SPR Technology in Detecting the Imaginary Part of Refractive Index of Absorptive Medium
传感器 表面等离子体共振 吸收介质 折射率虚部 sensors surface plasmon resonance absorptive sample imaginary part of the refractive index
摘要
该文数值模拟了表面等离子体共振(SPR)技术在吸收介质折射率虚部变化检测方面的应用。以菲涅耳多层膜反射理论为基础研究了强度调制、相位调制和角度调制三种检测方法。研究结果表明，角度调制方式拥有较高的检测分辨率（1×10-6 RIU，RIU为折射率单位）和较宽的线性测量范围（大于0.01 RIU），是一种较好的检测折射率虚部变化的方法。
Abstract
In this paper, the surface plasmon resonance (SPR) technology for measuring the absorptive sample′s imaginary part of the refractive index is studied via numerical simulations. By using the Fresnel equation, intensity, phase, and angle modulations are analyzed. The results show that, the angle interrogation has the highest resolution (1×10-6 RIU) and the widest linear measurement range. So the angular modulation is a good choice for measuring the absorptive sample′s imaginary part of the refractive index.
