Abstract
UNE CAMERA DE TELEVISION POURVUE D'UN ETAGE DE REGLAGE ET D'UN ETAGE DE MISE AU POINT POUR LE REGLAGE DU COURANT DE FAISCEAU D'UN FAISCEAU ELECTRONIQUE DANS UN TUBE DE CAPTATION. LE SIGNAL D'IMAGE CREE PAR LE TUBE DE CAPTATION EST ADAPTE AU MOYEN D'UN AMPLIFICATEUR DE SIGNAUX D'IMAGE PRATIQUEMENT A VIDEO-FREQUENCE DE MANIERE A DELIVRER LE SIGNAL D'IMAGE DANS PRATIQUEMENT TOUTE LA GAMME D'AMPLITUDES DE LA PRODUCTION DU SIGNAL D'IMAGE PAR LE TUBE DE CAPTATION, CE SIGNAL ETANT DELIVRE VIA UN CONDENSATEUR DE COUPLAGE A TITRE DE TENSION DE REGLAGE SUPERPOSEE A LA TENSION DE MISE AU POINT POUR L'ELECTRODE DE REGLAGE DU TUBE DE CAPTATION. ON OBTIENT AINSI UN REGLAGE DE COURANT DE FAISCEAU STABLE SANS AUCUNE OSCILLATION. APPLICATION AUX CAMERAS DE TELEVISION.
