2. Holographic optical element - Wikipedia

   en.wikipedia.org/wiki/Holographic_optical_element

   Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction. HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies. The shape and structure of the HOE is dependent on the piece of hardware it is ...

3. Holography - Wikipedia

   en.wikipedia.org/wiki/Holography

   Two photographs of a single hologram taken from different viewpoints. 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.

4. Holographic display - Wikipedia

   en.wikipedia.org/wiki/Holographic_display

   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.

   The first record album cover to have a hologram was "UB44", produced in 1982 for the British group UB40 by Advanced Holographics in Loughborough. This featured a 5.75 inch square embossed hologram showing a 3D image of the letters UB carved out of polystyrene to look like stone and the numbers 44 hovering in space on the picture plane.

6. Computer-generated holography - Wikipedia

   en.wikipedia.org/wiki/Computer-generated_holography

   Computer-generated holography. Computer-generated holography (CGH) is a technique that uses computer algorithms to generate holograms. It involves generating holographic interference patterns. A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography. [1]

7. Leia (company) - Wikipedia

   The company was founded in 2014 as a spin-off of HP Labs. [1] Its research into the holographic display concept under HP was published by Nature in 2013. [2] CEO David Fattal explained that its diffraction system would address shortcomings with other mobile 3D display systems, such as being able to be seen by multiple viewers at once, using the display in its original 2D mode with no loss of ...
