- 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
- 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
- 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 Technology: Understanding How it Works in 2024
Holograms provide a realistic visual experience that captures three-dimensional images without the need for special tools, like 3D glasses This effect is created through holography, an imaging process in which lasers are used to capture and replicate objects into detailed 3D pictures
- What is a Hologram? – Holocenter
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
- Introduction to Holography - ThoughtCo
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 frequency and phase Holograms are used in arts, data storage, security, and were improved by lasers invented in 1960
- Holography - HyperPhysics
Holograms are true three-dimensional images This is evidenced by the fact that you can move your head while viewing the image and see it in a different perspective This includes revealing part of the image which was hidden at another viewing angle
- Holography – University Physics Volume 3
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 recorded on photographic film, the process is quite different from normal photography
