Title (EN) DETECTION OF INDICATIONS OF PSYCHOACTIVE COMPONENTS IN A LIQUID
(FR) DÉTECTION DE SIGNES DE COMPOSANTS PSYCHOACTIFS DANS UN LIQUIDE
Abstract:
(EN) A method of contactless detection of indications of psychoactive components in a liquid (6) is disclosed and an apparatus therefor, the method comprising the steps of emitting substantially monochromatic light at least at two different wavelengths (La, Lb) and detecting the reflection in a free surface (12) of said liquid (6) by means of a photo detector (5), analysing an output signal from the photo detector (5) to identify output parts caused by light emitted from the first (3a) and second emitter (3b), respectively, and determine whether the liquid (6) contains at least one psychoactive component.
(FR) L'invention concerne un procédé de détection sans contact de signes de composants psychoactifs dans un liquide (6) ainsi qu'un appareil associé. Le procédé selon l'invention comprend les étapes suivantes : l'émission d'une lumière sensiblement monochromatique à au moins deux longueurs d'onde différentes (La, Lb) et la détection de la réflexion sur une surface libre (12) dudit liquide (6) au moyen d'un photodétecteur (5), l'analyse d'un signal de sortie du photodétecteur (5) pour identifier les éléments de sortie engendrés par la lumière émise respectivement par le premier émetteur (3a) et le second émetteur (3b) et pour déterminer si le liquide (6) contient au moins un composant psychoactif.
