2. Physics of optical holography - Wikipedia

   en.wikipedia.org/wiki/Physics_of_Optical_Holography

   A holographic image can also be obtained using a different laser beam configuration to the original recording object beam, but the reconstructed image will not match the original exactly. [2]: Section 2.3 When a laser is used to reconstruct the hologram, the image is speckled just as the original image will have been.

3. Holography - Wikipedia

   en.wikipedia.org/wiki/Holography

   Holographic portraiture often resorts to a non-holographic intermediate imaging procedure, to avoid the dangerous high-powered pulsed lasers which would be needed to optically "freeze" moving subjects as perfectly as the extremely motion-intolerant holographic recording process requires. Early holography required high-power and expensive lasers.

4. Computer-generated holography - Wikipedia

   en.wikipedia.org/wiki/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]

5. Interference lithography - Wikipedia

   en.wikipedia.org/wiki/Interference_lithography

   Interference lithography (or holographic lithography) is a technique that uses coherent light (such as light from a laser) for patterning regular arrays of fine features without the use of complex optical systems or photomasks.

6. Holographic data storage - Wikipedia

   en.wikipedia.org/wiki/Holographic_data_storage

   Holographic data storage is a potential technology in the area of high-capacity data storage. While magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium, holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same ...

7. Holographic Versatile Disc - Wikipedia

   en.wikipedia.org/wiki/Holographic_Versatile_Disc

   The Holographic Versatile Disc (HVD) is an optical disc technology that was expected to store up to several terabytes of data on an optical disc 10 cm or 12 cm in diameter. Its development commenced in April 2004.
