    Abstract: According to one aspect, the invention relates to a device (100) for remote polarimetric characterisation of a sample (S). It comprises a source (10) for emitting at least one incident light wave at at least one first wavelength (λ
    Ε ); a monomode optical fibre (30) in which the incident light wave is intended to propagate; a polarisation state generator (PSG) arranged on the proximal side of the optical fibre; a reflector (40) intended to be arranged on the distal side of the optical fibre; a polarisation state analyser (PSA) arranged on the proximal side of the optical fibre and allowing, for each probe state of the incident wave generated by the polarisation state generator, the polarisation of the light wave obtained after propagation of the incident wave in the optical fibre (30), reflection from the distal side of the optical fibre and reverse propagation in the optical fibre (30), to be analysed. Processing means (70) make it possible to determine, from a first polarimetric characterisation of the optical fibre, a Mueller matrix (M
    F ) associated with the optical fibre, and, from a second polarimetric characterisation of the assembly comprising the optical fibre and the sample, a Mueller matrix (Μ
    T ) associated with said assembly. The Mueller matrix (Μ
    o ) associated with the sample is determined from the Mueller matrices associated with the optical fibre and the assembly comprising the optical fibre and the sample, respectively.

    Abstract: An optical sensing device is provided, including a first polariser, a second polariser, wherein the first polariser and the second polariser have respective transmission axes aligned in orthogonal directions, an SPR sensor arrangement including an SPR sensing surface, the SPR sensor arrangement arranged to receive an incident light beam passed through a polariser to be reflected at the SPR sensing surface and transmitted through a second polariser to provide a transmitted light beam, a detector arrangement configured to detect the transmitted light beam, the transmitted light beam including a sensing signal and a reference signal, and a processor electrically coupled to the detector arrangement, the processor configured to perform a subtraction operation between the sensing signal and the reference signal. The optical sensing is based on a differential measurement scheme. The subtraction between the sensing signal and the reference signal cancels the common path noise and enhances the sensor resolution.
