Abstract

Tête d'impression utilisant un tube cathodique à émission par effet de champ pour une imprimante optique permettant d'imprimer sur des surfaces photosensibles. Une pluralité de petits ensembles électroniques constitués de cônes (26) émetteurs cathodiques dans une ouverture anodique forment un espace qui est inférieur au libre parcours moyen des électrons dans une atmosphère ambiante et les ensembles sont de préférence étroitement espacés de manière à former un faisceau en colonne. De préférence, une troisième électrode accélère et nettoie le faisceau qui est séparé de la cathode (24). Ledit faisceau est ensuite incident sur un film (34) luminophore qui est excité, générant ainsi de la lumière. La lumière est transmise à travers une plaque avant émettrice (36), telle qu'une plaque à fibres optiques, où elle est incidente sur le matériau photosensible. Des transmissions multiples d'une seule couleur permettant d'accélérer l'impression par intégration des temps de propagation sont également décrites.
