Abstract

L'invention concerne un appareil d'examen de récipients, en particulier d'examen sans contact, pour la détection d'impuretés, en particulier dans le cas de bouteilles, de préférence de bouteilles de RefPET, comprenant un dispositif d'éclairage pour éclairer un récipient avec une lumière d'au moins une longueur d'onde, un dispositif de capture optique conçu pour capter au moins une image multispectrale du récipient, et un dispositif d'analyse connecté au dispositif de capture optique et conçu pour : déterminer au moins une partie d'un spectre de fréquence, qui représente un fluide contenu dans le récipient, d'au moins une section, de préférence une pluralité de sections, d'au moins une image multispectrale du récipient ; comparer ladite au moins une partie déterminée du spectre de fréquence avec un ou plusieurs spectres de fréquence pouvant être prédéfinis d'un ou plusieurs fluides de référence ; fournir un résultat de comparaison ; et déterminer si le fluide contenu dans le récipient comprend une impureté, sur la base du résultat de la comparaison.
