Holography. Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave.
A holographic display is a type of 3D display that utilizes light diffraction to display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image, and do not cause a vergence-accommodation conflict.
ESPI fringes – flat plate rotated about a vertical axis – the fringes represents displacement in the viewing direction; the difference in displacement between fringes is about 0.3 μm. Electronic speckle pattern interferometry (ESPI), [1] also known as TV holography, is a technique that uses laser light, together with video detection ...
Currently, Katsur predicts a future that looks a lot like the TV of the past — maybe a monthly fee for streaming services supported by ads or whatever the business model for content TV.
Billing itself as the world’s “first holographic communications platform,” US startup Proto is beaming life-size, “3D” video into universities, hotels and medical centers.
Holodeck. A vacant holodeck on the Enterprise -D; the arch and exit are prominent. The Holodeck is a fictional device from the television franchise Star Trek which uses "holograms" (projected light and electromagnetic energy which create the illusion of solid objects) to create a realistic 3D simulation of a real or imaginary setting, in which ...
Our screens are getting much bigger — and as they blow up, the way they work is changing. Scripps News digs into the evolving technology, business models and future of television that are all on ...
Holography is often used as a plot device in science fiction, appearing in a wide range of books, films, television series, animation and video games. Probably the first reference is by Isaac Asimov in his Foundation series starting in 1951. Holography has been widely referred to in movies, novels, and TV, usually in science fiction, starting ...
