Abstract:
A planar alignment system for aligning a first planar surface parallel to a second planar surface comprising:a target base, releasably attachable to the first planar surface, said target base having a first planar reflective surface positioned parallel to the first planar surface;a reflector, releasably attachable to the second planar surface, said reflector having a second planar reflective surface positioned parallel to the second planar surface;a radiation transmitter, releasably attachable to one of the planar surfaces, for transmitting a radiation beam, perpendicular to the planar surface to which it is attached, toward the planar reflective surface of the other planar surface; anda planar target, positioned parallel to one of the planar surfaces and radially disposed about said transmitted radiation beam, wherein said radiation beam is reflected between said planar reflective surfaces and strikes said planar target, producing a calibration point whose displacement from said originally transmitted radiation beam is indicative of the positional alignment between the first planar surface and the second planar surface.
