摘要

光纤布拉格光栅(FBG)具有许多特性，使其在传感应用中非常有用。在这项工作中，我们展示了一种基于双光栅干涉仪串行阵列的多路复用传感器。该传感器采用低反射布拉格光栅，易于制造。通过实验和计算机仿真对波分频复用组合进行了测试。该方法在许多基于布拉格光栅的光纤传感器的多路复用中具有很大的潜力。

Multiplexed twin Bragg grating interferometric sensor

Optical fiber Bragg gratings (FBG) have numerous features making them very useful for sensing applications. In this work, we demonstrate a multiplexed sensor based on a serial array of twin-grating interferometers. The sensor employs low reflective Bragg gratings and is easy to manufacture. The combination of wavelength- and frequency-division multiplexing was tested experimentally and using a computer simulation. The approach has a great potential in multiplexing of many Bragg grating-based fiber-optic sensors.
