A three-dimensional image of an object made by holography. Did You Know? If you tear an ordinary photograph in two, each piece shows only a part of the original image.
If you break a hologram in two, however, you end up with two holograms, each of which shows the entire original scene, although from slightly different points of view. That's because each spot on a hologram contains enough information to show how the entire scene would look if it were viewed from a particular vantage point.
Imagine looking at a room through a peephole set in a solid door. What you see depends on where in the door the peephole is placed. Each piece of the hologram is a "peephole" view, and that's what makes the image look three-dimensional: as you move the hologram around or look at different parts of it, you see the original object from different angles, just as if it were a truly three-dimensional object and you were walking around it.
The amount of information contained in holograms makes them very useful. They are much harder to copy than simple two-dimensional images, since to forge a hologram you'd have to know what the original object looked like from many angles.
That's why credit cards, CDs, sports memorabilia, and other items include holographic stickers as indicators of authenticity. Copyright The Gale Group, Inc. Switch to new thesaurus.

Real holograms come closer to reality with hologram TVs. An international collection of holograms will be on display at Rugby Art Gallery and Museum in Rugby - the home of the hologram - as part of a national tour.
Since GSK first used a tamper evident hologram to seal packs of Zantac inholograms have been taken up in a big way by the industry. Holograms have anti-counterfeiting function: Ian Lancaster of the IHMA International Hologram Manufacturers' Association describes how holograms continue to successfully overcome counterfeiting problems in the pharmaceutical industry.

The ghost of Michael Jackson? Either way, these holographic concerts are a step in the right direction. A reflective pane of glass is set on a stage and angled down toward a hidden booth. When the hidden booth is illuminated, it reflects an image onto the pane of glass, which then reflects the image toward the audience. At eye level, this image would look squished remember, the glass is angled. Last time we checked, Michael Jackson was dead, so we can assume the technology has changed a bit, right?
Rather than relying on secret rooms, actors, and glass to project humans onto a stage, the Musion Eyeliner trick simply requires a projector and a thin mylar sheet. First, the mylar sheet is placed at the front of a stage at a degree angle. Then, a projector in front of the stage shoots an image at the mylar sheet. There also needs to be a source video for these projections.
Ideally, the source video is completely still, creating the illusion that a performer is on the stage. This can be done by recording a performance with a still camera, or by creating an expensive 3D model and then rigging it to sing and dance the Tupac, Jackson, and Roy Orbison holograms are 3D models. Aside from obvious ethical dilemmas, Musion Eyeliner has a lot of technological shortcomings and vulnerabilities:. Right now, most of your favorite electronics corporations are spending oodles of money on augmented reality.

We work for top brands across the globe.A hologram is a real world recording of an interference pattern which uses diffraction to reproduce a 3D light field, resulting in an image which still has the depth, parallaxand other properties of the original scene.
A hologram is a photographic recording of a light fieldrather than an image formed by a lens. The holographic medium, for example the object produced by a holographic process which may be referred to as a hologram is usually unintelligible when viewed under diffuse ambient light.
It is an encoding of the light field as an interference pattern of variations in the opacitydensityor surface profile of the photographic medium.
When suitably lit, the interference pattern diffracts the light into an accurate reproduction of the original light field, and the objects that were in it exhibit visual depth cues such as parallax and perspective that change realistically with the different angles of viewing. That is, the view of the image from different angles represents the subject viewed from similar angles. In this sense, holograms do not have just the illusion of depth but are truly three-dimensional images.
In its pure form, holography needs a laser light for illuminating the subject and for viewing the finished hologram. A microscopic level of detail throughout the recorded scene can be reproduced. In common practice, however, major image quality compromises are made to remove the need for laser illumination to view the hologram, and in some cases, to make it.
Holographic portraiture often resorts to a non-holographic intermediate imaging procedure, to avoid the dangerous high-powered pulsed lasers which would be needed to optically "freeze" moving subjects as perfectly as the extremely motion-intolerant holographic recording process requires.
Holograms can now also be entirely computer-generated to show objects or scenes that never existed. Holography is distinct from lenticular and other earlier autostereoscopic 3D display technologies, which can produce superficially similar results but are based on conventional lens imaging.
Images requiring the aid of special glasses or other intermediate opticsstage illusions such as Pepper's Ghost and other unusual, baffling, or seemingly magical images are often incorrectly called holograms. Dennis Gabor invented holography in and later won a Nobel Prize for his efforts. The technique as originally invented is still used in electron microscopywhere it is known as electron holographybut optical holography did not really advance until the development of the laser in They were not very efficient as the produced grating absorbed much of the incident light.
Various methods of converting the variation in transmission to a variation in refractive index known as "bleaching" were developed which enabled much more efficient holograms to be produced. Several types of holograms can be made. Transmission holograms, such as those produced by Leith and Upatnieks, are viewed by shining laser light through them and looking at the reconstructed image from the side of the hologram opposite the source. Another kind of common hologram, the reflection or Denisyuk hologram, can also be viewed using a white-light illumination source on the same side of the hologram as the viewer and is the type of hologram normally seen in holographic displays.
They are also capable of multicolour-image reproduction. Specular holography is a related technique for making three-dimensional images by controlling the motion of specularities on a two-dimensional surface.
