ABSTRACT:
An apparatus for detecting the relative position and orientation of a reference beam of light includes first and second detectors for detecting the intersection of the reference beam with first and second spaced and substantially parallel reference planes. The measured horizontal and vertical deviations between the points of intersection on the two reference planes provide an indication of the orientation of the beam with respect to the apparatus.
