摘要

我们报告了使用超高分辨率可调谐光子计数OTDR远程表征Bragg光栅的可能性。可实现的2.8 cm分辨率以及该技术的可调性允许测定由光栅引起的色散及其在光纤内的长度。我们相信这种表征技术可以用于不同布拉格光栅光纤传感器的远程监测。

Remote fiber Bragg grating-based sensor characterization with ultra-high-resolution tunable photon counting OTDR

We report on the possibility of remotely characterizing Bragg gratings using an ultra-high-resolution tunable photon-counting OTDR. The achievable 2.8 cm resolution as well as the tunability of the technique permit the determination of the dispersion induced by the grating and its length inside the fiber. We believe that this characterization technique can be employed in long distance monitoring for different Bragg-grating fiber sensors.
