Today it is commonly used to study electric and magnetic fields in thin films, as magnetic and electric fields can shift the phase of the interfering wave passing through the sample. [45] The principle of electron holography can also be applied to interference lithography. [46] Acoustic holography enables sound maps of an object to be generated ...
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.

Blade Runner Style Holograms. This is why I came to CES. This is the shit I want, like the Blade Runner 2049 meme. The London-based software company Hypervsn made a splash on the Las Vegas ...
These systems have been used to produce holograms of live people. A holographic portrait of Dennis Gabor was produced in 1971 using a pulsed ruby laser. [1]: Figure 4.5, p44 [8] Thus, the laser power, recording medium sensitivity, recording time and mechanical and thermal stability requirements are all interlinked.
The term "computer-generated holography" has become used to denote the whole process chain of synthetically preparing holographic light wavefronts suitable for observation. [ 2 ] [ 3 ] If holographic data of existing objects is generated optically and recorded and processed digitally, and subsequently displayed, this is termed CGH as well.
Zebra Imaging was a company that developed 3D digital holographic images, hologram imagers and interactive 3D displays for government [1] and commercial uses. The company offers digital holograms that are autostereoscopic (no glasses or goggles required), full-parallax (viewing of the image from viewpoints above and below as well as from side to side) and in monochrome or full-color.
In August 2002 a new manufacturing unit for mastering art holograms (3-D holograms on glass) was created. In November of the same year the enterprise issued a novel product: a transparent film enhanced with holographic elements (holographic overlay) to reinforce the security of identity documents for officers of MIA of Ukraine.
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.
