Abstract
An interferometric method was used for the first time to detect, under surface-plasmon resonance conditions, phase changes in a reflected be am caused by changes in the refractive index of the medium being diagn osed. The threshold of the sensitivity to changes in the refractive in dex was estimated to be 4 x 10(-8). The proposed interferometer can be used successfully in bio and chemical-sensor systems.
