摘　　要：光纤表面等离子体共振(surface plasmon resonance,SPR)传感器具有检测灵敏度高、响应速度快和实时在线监测等优势,在生物、化学、医学等领域应用广泛。然而,传统单通道光纤SPR传感器仅有一个传感区,只能进行单点测量,这极大地限制了其进一步的发展和应用。多通道光纤SPR传感器由于检测通量大、检测物质多、可实现温度补偿、剔除各种非特异性响应等特性,可以很好地弥补传统单通道光纤SPR传感器的不足。研究多通道光纤SPR传感器对提高传统单通道光纤SPR传感器的检测灵敏度、检测精度和扩大其应用领域具有重要意义。本文从光纤SPR传感器原理出发,介绍了近年来多通道光纤SPR传感器的研究进展,对未来多通道光纤SPR传感器的研究方向进行了展望。新结构、高性能、多应用的多通道光纤SPR传感器是未来多通道光纤SPR传感器的重要发展方向,而新材料、新工艺的融入必将使多通道光纤SPR传感器的发展与应用迈上新的台阶。Fiber optic surface plasmon resonance(SPR)sensor has the advantages of high detection sensitivity,fast response speed and real-time online monitoring,and has a good application prospect in biology,chemistry,medicine and other fields.However,the traditional single-channel fiber SPR sensor has only one sensing area and can only perform one single-point measurement,which greatly limits its further development and application.The multi-channel fiber SPR sensor can make up for the shortcomings of traditional single-channel fiber SPR sensor because of its large detection flux,many detection substances,realization of temperature compensation,and elimination of various non-specific responses.The research of multi-channel fiber SPR sensor is of great significance to improve the detection sensitivity and detection accuracy of traditional single-channel fiber SPR sensor and expand its application fields.First of all,the principle of fiber SPR sensor is introduced.Then,the research progress of multi-channel fiber SPR sensor in recent years is presented.At the end,the future research direction of multi-channel fiber SPR sensor is prospected.Multi-channel fiber SPR sensor with new structure,high performance and multi-application is an important development direction of multi-channel fiber SPR sensor in the future,and the integration of new materials and new processes will surely bring the development and application of multi-channel fiber SPR sensor to a new level.
