ABSTRACT:
A method and apparatus for aligning individual sections of pipe includes directing a beam of collimated light in the general direction of the pipeline and scanning the beam laterally. A target, having a retro reflective portion, is positioned in a location that will be traversed by the scanning beam. A reflection of the beam produced by the reflective portion is received and processed. The scanning is discontinued when the reflective portion is located and the beam is aimed in a direction related to the position of the retro reflective target.
