  3. Physics of optical holography - Wikipedia

    en.wikipedia.org/wiki/Physics_of_Optical_Holography

    When the hologram plate is illuminated by a laser beam identical to the reference beam which was used to record the hologram, an exact reconstruction of the original object wavefront is obtained. An imaging system (an eye or a camera) located in the reconstructed beam 'sees' exactly the same scene as it would have done when viewing the original.

  4. Holography - Wikipedia

    en.wikipedia.org/wiki/Holography

    The hologram keeps the information on the amplitude and phase of the field. Several holograms may keep information about the same distribution of light, emitted to various directions. The numerical analysis of such holograms allows one to emulate large numerical aperture, which, in turn, enables enhancement of the resolution of optical microscopy.

  5. Photorefractive effect - Wikipedia

    en.wikipedia.org/wiki/Photorefractive_effect

    For example, in the case of a hologram, illuminating the grating with just the reference beam causes the reconstruction of the original signal beam. When two coherent laser beams (usually obtained by splitting a laser beam by the use of a beamsplitter into two, and then suitably redirecting by mirrors ) cross inside a photorefractive crystal ...
