Spr interferometer

摘要

The present invention concerns an interferometer comprising: an optical body adapted in operation to mount a measurement area comprising a film which is capable of acting as a two dimensional environment for surface plasmons and an adjacent reference area; an optical beam generation means for irradiating the reference and measurement areas with radiation capable of generating surface plasmon resonance; optical means for combining radiation reflected from the reference and measurement areas, and pixelated detection means for generating data representing two dimensional images of the combined radiation beams.
