Abstract

Différents exemples de réalisation de l'invention concernent et un dispositif (100) servant à déterminer une information prédéfinie d'un objet (112) le long d'une voie de transport (110). Le dispositif possède (100) : la voie de transport (110), qui comporte au moins une position de départ (102) et au moins une position finale (104) et qui est conçue pour transporter l'objet (112) de l'au moins une position de départ (102) à l'au moins une position finale (104) ; l'objet (130) comprenant un dispositif d'émission (120) optiquement actif, lequel possède au moins un composant émetteur de lumière (114) et un dispositif de commande (116) qui est conçu pour commander l'au moins un composant émetteur de lumière (114) de telle sorte qu'il émet une séquence prédéfinie d'impulsions lumineuses (124) ; et un dispositif de réception (140) optiquement actif. Le dispositif de réception (140) optiquement actif possède au moins un photodétecteur (132) et un dispositif de détermination (134). L'au moins un photodétecteur (132) est conçu pour détecter la séquence d'impulsions lumineuses (124) de la lumière pouvant être émise par le composant émetteur de lumière (114) au niveau d'au moins une position entre l'au moins une position de départ (102) et l'au moins une position finale (104) de la voie de transport (110) et la convertir en un signal (136). Le dispositif de détermination (134) est conçu pour déterminer l'information prédéfinie à partir du signal (136) du photodétecteur (132).
