Abstract

a. Installation optique et électronique pour lire des informations se trouvant sur un support d'informations. b. Installation caractérisée en ce que sur le support d'informations sont disposées au moins deux pistes comportant une répartition de champ clair-obscur avec des têtes de lecture disposées de façon correspondante, tandis que pour saisir le modèle réel de chiffres binaires ainsi que pour l'autocadencement, la disposition de la répartition de champ clair-obscur sur au moins l'une des pistes, est attaquée de façon telle que pour chaque chiffre binaire d'information devant être lu, une modification simultanée de la répartition de champ clair-obscur est prévue en ce qui concerne l'étendue de cadencement. c. L'invention peut notamment être appliquée au contrôle des pièces d'identité.at. Optical and electronic installation for reading information found on an information medium. b. Installation characterized in that on the information carrier are arranged at least two tracks having a chiaroscuro field distribution with correspondingly arranged read heads, while for entering the actual pattern of binary digits as well as for the self-timing, the arrangement of the chiaroscuro field distribution on at least one of the tracks, is attacked in such a way that for each binary digit of information to be read, a simultaneous modification of the chiaroscuro field distribution is provided with regard to the timing range. vs. The invention can in particular be applied to the control of identity documents.
