Abstract
A process to optically align optical systems on a weapon is disclosed. Several different embodiments of the system and method are disclosed. The use of this process/system will ensure a well aligned weapon with mounted optical systems. It can find applications in aligning rifle scopes, aiming lasers, laser range finders, tactical engagement simulation lasers, e.g., MILES, etc.
Claims16
A mirror-based optical alignment system, comprising:
- A weapon mounted with at least one of a scope, a borelight and a laser range finder, each having a parallel optical path;
- a mirror optically shaped to have a focal length, the mirror being adjustably disposed at an offset angle to reflect said parallel optical paths at a reflection angle and focus said reflected optical paths on a focal point of a focal plane sufficiently distanced from said parallel optical path;
- and
- a target card placed proximately along said focal plane of the mirror such that said reflected parallel optical paths are focused to converge onto said focal point where the target card is placed.

A lens-based optical alignment system, comprising:
- a weapon mounted with at least one of a scope, a borelight and a laser range finder, each having a parallel optical path;
- a refractive lens element, the refractive lens element being adjustably disposed to refract said parallel optical paths incident on one side of said refractive lens element and focus said optical paths on a focal point of a focal plane disposed on an opposite side of said refractive lens element;
- and
- a target card placed proximately along said focal plane of the refractive lens element such that said refracted parallel optical paths are focused to converge onto said focal point where the target card is placed.
