- Holography - Wikipedia
In principle, it is possible to make a hologram for any type of wave 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 pattern
- How Holograms Work - HowStuffWorks
Holograms, or holographs, are images that have parallax and depth These images are most commonly used to prevent forgeries, and can be found on licenses, credit cards and IDs
- Holography | Optics, 3D Imaging Laser Technology | Britannica
In the 1970s, Valerie Thomas invented a way to transmit three-dimensional images, or holograms, that appear to be real, which led to her invention of the "illusion transmitter," for which she received a patent in 1980
- Different Types of Holograms - holocenter
There are a number of ways of making digital holograms in which small regions of the film, termed ‘Voxels’ or ‘Hogels’, are exposed to the pre-calculated fringe pattern, such as by using a spatial light modulator (SLM) or electron beam lithography
- How holograms work - Explain that Stuff
An easy-to-understand explanation of what holograms are, how they're made, and what they can be used for
- 4. 8: Holography - Physics LibreTexts
Holography is the process of producing holograms and, although they are recorded on photographic film, the process is quite different from normal photography Holography uses light interference or wave optics, whereas normal photography uses geometric optics
- 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
- 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
