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.

Early holography required high-power and expensive lasers. Currently, mass-produced low-cost laser diodes, such as those found on DVD recorders and used in other common applications, can be used to make holograms. They have made holography much more accessible to low-budget researchers, artists, and dedicated hobbyists.
A Los Angeles company has created phone booth-sized machines to beam live holograms into your living room. The machines also can be equipped with technology to enable interaction with recorded ...
A holographic display is a type of 3D display that utilizes light diffraction to display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image, and do not cause a vergence-accommodation conflict.
Proto is the original inventor of hologram machines and the platform that makes holoportation and AI-powered spatial compute possible. The patented, 4x CES Innovation Award-winning technology is already in use around the world at Fortune 500 levels in enterprise, finance, education, healthcare, retail, hospitality, sports and entertainment and ...
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.
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] When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
