Abstract
The projector includes a housing with a projection path duct holding a dove prism and a mirror deflecting the path into a vertical axis. The beam in that path is intercepted by a tiltable mirror held in a rotatable disk. A transmission which includes bevel gearing, shafts and worm gears couples the tiltable mirror to a computer controlled motor for adjusting the elevation of the projection. Other transmission devices, including gears and worm gear, couple the disk to another motor to causing the projection beam to project in different horizontal directions. The projector is used to superimpose particular images upon a background image in a ship simulator.
