![]() ![]() ![]() In our conventional holographic device, we will have a reference beam that is concentrated on a recording surface and another beam of light concentrated on an object. These holograms are facilitated by the principle of interference. Traditional holograms are created by the modulation of light phases to produce the illusion of depth. The researchers, headed by Professor Min Gu from RMIT University in Melbourne, Australia, and members from the Beijing Institute of Technology claim they were able to create a hologram from a surface just nanometers thick. Recently, there have been a few major breakthroughs in holographic technologies to bring us one step closer to its sci-fi counterpart.Ī research paper published earlier this week discusses the work of a team of researchers that have been able to successfully produce the world’s thinnest hologram. These holograms are capable of being produced in a 3D manner with both perspective and parallax, giving the images a realistic change with regards to the perspective of the observer. Essentially, what we have today is a photographic recording of a light field, instead of a lens-formed image. Recent developments, however, may soon change that.Ĭurrent consumer holograms are not "true" freestanding holograms. For optical engineers, the technology to create a true freestanding hologram has been considered to be nearly unattainable. Holograms have been a basic feature of science fiction books and movies for the majority of the last century.
