Optical fiber television screen

摘要

Video Receiving Apparatus having a fiber optic display screen arranged substantially normally to a beam of electrons projected from an electron gun. The display screen compromises a plurality of optical fibers arranged in aligned relationship to form a bundle of parallel fibers which are extremely short in length. Each fiber has a light receiving face spaced from a light emitting face with there being sufficient light emitting faces to provide for the formation of a suitable image on a television screen. Each light receiving face is arranged at an angle respective to the beam of electrons which is less than the critical angle of the glass fiber. The axial center line of one end of each glass fiber lies normal to the viewing screen and laterally to the beam of electrons.
