- Holography - Wikipedia
A hologram represents a recording of information regarding the light that came from the original scene as scattered in a range of directions rather than from only one direction, as in a photograph This allows the scene to be viewed from a range of different angles, as if it were still present
- How Holograms Work | HowStuffWorks
In a hologram, the two intersecting light wave fronts form a pattern of hyperboloids — three-dimensional shapes that look like hyperbolas rotated around one or more focal points
- Hologram: definition, operation and uses
A hologram is a three-dimensional image obtained by recording the interference between two coherent light beams, generally coming from a laser It recreates the volume, depth, and angles of a real object, without glasses or headphones
- Holography | Optics, 3D Imaging Laser Technology | Britannica
Holography, means of creating a unique photographic image without the use of a lens 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 laser beam—organizes the light
- HOLOGRAM Definition Meaning - Merriam-Webster
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)
- Hologram Technology Explained: Types Uses (2026)

A hologram is created by splitting a laser beam into two paths One beam, called the reference beam, goes directly to a recording surface (like a special film or plate) The other beam bounces off the object being recorded
- Different Types of Holograms – Holocenter
The hologram does not change the wavelength (color) of light but controls how light is re-directed There are a number of distinct types of art holograms that can be defined by their optical-geometry and the recording medium
