Sven-Erik writes "Video projectors able to project high-quality images will be embedded in your cellphones and laptops within two years. This is the promise of a new technology developed at Cambridge University. These pocket projectors will have no lenses and no light bulbs. Instead, these future battery-powered tiny projectors will rely on holographic technology and special algorithms. In 'Holograms enable pocket projectors,' Technology Research News explains that a 2D hologram will be created on a microdisplay and projected by using a laser beam. This has been possible because the researchers have written special algorithms which generates the holograms a million times faster than standard ones."
