Abstract
A boresight alignment method is used for aligning a laser with an optical sighting system in a laser designator or the like. The method includes selecting a target formed of a flat sheet of material, such as a metal foil, supporting the selected target at the focus of a collimating telescope in the path of a laser beam of a laser and optical sighting system combination, such as in a laser designator, focusing the laser beam onto the one side of the target, and burning an aperture in the target with the laser beam. The method includes illuminating the target burned aperture from the rear thereof with a visible light or with an infrared source and then aligning the optical sighting system with the illuminated target aperture. Both the day and night viewing optics can be aligned by providing pinhole illumination with multi-spectral target pinhole illumination. The target may be mounted so that it can be rotated to provide successive alignments of the same or different laser optical sighting systems. The target can be an aluminum foil supported on a metal frame or with a paper or polymer backing. An optical sighting system can be aligned to a laser with high accuracy under rugged military and industrial field operating conditions.
