Summary:A plasmonic sensor device includes a light source, configured to generate coherent light; a metallic film, at least partially covered on one side by analyte molecules; at least one micromirror that is rotatable about at least one axis of rotation, which is positioned and developed in such a way that the coherent light is able to be guided at an angle of incidence to one side of the metallic film, the angle of incidence being variable by the rotating of the at least one micromirror about the at least one axis of rotation; and a detector configured to determine the intensity of the light guided onto the metallic film and reflected again from there, as a function of the angle of incidence, the coherent light generated by the light source being in such a state that surface plasmons are excitable in the metallic film depending on the angle of incidence.
