摘要： An image display device (1) which includes a cathode ray tube is provided with a cathode system (2) for the emission of a plurality of electron beams (3) whereby a phosphor screen (4) is scanned in order to display an image. The electron beams are modulated on the basis of an electronic image signal by means of a cathode modulator (5). The cathode modulator is arranged to scan different image lines simultaneously by means of separate electron beams. For example, the cathode modulator comprises an extension system (7) and a delay system (8) for deriving extended and delayed extended image line sections from image line sections of the electronic image signal. The cathode modulator also comprises a combination unit (9) for simultaneously supplying an extended image line section and a delayed image line section with which separate electron beams are modulated.

摘要： Picture pickup device comprising a television camera tube having an electron gun, and a photo-sensitive target in an evacuated envelope. An electron beam generated by the electron gun is focused by focusing means onto the target. The electron beam is deflected by deflection means and describes a line raster across the target. The electron beam forms an elongated spot on the target. The longitudinal axis of the spot is perpendicular to the lines of the raster and has a length which is substantially equal to the line spacing. The elongated spot is obtained with the aid of an adjustable multipolar stigmator which, viewed in the direction of propagation of the electron beam, is provided in front of the focusing and deflection means, coaxially around the axis of the envelope and the electron gun. The shape of the spot can be adjusted in an optimum manner so that stern waves are completely suppressed. It is possible to provide the stigmator in or around the tube and to adjust it by magnetization, if required, through the wall of the envelope.
