LENSLESS FLYING-SPOT SCANNER FOR GENERATING COLOR SIGNALS

摘要

A color transparency is placed on the face of a flying-spot scanning cathode ray tube whose light spot is raster scanned in a conventional fashion. Three juxtaposed photomultipliers are placed a given distance in front of the cathode ray tube to collect the light transmitted by the transparency. Three primary color signals are selected by the use of appropriate color filters which cover the respective faces of the three photomultipliers. The image parallax resulting from this arrangement is compensated electrically by delay lines at the photomultiplier outputs.
