Holography. Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave .
Physics of optical holography. Optical holography[ 1] is a technique which enables an optical wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images but it also has a wide range of other applications .
Computer-generated holography. Computer-generated holography ( CGH) is a technique that uses computer algorithms to generate holograms. It involves generating holographic interference patterns. A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography. [ 1]
An example that combines the Pepper's ghost effect with a live actor and film projection can be seen in the Mystery Lodge exhibit at the Knott's Berry Farm theme park in Buena Park, California, and the Ghosts of the Library exhibit at the Abraham Lincoln Presidential Library and Museum in Springfield, Illinois, as well as the depiction of Maori ...
He deliberately worked direct references in the poem into the script for the episode, such as specific lines and the attack on the mead hall. [4] His significant change from Beowulf was the addition of the character, Freya. [2] The script went through two drafting stages, with the main issue being the alien element rather than the Viking details.
Holographic interferometry. Holographic interferometry ( HI) [1] [2] is a technique which enables the measurements of static and dynamic displacements of objects with optically rough surfaces at optical interferometric precision (i.e. to fractions of a wavelength of light). These measurements can be applied to stress, strain and vibration ...
Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction. HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies. The shape and structure of the HOE is dependent on the piece of hardware it is ...
Holographic display. A holographic display is a type of 3D display that utilizes light diffraction to display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image ...
