A thin hologram [1]: Section 4.1 is one where the thickness of the recording medium is much less than the spacing of the interference fringes which make up the holographic recording. The thickness of a thin hologram can be down to 60 nm by using a topological insulator material Sb 2 Te 3 thin film. [9]
In general usage, a hologram is a recording of any type of wavefront in the form of an interference pattern. It can be created by capturing light from a real scene, or it can be generated by a computer, in which case it is known as a computer-generated hologram, which can show virtual objects or scenes.
Billing itself as the world’s “first holographic communications platform,” US startup Proto is beaming life-size, “3D” video into universities, hotels and medical centers.
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.
Government scientists working out of trailer in Illinois are testing out the hypothesis that we're all living in a holographic world. Yes, that means that Albert Einstein may not have been totally ...

This explains why scratch hologram images are subject to distracting distortions and collapse of the depth image outside of a very narrow field of view --- circular arcs are a fairly poor approximation to rainbow hologram fringes. Beaty also pointed out that the rainbow hologram of a single point is a rectangular section of nested parabolics. [5]
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.
