Through manipulation of this multispectral light field data, digitally refocused spectral images may be created at different, selectable focal depths, with a single exposure..

Device for the projection of images, at point of sales, simulating a holographic image


Are already known several projection equipment, and various forms of use, using screens, walls, and using synchronized sound output with the images, the screens are typically hung by wire, canvas laid down on walls and others, and possess at least one of their white faces, or projections made directly on walls, which are static plans, besides being too big, and with that demand large structures, requiring fit computers, projector and/or televisions, and a large space in the markets and shops, which becomes very expensive and difficult handling of, requiring several people to assemble, operate and dismantle all equipment.. .
