光纤布拉格光栅是近几年来光纤传感领域的研究热点,而基于它的分复用技术则是实现多点测量和准分布式传感的关键技术之一。纵观近十年该领域的研究成果,分类讲述了各种复用技术在FBG传感方面的应用,包括波分复用、时分复用、频分复用和其他复用技术的工作原理、特点和性能,最后加以比较和讨论。

Fiber Bragg grating is the most important subject in optical fiber sensing, and the multiplexing/demulti－plexing technology based on FBG sensors is one of the key technologies of multi-point measurement and pseudo-distribution sensing. The applications of various multiplex technology in FBG sensing, including the principles of op－eration, characteristics and functions of WDM, TDM, FDM etc are described and compared on surveying the research achievements in this field for the last ten years.
