Abstract
Abstract Illuminating light from a plurality of light bulbs is converged into a collimated beam by a coalescing optical fiber bundle to extract images from dynamic and static data sources positioned along the optical axis of the beam. A beam splitter transmits the combined images to a display screen through a folded projection fiber bundle and to sensors for extraction of image signals fed as inputs to a computer controlling image changes in the static data source, scanning operation of the dynamic data source, and light intensity and color of the illuminating light.
