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]
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 .
Digital holography is the acquisition and processing of holograms with a digital sensor array, [ 1][ 2] typically a CCD camera or a similar device. Image rendering, or reconstruction of object data is performed numerically from digitized interferograms. Digital holography offers a means of measuring optical phase data and typically delivers ...
From the mid-19th century, the illusion, today known as Pepper's Ghost, became widely developed for money-making stage entertainments, amid bitter argument, patent disputes, and legal action concerning the technique's authorship. A popular genre of entertainment was stage demonstrations of scientific novelties.
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 .
Digital planar holography (DPH) is a method for designing and fabricating miniature components for integrated optics. It was invented by Vladimir Yankov and first published in 2003. [1] [2] The essence of the DPH technology is embedding computer designed digital holograms inside a planar waveguide. Light propagates through the plane of the ...
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 ...
A Hologram for the King is a 2016 comedy-drama film written, directed and co-scored by Tom Tykwer, based on the 2012 novel of the same name written by Dave Eggers, [ 7][ 8] and starring Tom Hanks as a washed-up corporate salesman, who goes to Saudi Arabia to propose a business deal. Sidse Babett Knudsen, Tom Skerritt and Sarita Choudhury also ...
