ABSTRACT:
An optical spatial address system wherein a collimated light beam which is deflectable in a predetermined manner strikes a backdrop having one or more sets of reflecting facets thereon to direct the beam to a unique point in a three-dimensional space as defined by the predetermined deflection of the light beam for the case of two sets of facets. The facets are designed to preferably direct the beam from the source from the first set of facets along an axis in three-dimensional space to the second set of facets, the latter facets directing the beam along an axis orthogonal to the direction of the beam impinging thereon.
