An Experimental Simultaneous Color-Television System: Part II-Pickup Equipment

The technical development of the present flying-spot-type color-television pickup equipment is described. The use of a high-voltage kinescope with a short persistence phosphor, of the multiplier-type photo-tubes and dichroic filters, permit the construction of apparatus for flying-spot scanning of color slides and color motion picture film providing excellent color video signals. The circuit equalization for the phosphor persistence is described in detail. The use of the simple flying-spot scanner for studio pickup is described.
