, and then a correct POF-based distributed measurement is shown to be feasible by compensating this effect.
