  • Patent number: 4078850
    Abstract: A pair of horizontal rods of fiber optic bundles extend into a light box from external high intensity light sources. Light from the rods is directed upwardly via fixed mirrors, and thence horizontally and vertically to a viewing plate via pairs of mirrors supported in rotatable arms. Secured in the mirror arms are bearings that are rotatable in support plates, the axes of such bearings being coaxial with respective rhomboid arms. The mirror arms are caused to track the movements of the rhomboids, and different arrangements are disclosed for effecting such tracking, including external motors having shafts coupled via gears to the bearings and a servo control network with inputs from potentiometers representing the relative positions of the mirror arms and the rhomboids coaxial thereto, and pulleys and belt arrangement extending between coaxial arms.
