We have experimentally developed a hybrid-structure multi-channel all-fiber current sensor with ordinary silica fiber using fiber loop architecture. According to the rationale of time division multiplexing, the sensor combines parallel and serial structures. The purpose of the hybrid-structure multi-channel all-fiber current sensor is to get more information from the different measured points simultaneously. In addition, the hybrid-structure fiber current sensor exhibited a good linear response for each channel. A three-channel experiment was performed in the study and showed that the system could detect different current positions. Each channel could individually detect the current and needed a separate calibration system. Furthermore, the three channels will not affect each other.
我们通过实验利用光纤环架构开发了一种采用普通石英光纤的混合结构多通道全光纤电流传感器。根据时分复用原理，该传感器结合了并行和串行结构。混合结构多通道全光纤电流传感器的目的是同时从不同测量点获取更多信息。此外，混合结构光纤电流传感器对每个通道都表现出良好的线性响应。在该研究中进行了三通道实验，结果表明该系统能够检测不同的电流位置。每个通道都可以单独检测电流，并且需要一个单独的校准系统。此外，这三个通道不会相互影响。
