2. Physics of optical holography - Wikipedia

   en.wikipedia.org/wiki/Physics_of_Optical_Holography

   A phase hologram [3]: Section 3.7 is made by changing either the thickness or the refractive index of the material in proportion to the intensity of the holographic interference pattern. This is a phase grating and it can be shown that when such a plate is illuminated by the original reference beam, it reconstructs the original object wavefront.

3. Holography - Wikipedia

   A Pepper's ghost illusion made from a clear plastic frustum Shows making using of projected images are erroneously marketed as "holographic" There are many optical effects that are falsely confused with holography, such as the effects produced by lenticular printing , the Pepper's ghost illusion (or modern variants such as the Musion Eyeliner ...

4. Holographic optical element - Wikipedia

   en.wikipedia.org/wiki/Holographic_optical_element

   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.

5. Microhologram - Wikipedia

   en.wikipedia.org/wiki/Microhologram

   Connecting of a hologram with the protected item is a critical task, and there are many specific technologies for it. Microholograms enable to protect material (substrate)l for a production of documents, stamps, products, etc. Tiny metallic particles of the size from 40 micrometers to half a millimeter are blended into plastic, paper, foil, etc.

6. Holographic grating - Wikipedia

   Nevertheless, the lower limit over the grating spacing is one order of magnitude smaller than the latter. Their availability, low cost, and versatility opened the path for their use in a various range of applications such as data storage, [3] holographic display [4] [5] and in general, as holographic optical components.

7. Heat transfer vinyl - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer_vinyl

   Heat transfer vinyl cannot be used for full-color pictures or anything with gradients. There are other applications for those options. Heat transfer vinyl can be used to create special effects with its glitter, flocked, holographic, glow-in-the-dark, and 3D puff options. The layering of these types of vinyl is dependent on the type of vinyl used.
