Paper Abstract

Integral imaging has been received much interest due to its various advantages. However, the narrow viewing angle is one of the bottlenecks of this technique. Basically, the viewing angle is limited because the displayed area of elemental images is confined. In addition, the interference of neighboring elemental lenses causes the integrated image overlapping. Recently the viewing-angle-enhanced scheme with lens switching has been proposed. In that scheme, a mechanical moving part with fast speed to obtain a natural after-image was required. In this paper, we propose and demonstrate a novel scheme of integral imaging using a mask with two devices to enhance the viewing angle. This is implemented by two identical systems that consist of a lens array and a display panel. The images from the two sets of devices are combined with a beam splitter. A mask that has alternately repeated on/off patterns in an array form is attached to each lens array and the area of on/off in two masks are opposite (interleaved). The integrated images in each system are combined spatially and the viewing area is doubled. Thus, it can be stated that spatial multiplexed images instead of the time-multiplexed images contribute to enhance the viewing angle of integral imaging without any mechanical movement.
