Patent ID: 8402665

Claim:
An apparatus for generating laser reference planar projections comprising of: a first, a second, and a third means for generating, respectively, a first, a second, and a third incident laser beam and for directing, respectively, said first, said second, and said third beam along, respectively, a first, a second, and a third central axial orientation; a first, a second, and a third means for dispersing, respectively, said first, said second, and said third incident beam along, respectively, said first, said second, and said third axial orientation, wherein said first, said second, and said third dispersing means are, respectively, fixed relative to said first, said second, and said third beam generating means; and a first, a second, and a third means for normalizing, respectively, said first, said second, and said third dispersed beam by optical refraction; wherein said apparatus is capable of projecting, respectively, a first, a second, and a third substantially uniform, substantially planar, and omnidirectional laser reference projection; and wherein the relative position between said first normalizing means and said first dispersing means, the relative position between said second normalizing means and said second dispersing means, and the relative position between said third normalizing means and said third dispersing means are operably aligned, such that said first, said second, and said third reference projections are substantially orthogonal, respectively, to said first, said second, and said third axial orientations, and such that said first, said second, and said third reference projections are of a character suitable for visual alignment, measurement, and guidance in the construction field.
