Abstract:
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; andg. chamber means for forming a vacuum enclosure between said substrate and said first side of said optically transparent body.
