ABSTRACT:
A laser beam pointing system, adapted for use in an aircraft. A preferred embodiment of the system includes: a laser beam source, within the aircraft, emitting a laser beam; and, a plurality of laser beam pointing devices in optical alignment with the laser beam. Each pointing device includes: a cylindrical shaped rotatable housing with a window, and either one or two rotatable optical means in optical alignment with the laser beam. One preferred arrangement is the mounting of one pointing device on the upper external surface of the aircraft fuselage, and of another pointing device on the lower external surface of the aircraft fuselage in a location oppositely disposed to and below the other pointing device, with the two pointing devices being in parallel relationship to each other, and with the pointing devices mounted flush with the aerodynamically configurated external surfaces of the fuselage. Another preferred arrangement is the mounting of one of the pointing devices on the leading edge of a left side fairing of the aircraft, and of another pointing device on the leading edge of the right side fairing of the aircraft angularly positioned with respect to the other pointing device, so that their respective axes are in the same plane and the axes would intersect if extended, and with the pointing devices mounted flush with the aerodynamically configurated leading edge of the respective fairings. This inventive system, unlike the prior art, permits the emitted laser beam to be projected over a broad range of angles with little or no aerodynamic interference with the aircraft on which it is mounted and used.
