    Abstract: A holographic display includes "segmented" images (24) configured as if positioned in separate viewing "cells" (28, 28a corresponding spatially to preselected subareas of a desired display area with invisible segmenting cell sides. Constantly viewable unsegmented holographic images recorded in the same recording medium (16 min ) as the segmented images or on a separate recording medium can be multiplexed into the display area using a conjugate light source (50) of a different frequency or having a different polarization condition (e . g., unpolarized) from the conjugate light source (20) used to project the segmented images to be selectively displayed/blocked.
