基于光学共振技术的折射率(RI)传感器正受到高度重视，因为需要为许多应用开发简单、低成本、高通量的检测技术。虽然大多数已报道的RI传感器的传感机制相似，但其结构因技术而异。希望具有用于比较各种RI感测技术的统一机制，但是到目前为止，关于如何量化感测性能存在一定程度的差异。在这里，我们对谐振式RI传感器的检测极限进行了严格的定义，它考虑了影响检测性能的所有参数。我们的工作将为量化和比较基于光学共振的RI传感器的性能提供一种标准方法。此外，还将为RI传感器的性能改进提供设计策略。(C)2008年美国光学学会。
Refractive index ( RI) sensors based on optical resonance techniques are receiving a high degree of attention because of the need to develop simple, low-cost, high-throughput detection technologies for a number of applications. While the sensing mechanism of most of the reported RI sensors is similar, the construction is quite different from technique to technique. It is desirable to have a uniform mechanism for comparing the various RI sensing techniques, but to date there exists a degree of variation as to how the sensing performance is quantified. Here we set forth a rigorous definition for the detection limit of resonant RI sensors that accounts for all parameters that affect the detection performance. Our work will enable a standard approach for quantifying and comparing the performance of optical resonance-based RI sensors. Additionally, it will lead to design strategies for performance improvement of RI sensors. (c) 2008 Optical Society of America.
