ABSTRACT:
A cathode ray tube is coated on the inside of its fiber optic front plate with a broad band phosphor. In front of the front plate a second fiber optic plate is located. Three parallel strips of dichroic color filters are vapor deposited on the inside of the second plate. Optical contact between the two optical fiber plates is established by a layer of immersion oil. A photosensitive material is moved at a slight distance along the second fiber optic plate transversely to the color filter strips so that it will be exposed line by line. The use of filters in place of different phosphors to produce the individual colors produces significantly improved color separation and thus better reproduction of the image, while retaining the inherent advantages of fiber optic plates.
