摘要

我们提出了一种利用全氟渐变折射率聚合物光纤（POFs）提高布里渊光相关域反射计（BOCDR）空间分辨率的策略。通过利用调制幅度和传感光纤长度之间的关系，我们实现了大约4.8厘米的理论空间分辨率，超越了以前的限制。这是通过减少相对于测量范围的光纤长度来增加超过常规限制的调制幅度来实现的。我们通过初步实验验证了我们的方法，并演示了具有高空间分辨率的分布式温度传感，成功地检测了短至7.0 cm的冷却部分。

High-resolution distributed temperature sensing along polymer optical fiber using Brillouin optical correlation-domain reflectometry

We present a strategy to enhance spatial resolution in Brillouin optical correlation-domain reflectometry (BOCDR) using perfluorinated graded-index polymer optical fibers (POFs). By exploiting the relationship between modulation amplitude and sensing fiber length, we achieve a theoretical spatial resolution of approximately 4.8 cm, surpassing previous limitations. This is accomplished by increasing the modulation amplitude beyond the conventional limit through reduction of the fiber length relative to the measurement range. We validate our approach with preliminary experiments and demonstrate distributed temperature sensing with high spatial resolution, successfully detecting a cooled section as short as 7.0 cm.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
