Abstract (en)

[origin: WO9806217A1] A video display system utilizing a video source (12) and an image intensifier (14) having a substrate (18). A video image source (12) positions at the substrate to provide a photon signal (22). A photocathode element (38) at the substrate converts the photon signal into electrons. An optically transparent body (18, 24) having first and second surfaces is placed opposite the substrate spaced therefrom. A vacuum chamber (32) is formed between the substrate and the first surface of the second optically transparent body. A source of electrical power (44) provides a voltage potential between the photocathode layer (38) and the second fluorescing layer (40). The intensified video image exits the second surface (28) of the second optically transparent body for viewing.
