Title
(EN) ELECTROGRAPHIC PROCESS FOR GENERATING AN ELECTRICAL IMAGE SIGNAL
(FR) PROCEDE ELECTROGRAPHIQUE DE PRODUCTION D'UN SIGNAL D'IMAGE ELECTRIQUE
Abstract
(EN) An electrical image signal is produced by an electrographic process including the steps of forming a differential voltage pattern; developing the voltage pattern with a luminescent toner; exciting the developed image to emit radiation; and photoelectrically detecting the emitted radiation to produce an electrical image signal.
(FR) Un signal d'image électrique est produit par un procédé électrographique consistant à former une image de tension différentielle, à développer l'image de tension avec un toner luminescent, à exciter l'image développée pour produire l'émission d'un rayonnement et à détecter photoélectriquement le rayonnement émis pour produire un signal d'image électrique.
