Holography is a method of generating 3D images using interference patterns of light. Learn about the history, types, and applications of holography, from electron microscopy to rainbow holograms.
The meaning of HOLOGRAM is a three-dimensional image reproduced from a pattern of interference produced by a split coherent beam of radiation (such as a laser); also : the pattern of interference itself. Did you know?
Learn how holograms create 3-D images of real objects using light, lenses and film. Find out how holograms are different from photographs and how they can be cut, moved and magnified.
To create a hologram, you need an object (or person) that you want to record; a laser beam to be shined upon the object and the recording medium; a recording medium with the proper materials ...
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 do you make a hologram? You make a hologram by reflecting a laser beam off the object you want to capture. Photo: Laser beams—the bright, perfect power behind holograms.

In fact, you split the laser beam into two separate halves by shining it through a half- mirror (a piece of glass coated with a thin layer of silver so half the laser ...
A hologram, such as the one in Figure 4.8.1 4.8. 1, 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 licenses (a laser and other equipment are needed to reproduce them); and for serious three-dimensional ...
Spanish engineers develop FlexiVol, the world's first interactive 3D hologram. Manipulate virtual objects with touch and gestures, no glasses needed.
A hologram is a three-dimensional light field that is generated via a physical recording of an interference pattern. This pattern involves a phenomenon called diffraction, which ultimately results in a virtual 3D image of the original scene.
Learn the definition and history of holography, the science of creating three-dimensional images from light diffraction. Discover the difference between holograms and other visual media that use similar techniques or effects.
