Abstract: Sequentially appearing video signals as may be generated by means of a single scanning beam are processed for display in a plurality of simultaneously appearing beams of a charged particle beam scanner. Video signals corresponding to each of the scanning beams are successively fed to corresponding hold circuits, the number of such hold circuits corresponding to the number of scanning beams. The scanner has a plurality of beam channels defined between an area charged particle source and target with control plate means simultaneously controlling the scanning of each of the beams in these channels. A modulator control plate also is included for simultaneously controlling the intensity of each of the beams. Video signals are simultaneously fed from the hold circuits to corresponding beam control electrodes of the modulator control plate to provide simultaneous modulation of all of the beams. In this manner successive groups of consecutively arriving video signals, are memorized in hold circuits and then simultaneously used to modulate corresponding beams which are controlled to scan the target.
