Abstract
Examinations of biological, biochemical, and chemical characteristics of media, mainly of biologic origin, or media that are in contact with biological objects whose living is influenced by the media characteristics. One excites surface plasmon polaritons on a metal layer covered with a material sensitive to the examined characteristics of a medium, produces an interference with a beam of radiation reflected under these conditions and a reference beam, records parameters of a spatial intensity distribution in the resulting interference pattern, and judges the examined characteristics on the basis of the recorded parameters. The proposed method and apparatus ensure the technical result that consists in upgrading of sensitivity and resolution of measurements, at least, by two orders.
