Abstract
A reference signal used for orienting an object has a beam of electromagnetic radiation with a first signal component that is a rotating component and also a second signalcomponent which is periodically generated when the first signal component is in a predetermined direction. The beam may be a linearly polarized laser light beam with a rotating plane of polarization, an unpolarized laser light beam with a rotating and shaped image of predetermined configuration, or a linearly polarized microwave beam with a rotating plane of polarization. The second signal component may be generated as a component of the beam bearing the first signal component or separately generated and propagated. Provisions are made for receiving and comparing the direction indicated by the reference signal with the direction of the object to be oriented and the information derived from the comparison is analyzed and processed to provide an output signal that useful in orienting the object. The orientation of video displays, vehicles and parts of vehicles are illustrated.
