Abstract

L'invention divulgue un dispositif pour déterminer l'existence et la position d'un objet apparaissant dans d'une zone prédéfinie. Le dispositif comporte un ensemble de photo-émetteurs (1) et un ensemble de photo-détecteurs (2) placés à l'opposé de l'ensemble de photo-émetteurs de telle sorte que le photo-émetteur et le photo-détecteur de chaque paire de photo-émetteur/détecteur se font face et sont opposées l'un à l'autre ; le photo-émetteur (1) et le photo-détecteur (2) sont placés sur le pourtour de la zone prédéfinie de telle sorte que les faisceaux de lumière envoyés des photo-émetteurs (1) aux photo-détecteurs (2) forment une grille de coordonnées. Le dispositif comporte également une unité de traitement (40) pour traiter les signaux de sortie des photo-détecteurs (2) et déterminer ainsi les coordonnées de l'objet lorsque l'objet apparaît dans la zone prédéfinie.
