CA 2238809

A method and apparatus for verifying the composition of a moving product employs a source of near infra-red radiation for illuminating the product. Means for receiving data relating to the location of the product and using said data to receive radiation from the source reflected from the located product and a spectrometer for receiving the radiation from the radiation receiving means and providing an output corresponding to the intensity of the received radiation at a number of different wavelengths are provided. Also provided is means for determining whether or not the product is within predetermined integrity criteria on the basis of the spectrometer output.

Méthode et appareil permettant de vérifier la composition d'un produit en mouvement. L'appareil utilise une source de rayonnement à proche infrarouge afin d'illuminer le produit. Un dispositif reçoit les données concernant l'emplacement du produit et utilise ces données pour recevoir le rayonnement émis par la source et réfléchi sur le produit; un spectromètre capte le rayonnement provenant du dispositif de réception de rayonnements et produit des données de sortie correspondant à l'intensité des rayonnements reçus à un certain nombre de longueurs d'onde différentes. L'appareil comprend également un dispositif permettant de déterminer si le produit correspond à des critères d'intégrité prédéterminés à partir des données de sortie produites par le spectromètre.
