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] When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
3D applications, or "holographic" applications, use Windows Holographic APIs. Microsoft recommends Unity engine and Vuforia to create 3D apps for HoloLens, but it's also possible for a developer to build their own engine using DirectX and Windows APIs .
In principle, it is possible to make a hologram for any type of wave. A hologram is a recording of an interference pattern that can reproduce a 3D light field using diffraction. In general usage, a hologram is a recording of any type of wavefront in the form of an interference pattern.
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.
So far, the only true color hologram we've seen come from a tiny, complicated display created by a Korean group led by LG, while the rest are just "Pepper's Ghost" style illusions.
Its flagship device, Microsoft HoloLens, was announced at the "Windows 10: The Next Chapter" press event on January 21, 2015. [2] The HoloLens provides an augmented reality experience where a live presentation of physical real-world elements is incorporated with that of virtual elements (referred to as "holograms" [a] by Microsoft) [3] [4] [5] such that they are perceived to exist together in ...

It is possible to make holograms of much less stable objects by using a pulsed laser which produces a large amount of energy in a very short time (μs or less). [7] These systems have been used to produce holograms of live people. A holographic portrait of Dennis Gabor was produced in 1971 using a pulsed ruby laser. [1]: Figure 4.5, p44 [8]
