Abstract (en)

[origin: WO2014195655A1] The invention relates to an interferometric device including: a separator (20), for separating a collimated beam (F0) into first (F1) and second (F2) incident beams; at least one transducer (13); and a transparent optical system (10), including at least three planar dioptres (D1, D2, D3). The invention is characterised essentially in that the transducer (13) is based on plasmon resonance and in contact with the dioptre (D1); the dioptre (D2) has a network of nanostructures; the optical system (10) and the separator (20) being configured such that the beam (F1) and the beam (F2) undergo total internal reflection on the dioptre (D1) and on the dioptre (D3), respectively, prior to interfering on the dioptre (D2) by total internal reflection and to forming an interferogram in which the central fringe is located at a convergence point (ZOPD).
