The hologram keeps the information on the amplitude and phase of the field. Several holograms may keep information about the same distribution of light, emitted to various directions. The numerical analysis of such holograms allows one to emulate large numerical aperture, which, in turn, enables enhancement of the resolution of optical microscopy.
The notes use printed patterns to generate holograms of the portraits facing different directions, depending on the angle of view, employing a technology that Japan's National Printing Bureau says ...
A thick or volume hologram [1]: Section 4.2 is one where the thickness of the recording medium is greater than the spacing of the interference pattern. The recorded hologram is now a three dimensional structure, and it can be shown that incident light is diffracted by the grating only at a particular angle, known as the Bragg angle. [10]
Since its introduction, vibrometry by holographic interferometry has become commonplace. Powell and Stetson have shown that the fringes of the time-averaged hologram of a vibrating object correspond to the zeros of the Bessel function (), where (,) is the modulation depth of the phase modulation of the optical field at , on the object.

Volumetric printing has been called "Hologram 2.0" by a company marketing the technology. Volumetric prints however are not produced in the same manner as holograms , in that there is no interference pattern generated or used in basic volumetric prints.
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.

Blade Runner Style Holograms. This is why I came to CES. This is the shit I want, like the Blade Runner 2049 meme. The London-based software company Hypervsn made a splash on the Las Vegas ...
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.
