Abstract: A light valve comprising a first transparent electrically insulating layer, a first transparent electrically conductive layer, an electro-optic imaging medium layer, a first dielectric mirror, a light separating layer comprising an organic dye, organic pigment, or a semiconductor selected from the group consisting of As, Se, Te, Bi, Sb, Fe, Si, S or alloys thereof, a second dielectric mirror layer, a photoconductor layer, a second transparent electrically conductive layer and a second transparent layer. This light valve may be utilized in systems which include an imaging light source and a read-out light source.

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.
