Cheap Holograms Could Give Rise to Glasses-Free 3D TVs

cantikkkkkkkLarge and affordable holographic video displays may soon be possible, which could spur the development of glasses-free 3D TVs, researchers say. The secret to developing such holographic video displays could be using acoustic waves to control the way a crystal bends light, the scientists added. Holograms are a special kind of 2D photograph that, when lit up, create the illusion of a 3D image. The pixels making up each hologram scatter light falling onto them in very specific ways, causing these light waves to interact with each other to generate an image with depth Read Full Article
