    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 present invention relates to an imaging system for analysing fluorescent molecules in a sample (2), including a confocal microscope device (1) comprising a support (3) in contact with at least a portion of said sample (2). In said system, the support surface (3) in contact with the sample (2) is functionalised so as to reduce the observation volume (6) of the microscope on the surface in the axial direction. The present invention also relates to various uses of such a system as well as to a method for analysing fluorescent molecules in a sample, said method being implemented by such a system.
