ABSTRACT:
A novel method that is suitable for uniquely aligning remote first and second objects. In one aspect, the method comprises pre-alignment and alignment stages. The pre-alignment stage comprises generating first and second geometric configurations on the first and second objects, respectively. The first configuration is, at least in part, characterized by randomness; and, the second configuration comprises a geometric complement of a projection of the first configuration. The alignment stage exploits variable geometries generated in the process of manipulating each of the two objects through six degrees of freedom, until a unique geometry, signifying alignment, is realized.
