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.
When the hologram plate is illuminated by a laser beam identical to the reference beam which was used to record the hologram, an exact reconstruction of the original object wavefront is obtained. An imaging system (an eye or a camera) located in the reconstructed beam 'sees' exactly the same scene as it would have done when viewing the original.
He recorded rare butterfly box holograms with collectors, [9] [10] holograms recognized as exceptional worldwide and presented at the MIT Museum and other optical museums around the world. In 2015, he received the Denisyuk Medal [ 11 ] from the Russian Academy of Optics, for all of his work on colour holography.
Las Vegas, NV, Jan. 08, 2025 (GLOBE NEWSWIRE) -- Proto Inc. announced today at CES, the launch of the Proto M2 Foundation Series, the newest desktop hologram and spatial compute device. Proto is the original inventor of hologram machines and the platform that makes holoportation and AI-powered spatial compute possible.

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.

Ordinary holograms are three-dimensional images encoded in a two-dimensional surface, such as the hologram on a typical credit card. "This time, the entire universe is encoded," he said.
The rainbow hologram (also known as Benton hologram) is a type of hologram that was invented in 1968 by Dr. Stephen A. Benton at Polaroid Corporation (later MIT). [1] Rainbow holograms are designed to be viewed under white light illumination, rather than laser light which was required before this.
