The present disclosure provides a portable device and method for controlling an alcoholic beverage through an at least partially transparent container. The method includes acquiring a fluorescence spectrum of the beverage through a wall of the container, normalizing a profile of a measured spectrum according to the maximum intensity of a reference spectrum, calculating a resemblance factor between the measured spectrum and the reference spectrum, and determining if the beverage is genuine according to the obtained value of the resemblance factor.

Portable device for controlling an alcoholic beverage through a container, a system and a method associated thereto

The present disclosure provides a portable device for controlling an alcoholic beverage that includes a single light source emitting a monochromatic excitation light beam of a wavelength between 350 and 650 nanometers, a beam splitter to reflect the light beam, a focus and collection lens, and a positioning device to orient the light beam along a direction substantially normal to an outer surface of the container. The positioning device positions the outer surface of the container at a predetermined distance from the focus lens. The device includes a filtering device for filtering fluorescence radiation captured by the focus lens to eliminate wavelengths shorter than or equal to the wavelength of the light beam. A spectrometer module produces a signal corresponding to the measured spectrum of the fluorescence radiation and an analysis module compares the measured spectrum to a reference spectrum.
