Abstract

Tube d'images servant à reproduire des images colorées, constitué par une fenêtre d'image, un cône et un col, et comprenant, du côté de l'écran d'image, des moyens munis d'éléments de correction disposés près de chaque faisceau, ces éléments déformant en tonneau un premier champ de déviation engendré du côté du col près de chaque faisceau et en coussin un deuxième champ de déviation également engendré du côté du col près de chaque faisceau, dans le but de réduire fortement les effets de la défocalisation par déviation sur l'écran d'image. Application : téléviseurs en couleurs.
