360-Degree-Viewable Tabletop Light-Field 3D DisplayHaving Only 24 Projectors
Conventional light-field methods of producing 3D images having circular parallax on a tabletop surface require several hundred projectors. Our novel approach produces a similar light field using only 1/10 the number of projectors. Adopting our method, two cylindrical mirrors are inserted in the projection light paths. By appropriately folding the paths with the mirrors, we form any viewpoint image in an annular viewing area from a group of rays sourced from all projectors arranged on a circle.
