Abstract: An optical fiber apparatus is disclosed for providing light to optical and other instruments from an auxiliary light source which may include a laser. A disclosed embodiment comprises a retinascope with a light source optically connected to a fiber optic bundle having its individual fibers aligned in the shape of a circle at its input end and in the shape of a rectangle at its output end. Ferrules hold and align the fibers at both ends. The light source may be a pulsed or continuous wave laser producing substantially monochromatic light, or any other suitable poly- or monochromatic light source. The retinascope includes a holder for supporting the output ferrule and the fiber bundle output.

Abstract: A novel decoy providing the deceptive appearance of a genuine three-dimensional object, such as a vehicle, is described which comprises a plurality of modular table units each of predetermined shape and assembled in an abutting relationship to form an outline of the vehicle, each said table unit supported by a framework including leg elements in a spaced relationship above the ground whereby a shadow is cast in said outline, to further the deceptive appearance of said decoy as viewed from the air, and a vertical element, supported by said assemblage of table units, in the shape of an elevational view of said vehicle, to provide a deceptive elevational view of said vehicle.

Abstract: An aircraft decoy is made by assembling metal or plastic pipe or tubing into tubing fittings to form the shape of an actual aircraft. The tubing is marked with location identification markings. The decoy thus constructed is easily disassembled, stored, transported, or reassembled. The aircraft decoy is covered with an open weave fabric to minimize air resistance so that high winds will not move the decoy on the ground. The fabric is coated with paint to mimic not only the optical characteristics or signature of the actual aircraft, but also the infrared and radar signature of the actual aircraft. Metal particles can be added to paint to increase the infrared and radar signatures.
