Abstract

Des codes à barres, imprimés ou appliqués d'une autre manière sur un objet, sont lus et décodés par focalisation de la lumière réfléchie par le code au moyen d'un objectif sur un transducteur photosensible. Les signaux électriques produits par le transducteur sont convertis d un format de code ternaire en un format de code binaire. Le code ternaire utilise des barres et des demi-barres formées de segments disposés dans un ou plusieurs de quatre quadrants pour représenter un nombre décimal équivalent. Ce code ternaire est appliqué à un convertisseur où une logique convertit les signaux ternaires en signaux binaires équivalents qui sont alors traduits d'un format série en un format parallèle en vue de leur traitement ultérieur par des processeurs de code binaire classiques. Application particulière à la lecture de codes à barres sur des mobiles se déplaçant rapidement tels que le matériel roulant des chemins de fer.
