    摘要: The invention concerns an evanescent wave microspectrometer comprising: a planar diopter (D) separating two transparent media, an optical sensor (30) comprising a pixel array, and disposed in the second transparent medium (M2), and an interference device ((10, F1); (11, F1_1, F1_2)) disposed such that at least a part of said interference device is in contact with evanescent waves generated at the surface of the diopter. It is essentially characterised in that it also comprises: a memory storing a map (40) comprising a set of set of data grids (41, 42, 43) comprising the optical response of said sensor (30) for a set of quasi-monochromatic wavelengths of a calibration light source, and a calculator (50) configured to determine the spectrum (ψ) of a test light source configured to generate evanescent waves at the surface of said diopter (D), on the basis of said map (40) and the optical response of said sensor (30).

    摘要: The invention concerns an electronic method for extracting the amplitude Es and the phase φε of an electrical signal in synchronous detection, the signal containing a modulated part lmod of the form lmod ∝ Es f(t)*cos(ϕs -ϕR(t)),, in which ϕR(t) and f(t) are two known temporal modulation functions. The method comprises the following steps: -multiplying the signal with two reference signals C(t) and S(t) constructed from ϕR(t) and f(t); -integrating the resulting signals during a period tint; -determining the amplitude and the phase of said signal from quantities X and Y resulting from the preceding integration operations. The method is characterised in that: -said signal is multiplied by two orthogonal signals C and S that can be decomposed on the same set of frequencies as those present in lmod; f(t) is periodic or constant during integration period tint; ϕR(t) is periodic during integration period tint; and X and Y are linked to Es*cos(ϕs) and Es*sin(ϕs) by two calculated proportionality coefficients. The invention concerns the interferometric assemblies for implementing the above method, and the execution of same using analogue components, circuit boards or software solutions.

    摘要: 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).
