L'objectif de l'invention est de créer un détecteur qui puisse présenter une sensibilité et une précision de détection particulièrement élevées lors de la vérification de l'authenticité du document de valeur (4). A cet effet, l'émetteur (6) est conçu pour produire un signal de balayage présentant une longueur d'onde d'excitation comprise entre 940 nm et 990 n, et le récepteur de rayonnement (12) est conçu pour détecter un signal de réponse présentant une longueur d'onde de réponse d'environ 800 +/- 10 nm. L'invention concerne également un document de valeur (4) comportant au moins un élément de sécurité (2) conçu pour permettre une reconnaissance d'authenticité au moyen du détecteur (1) selon l'invention. Ce document de valeur (4) présente, dans une zone repère (14), une couche repère (18) qui comporte des pigments antistokes (20) luminescents, déposés sur un substrat (16) et qui est recouverte par une couche de recouvrement (22) perméable aux rayons infrarouges proches.
