我们提出了一种有前途的光学系统和技术，用于检测、成像和可视化近场折射率 10(-6) 量级的微小变化。该系统基于与样品接触的导电层中激发的表面等离子体的相位成像。此处显示的该技术足够灵敏，可以对氮气气氛中氦气和氩气的流动进行成像。建议将其应用于生物和化学研究。 (C) 2000 年美国物理研究所。 [S0003-6951(00)02313-5]。
We present a promising optical system and technique for detection, imaging, and visualization of minimal changes, of the order of 10(-6) in refractive index, in the near field. The system is based on phase imaging of excited surface plasmons in a conducting layer in contact with a sample. This technique is shown here to be sensitive enough to image the flow of helium and argon gas in a nitrogen atmosphere. Its application to biological and chemical research is suggested.
