A hologram is a recording of an interference pattern that can reproduce a 3D light field using diffraction. In general usage, a hologram is a recording of any type of wavefront in the form of an interference …

Aug 30, 2023 · They're two-dimensional surfaces that show absolutely precise, three-dimensional images of real objects. You don't even have to wear special glasses or look through a View-Master to …

A hologram is a picture of a "whole" object, showing it in three dimensions. We've all seen cheap hologram images on credit cards and ID cards (where they help prevent copying).

A holographic image can be seen by looking into an illuminated holographic print or by shining a laser through a hologram and projecting the image onto a screen.

Dec 20, 2025 · The photographic recording of the image is called a hologram, which appears to be an unrecognizable pattern of stripes and whorls but which—when illuminated by coherent light, as by a …

Jun 10, 2025 · Holograms create three-dimensional images by using light interference patterns from laser beams. Lasers make holograms because their light is coherent, meaning it has the same …

To produce a simple hologram, a beam of coherent, monochromatic light, such as that produced by a laser, is split into two beams. One part, the object or illumination beam, is directed onto the object …

The name hologram means “entire picture” (from the Greek holo, as in holistic) because the image is three-dimensional. Holography is the process of producing holograms and, although they are …

Apr 17, 2025 · An easy-to-understand explanation of what holograms are, how they're made, and what they can be used for.

A hologram is a true three-dimensional image recorded on film by lasers. Holograms are used for amusement; decoration on novelty items and magazine covers; security on credit cards and driver’s …
