Abstract Electro-optical display system for providing a composite display of an optical image wherein a first image provided by means of a cathode ray display device is superpositioned onto a second image derived from hard copy information such as slides, maps or other character information. The system is comprised of a cathode ray tube with suitable means for directing a first light image generated by the cathode ray tube onto the photocathode of an image intensifier. The second image which may be projected by means of a slide projector is also focused onto the photocathode of the image intensifier. These two images directed onto the photocathode generate an electron image corresponding to the composite image of the first and second image. This electron image is then accelerated and amplified through the image intensifier to provide a visible light display by means of a suitable phosphor positioned at the opposite end of the image intensifier with respect to the photocathode. This output visible image is a composite image of the first two images.
An electro-optical system comprising a cathode ray display means for providing a first image representative of dynamic information of a scene, a second means for providing a second image representative of stationary information of the scene and different than said first image, an image converter tube comprising a photocathode and an output phosphor display screen, a half silvered mirror positioned in the optical path between said display means, said second means and said image converter tube so as to combine said first and second images and direct the composite image display to said image converter tube, and an optical system for focusing said first and second images onto the photocathode of said image converter tube to generate an electron image from said photocathode representative of the composite display of said first and second images, and means for accelerating and focusing said photoelectron image onto said phosphor output screen to provide a visible display representative of the composite display of said first and second images.
