Abstract
A pipe alignment system and method is provided for positioning a pipe line along a predetermined path. A light transmitter generates a reference light beam along which the pipe line is to be positioned. The light beam has wavelengths substantially in the green portion of the optical spectrum. An optical target is positioned at one end of each pipe section to assist in alignment thereof. Preferably, the optical target has a green tint which filters the green light from ambient light. The optical target may also have reference indicia thereon to assist in aligning the target with the reference beam of light.
