An imaging apparatus for imaging a sample () comprises an array of electronically addressable pixels () wherein each pixel is arranged to support a surface plasmon resonance therein to generate an evanescent electromagnetic field. This field extends transversely from the pixel so as to be salient from the array at a first side of the array for illuminating the sample at said first side. A light source () is arranged to illuminate the array with excitation light therewith to generate said surface plasmon resonance. An optical detector (A,B,C) is arranged at a second side of the array which is opposite to said first side of the array for detecting optical radiation returned from the array in response to illumination of the array by said excitation light. A processing unit () is arranged to associate the detected optical radiation with the address of the pixel or pixels within the array at which the surface plasmon resonance was generated.

Addressable plasmonic arrays

An imaging apparatus () for imaging a sample () comprising an array of electronically addressable pixels () wherein each pixel is arranged to support a surface plasmon resonance thereinto generate an evanescent electromagnetic field () which extends transversely from the pixel so as to be salient from plane of the array for illuminating the sample (). An optical detector () is arranged for detecting optical radiation () scattered from the evanescent electromagnetic field () by the sample (). A processing unit () arranged to associate the detected optical radiation () with the address of the pixel or pixels within the array at which the surface plasmon resonance was generated.
