摘　　要：设计了一种新型的基于四棱镜结构的分布式表面等离子体共振(SPR)传感器,用数值模拟法讨论了金属膜种类、调制层厚度和折射率、棱镜结构参数对其性能的影响,得到了有用的结论。最后,提出了SPR分布式传感器的评价因子,为今后的分布式SPR传感器设计、制作和性能评价提供了有益的参考。A novel distributed SPR sensor based on four-prism was designed. Type ofmental layer, thickness of tuning layer and it＇s refraction index have close relationship with the property of distributed SPR sensors, and all these were discussed with the method of numerical simulation, some useful results were obtained. At last, evaluation factor of distributed SPR sensor was presented, which will be helpful to the design, fabrication and evaluation of distributed SPR sensor.
