  • Optical relay providing a projected image presenting characters having an enhanced readability
    Patent number: 4866529
    Abstract: The invention relates to an optical relay which includes a target plate of an electrically insulating material and allowing the light to pass in a manner dependent on the electric field parallel to the direction of propagation of this light, means for scanning a first surface of this target plate by means of an electronic beam (34) controlled by a wehnelt electrode (34), an anode (38), an optically transparent plate (38) which is electrically conductive and which receives the visual information electric signal from an amplifier which supplies a video signal. The optical relay operates with a further amplifier (52) which applies a small overmodulation supplied by the video signal to the wehnelt electrode in order to enhance the readability. The overmodulation may be automatically controlled by means of a picture integrator.
