Title (EN) IMAGE PICKUP TUBE
(FR) TUBE DE PRISE D"IMAGES
Abstract:
(EN) An image pickup tube has markers for discriminating the four corner positions from the effective image pickup zone, which extend corresponding to the four corners of the effective image pickup zone of the electron beam in a transparent electrode patterned on the image pickup tube target, thereby providing a simple and effective adjustment of the scanning zone of the electron beam and the image pickup screen range during the assembly and manufacture of the image pickup tube.
(FR) Un tube de prise d"images présente des marqueurs permettant la discrimination des quatre positions de coins de la zone de prise d"images effective, qui s"étend par rapport aux quatre coins de la zone de prise d"images effective du rayon d"électrons dans une électrode transparente formant des motifs sur la cible du tube de prise d"images. Cet agencement permet un réglage aisé et efficace de la zone de balayage du rayon d"électrons et de la plage de l"écran de prise d"images pendant l"assemblage et la fabrication du tube de prise d"images.
