Abstract
A structure ( ) is located relative to a reference surface ( ) using an optical target ( ) affixed to the structure ( ) and having a reflective angular-reference hologram ( ) thereon with an effective angular orientation. An alignment light beam ( ) is directed perpendicular to the reference surface ( ) and incident upon the angular-reference hologram ( ) on the optical target ( ), and a signal return of the alignment light beam ( ) is received at a measurement location. The angular orientation of the structure ( ) is adjusted to achieve a signal return of the alignment light beam ( ) corresponding to an alignment of the alignment light beam ( ) to the effective angular orientation of the reflective angular-reference hologram ( ). Multiple reflective angular-reference holograms ( ) may be spatially superimposed upon each other in the optical target ( ) or spatially separated from each other on the optical target ( ).
