Holographic display


A holographic display is a type of display that utilizes light diffraction to create a virtual three-dimensional image of an object. Holographic displays are unique from other forms of 3D imaging in that they do not require the aid of any special glasses or external equipment for a viewer to see the image.

1947 - British scientist Dennis Gabor first came up with the concept of a hologram while trying to improve the resolution of electron microscopes. He derived the name for holography, with "holos" being the Greek word for "whole," and "gramma" which is the term for "message."

1960 - The world's first laser was developed by Russian scientists Nikolay Basov and Alexander Prokhorov, and American scientist Charles H. Townes. This was a major milestone for holography because laser technology serves as the basis of most, if not all modern day holographic displays.

1962 - Yuri Denisyuk invented the white-light reflection hologram which was the first hologram that could be viewed under the light given off of an ordinary incandescent light bulb.

1968 - White-light transmission holography was invented by Stephen Benton. This type of holography was unique because it was able to reproduce the entire spectrum of colors by separating the seven colors that create white light.

1972 - Lloyd Cross produced the first traditional hologram by using white-light transmission holography to recreate a moving 3-dimensional image.

1989 - MIT spatial imaging group pioneered electroholography, which uses magnetic waves and acoustic-optical sensors to portray moving pictures onto a display

2005 - The University of Texas developed the laser plasma display, which is considered the first real 3D holographic display.

2010- Hollow pyramid shaped prisms are released into the consumer market, which if placed over a flat screen (or smartphone), can emulate a three-dimensional image by means of 2-D light refraction.

2012 - The first holographic display is implemented in a car's interactive navigation display system. The technology was showcased through the production car Lykan Hypersport.

2013- MIT researcher Michael Bove predicts that holographic displays will enter the mass market within the next ten years, adding that we already have all the technology necessary for holographic displays.
