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.
Hebrew astronomy refers to any astronomy written in Hebrew or by Hebrew speakers, or translated into Hebrew, or written by Jews in Judeo-Arabic.It includes a range of genres from the earliest astronomy and cosmology contained in the Bible, mainly the Tanakh (Hebrew Bible or "Old Testament"), to Jewish religious works like the Talmud and very technical works.

The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region – such as a light-like boundary like a gravitational horizon.
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.
Like a hologram, a discrete correlograph can recognize displaced patterns and store information in a parallel and non-local way so it usually will not be destroyed by localized damage. [34] They then expanded the model beyond the correlograph to an associative net where the points become parallel lines arranged in a grid.
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.
