多路光纤传感器通常用于对多个离散位置进行测量的场合,目前,基于纤内(in-fibre)布拉格(Bragg)光栅的多通道光纤传感器阵列的研究正在快速进入实用阶段。根据目前的研究成果,研究人员用紫外光在光纤的轴线方向产生一个周期性变化的折射率,即可以制作布拉格光栅。多路转换将会在多个方面得到应用。 Multi-channel fiber optic sensors are often used to measure multiple discrete locations. Currently, multi-channel fiber sensor arrays based on in-fiber Bragg gratings are rapidly moving into practical use. According to the current research results, researchers can produce Bragg gratings by using ultraviolet light to produce a periodic index of refraction in the axial direction of the optical fiber. Multiplexing will be applied in many ways.
