Abstract
A video display system utilizing a video source and an image intensifier having a substrate. A video image source positions at the substrate to provide a photon signal. A photocathode element at the substrate converts the photon signal into electrons. An optically transparent body having first and second surfaces is placed opposite the substrate spaced therefrom. A vacuum chamber is formed between the substrate and the first surface of the second optically transparent body. A fluorescing layer is positioned on said first surface of the second optically transparent body. A source of electrical power provides a voltage potential between the photocathode layer and said fluorescing layer. The intensified video image exits the second surface of the second optically transparent body for viewing.
Claims10
A video display system comprising:
- a. a video image source;
- b. an image intensifier including a substrate, the video image source providing a photon signal at said substrate;
- c. a photocathode element positioned adjacent said video image source;
- d. an optically transparent body, said optically transparent body including a first side and a second side;
- e. a fluorescing element positioned on said first side of said optically transparent body;
- f. photon baffle means for sheltering said photocathode element from photons being returned thereto, said photon baffle means including a plurality of dynodes spaced from one another to form a gap to permit egress of photons from said photo cathode element, said plurality of dynodes overlapping one another to prevent passage of photons from said fluorescing element;
- and
- g. chamber means for forming a vacuum enclosure between said substrate and said first side of said optically transparent body.
