  • Image tube for producing optical images with high resolution
    Patent number: 4360759
    Abstract: An image tube for electrical measurement of optical images comprises a vacuum vessel having a photocathode at one end and a mesh intermediate its ends. The images are produced with high resolution when the distance from said photocathode to said mesh (L.sub.1) and the total extension (L.sub.2) along a central axis of the tube in the path of movement of the electrons are selected by means of the following mathematical relations: ##EQU1## the symbol n denoting an integer indicating the number of revolutions rotated by the electrons along their path of movement.
