US 4015906 · granted 1977-04-05
Abstract
An alignment device for aligning a beam of radiant energy, particularly a laser beam, with respect to a target comprises a reflector in the path of the beam, the reflector having an aperture of a diameter smaller than that of the beam so that the aperture permits the center portion of the beam to pass therethrough to the target, while the outer marginal fringe of the beam is intercepted and reflected to a sighting member, the device further including an optical system transposing the image of the sighting member onto the field of the target, thereby enabling real-time alignment of the beam and providing a better defined beam and while permitting the alignment to be effected before directing the beam to the target.

Claim 1
An alignment device for aligning a focussed beam of radiant energy with respect to a target comprising: means in the path of the focussed radiant energy beam for dividing said beam into a first portion and a second portion, said beam dividing means being formed as an aperture having a diameter smaller than the diameter of the radiant energy beamwhich permits the first portion of the beam to pass therethrough to the target and reflects the remainder of said radiant energy beam to form said second portion of the beam; a shutter for selectively intercepting said first portion of the beam between said beam dividing means and said target; a sighting member intercepting said second portion of the beam; an optical system for viewing the sighting member and the target with said sighting member and said target imaged on one another; and means for adjusting the position of said first portion of the beam on said target by adjusting the position of said second portion of the beam on said sighting member while said sighting member and said target are imaged on one another.
