Laser mapping tool and weapon replacement fixture

摘要

A platform mapping tool for mapping a weapon platform includes a mandrel inserted in one of a weapon barrel and a weapon replacement fixture barrel. The tool generates a laser cone centered on the bore centerline of the weapon. The laser cone illuminates a defined cone of dispersion of ammunition. Areas where the laser cone intersects the weapon platform correspond to undesirable weapon firing positions. The undesirable firing positions can be digitized and loaded into the weapon's fire control system.

主权项

1. A platform mapping tool, comprising:
a base wheel having a central axis; an adjustable kinematic mount spaced apart from and rigidly fixed to the base wheel, the kinematic mount being centered on the central axis; and a laser cone generator fixed to the kinematic mount and centered on the central axis, the laser cone generator including a laser, a diffractive optical element, a lens tube, and lenses disposed in the lens tube, the lenses including first and second plano-convex lens and a plano-concave lens wherein a laser beam from the laser source is transformed by the diffractive optical element and the lenses into a diverging ring with an angular divergence that is invariant of a focus of the diverging ring.
