  2. Security hologram - Wikipedia

    en.wikipedia.org/wiki/Security_hologram

    Security holograms are labels with a hologram printed onto it for sale security reasons. It is argued by the International Hologram Manufacturers Association that holograms on security labels are difficult to forge because they are replicated from a master hologram which requires expensive specialized and technologically advanced equipment.

  3. Computer-generated holography - Wikipedia

    en.wikipedia.org/wiki/Computer-generated_holography

    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]

  4. Holography - Wikipedia

    en.wikipedia.org/wiki/Holography

    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 .

  9. Digital holography - Wikipedia

    en.wikipedia.org/wiki/Digital_holography

    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 ...
