Abstract

Pour corriger l'orientation des faisceaux et ainsi la pureté des couleurs dans des tubes-images couleur, en particulier des tubes-images à systèmes de déviation montés fixes, un champ continu est prévu en aval du champ de déviation. Il fait tourner la trame autour du faisceau central non dévié et produit, par exemple dans le cas d'une commutation sur rouge uniquement, une surface rouge nette au voisinage du faisceau central qui peut etre amenée au centre de l'écran au moyen d'aimants de pureté de couleur.
