Thus, a hologram can be broken up into small pieces and each one will enable the whole of the original object to be imaged. One does, however, lose information and the spatial resolution gets worse as the size of the hologram is decreased – the image becomes "fuzzier". The field of view is also reduced, and the viewer will have to change ...
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.
The developed hologram is illuminated by a beam similar to the original reference beam. A re-constructed image of the original real image can be seen by an observer located to the right of the hologram. However, this image will appear as if it is being viewed through the re-constructed slit to the right of the plate.
On display in the gallery are a variety of different types of holographic images, including a collection of celebrity hologram portraits. There are also cylindrical 360° floating images, multiple image holograms that change as you walk by, and computer generated holograms as well as a selection of novelty hologram items and stickers.
Microsoft's HoloLens now allows users to interact with AR objects as if they were real ones, even enabling them to manipulate the objects like a Jedi. The post Controlling AR Holograms with ...
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.

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.
Digital holography comes in different flavors, such as off-axis Fresnel, Fourier, image plane, in-line, Gabor and phase-shifting digital holography, [2] depending on the optical setup. The basic principle, however, is the same; a hologram is recorded and an image is reconstructed by a computer.
