Claim:
1. An interferometric device comprising: a splitter configured to split a collimated incident light beam into a first incident beam and a second incident beam; a transparent optical block comprising a set of at least three plane faces, and at least one transducer configured to carry out a transduction based on surface plasmon resonance and in contact with a first face; wherein a second face carries a network of nanostructures; the optical block and the splitter being configured so that the first incident beam undergoes at least one total internal reflection on the first face and the second incident beam undergoes at least one total internal reflection on a third face before they interfere on the second face under total internal reflection; the interferometric device further comprising a computer configured to simultaneously compute the spectral distribution of the amplitude and the relative phase of the incident light beam that has interacted with at least one transducer by the first incident beam or by the second incident beam, and wherein the first face supports a plurality of transduction zones, each transduction zone comprising an individual transducer.
