Abstract
An assembly for displaying an interlaced image. The assembly includes an interlaced image, which may be digitally or web printed for example, with sets of elongate image elements or slices. A lens arrays is provided with a first side proximate the interlaced image such as a planar surface and a second side distal the image with numerous lens sets. Each of the lens sets is paired with one of the sets of the image elements and includes a number of linear or elongate lenses that are each mapped to one to three image elements. The lenses are each configured to focus light from the subset of image elements to a viewer along a focus direction or line. The lenses are configured to provide a lens-specific viewing angle with a focus line, and the focus line to the paired image element subset differs from other lenses or is unique.
