摘要： L'invention se rapporte à procédé de contrôle d'une boisson alcoolisée à travers un contenant au moins partiellement transparent, le procédé comportant les étapes consistant à :
- acquérir (80) un spectre de fluorescence de la boisson à travers la paroi du contenant ;
- normaliser le profil du spectre mesuré par rapport au maximum d'intensité d'un spectre de référence ;
- calculer un facteur de ressemblance entre le spectre mesuré et le spectre de référence ;
- déterminer (86), en fonction de la valeur du facteur de ressemblance obtenue si la boisson est authentique.

摘要： The invention relates in particular to a portable device (1) for testing an alcoholic beverage in an at least partially transparent container (2), comprising a single light source (32) that emits a monochromatic excitation light beam having a wavelength of between 350 and 650 nanometres; a beam splitter (36) oriented at 45° relative to the emission direction of the light source (32) in order to reflect the excitation light beam; a focussing and collecting lens (40); a positioning device (12) making it possible to orient the light beam coming from the light source (32) in a direction substantially normal to the outer surface of the container (2), the positioning device (12) also making it possible to position the outer surface of the container at a predetermined distance from the focussing lens, the predetermined distance between the focussing lens and the container being selected so that the light beam is focussed in the beverage, at a distance of less than 1 millimetre, preferably less than 500 micrometres, from the wall of the container, the positioning device (12) comprising a through-opening for the passage of the light beam coming from the light source; a filtering device (44) for filtering the fluorescent radiation captured by the focussing lens (40) and transmitted by the beam splitter (36) so as to eliminate wavelengths which are less than or equal to the wavelength of the light beam emitted by the light source; a spectrometry module (50) for producing a signal corresponding to the measured spectrum of the fluorescent radiation of the beverage; and an analysis module (62) for comparing the measured spectrum with a reference spectrum.
