ABSTRACT:
An airborne display system is provided for viewing a high-definition collimated video image or a high-resolution collimated synthetic image or a combination of both images in superimposed relation by means of head-down display devices mounted on an aircraft instrument panel. The display system comprises a first head-down collimating assembly constituted by a monochrome cathode-ray tube and an optical objective, and a second head-down collimating assembly constituted by a color cathode-ray tube and the same collimating objective. An optical relay device is associated with a partly transparent mirror for transmitting the monochrome image and deviating the intermediate color image formed by the optical relay device to the objective. The reflected image as well as the transmitted image are both located at a distance from the optical objective which is equal to the focal distance.
