ABSTRACT:
A hologram structure including a plurality of holograms having substantially identical reconstruction characteristics disposed on a substrate for rotation about a rotation axis and containing segments of a composite image. The holograms are angularly offset relative to each other about a rotation axis such that the composite image is visible over at least one narrow solid angular region pursuant to rotation of the holograms about the rotation axis and illumination of the holograms with a reconstruction beam.
