基于F-P干涉的两段式光纤传感器
wo-segment fiber optic sensor based on F-P interference
F-P 型传感器由于结构简单，无需耦合器，体积小，封装容易等优点获得了广泛关注。通过熔接两段不同折射率光纤，并将传感光纤包层去掉浸泡在待测液体中，构成了F-P腔折射率传感器。在仿真中，传感器的最小分辨率为3.0135e-4，并且光纤器件长度较小，在仿真中传感光纤长度仅为15um，尺寸远小于其他F-P干涉仪，并且对于传感光纤长度精度要求很低，便于制造。
F-P sensors have attracted wide attention due to their simple structure, no coupler, small size, and easy packaging. An F-P cavity refractive index sensor is formed by fusing two sections of fibers with different refractive indices and removing the cladding of the sensing fiber in the liquid to be measured. In the simulation, the minimum resolution of the sensor is 3.0135e-4, and the length of the fiber optic device is small. In the simulation, the length of the sensing fiber is only 15um, which is much smaller than other FP interferometers. It has very low accuracy requirements for sensing fiber length and easy to manufacture.
