We present a promising optical system and technique for detection, imaging, and visualization of minimal changes, of the order of 10[sup -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. © 2000 American Institute of Physics. [ABSTRACT FROM AUTHOR] |
