ABSTRACT:
A laser system is provided for precisely locating points in space relative to a reference plane. The system includes at least one laser generator capable of sweeping a plurality of mutually perpendicular laser planes and/or one laser plane and one laser beam perpendicular thereto. The system further includes a plurality of laser sensitive targets. Three laser sensitive targets are positioned to lie in the first plane swept by the laser generator. These targets then define a reference plane. The laser generator may be moved periodically and bucked into the previously established reference plane. The second laser plane or the laser beam will be perpendicular to the reference plane at each optional position of the laser generator. Thus, each second laser plane or each second laser beam will be parallel to one another. The system may further include position sensors for precisely defining distances between the parallel laser planes or parallel laser beams.
