Holography Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics.n principle, it is possible to make a hologram for any wave. Electron holography is the application of holography techniques to electron waves rather than light waves. Electron holography was invented by Dennis Gabor to improve the resolution and avoid the aberrations of the transmission electron microscope.

Holography An amplitude modulation hologram is one where the amplitude of light diffracted by the hologram is proportional to the intensity of the recorded light. A straightforward example of this is photographic emulsion on a transparent substrate.

Holographic display Holographic display. A holographic display is a type of display that utilizes light diffraction to create a virtual three-dimensional image of an object. Holographic displays are unique from other forms of 3D imaging in that they do not require the aid of any special glasses or external equipment for a viewer to see the image.

What is a hologram? Give a voice command to a hologram, and it can reply. Holograms enable personal interactions that aren't possible elsewhere. Because the HoloLens knows where it is in the world, a holographic character can look you directly in the eyes as you walk around the room. A hologram can also interact with your surroundings.

Holographic display 1947 - Hungarian scientist Dennis Gabor first came up with the concept of a hologram while trying to improve the resolution of electron microscopes. He derived the name for holography, with holos being the Greek word for whole, and gramma which is the term for message.

Holographic optical element One use of a holographic optical element is in thin-profile combiner lenses for optical head-mounted displays. A reflective volume hologram is used to extract progressively a collimated image that was directed via total internal reflection in an optical waveguide.

Electroencephalography (EEG) The electroencephalogram (EEG) is a measure of brain waves. It is a readily available test that provides evidence of how the brain functions over time. 1  The EEG is used in the evaluation of brain disorders. 2  Most commonly it is used to show the type and location of the activity in the brain during a seizure.

Microsoft has created Star Wars-style holographic communication Microsoft's I3D research group has figured out how to create a live hologram of another person to be placed in another room. A massive array of 3D cameras in one room captures an entire person's movements and speech in real time, then projects them into another room where a HoloLens user can see them and interact with them.

- The image at upper right is the view through the larger part of the hologram, while that at lower right is through a small corner cut off the hologram. While the view through the small corner is from a particular point of view, it contains the whole object.

- Driving Directions. EEG, or electroencephalogram, is a tool we use to image the brain while it is performing a cognitive task. This allows us to detect the location and magnitude of brain activity involved in the various types of cognitive functions we study.

Hoist (device) From Wikipedia, the free encyclopedia. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.

Holography The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of seemingly random variations in the opacity, density, or surface profile of the photographic medium.

- (November 2011) Horology (via Latin horologium from Greek ὡρολόγιον, from ὥρα hṓra hour; time and -o- interfix and suffix -logy; literally the study of time) is the art and/or science of measuring time. Ancient Sanskrit language has a similar word hora (होरा) meaning hour. This word is also used as a measurement of time.

What is a Hologram? Various types of holograms have been made over the years, including transmission holograms, which allow light to be shined through them and the image to be viewed from the side; and rainbow holograms, which are used for security purposes — on credit cards and driver's licenses, for example.

Electroencephalography --EEG Electroencephalography --EEG. Electroencephalography is the neurophysiologic measurement of the electrical activity of the brain by recording from electrodes placed to the scalp, or in the special cases on the cortex. The resulting traces are known as an electroencephalogram (EEG) and represent so-called brainwaves.
