Dot matrix holograms are capable of embedding microtext at various sizes. There are three types of microtexts in holograms: [citation needed] high contrast microtexts of size 50 – 150 micrometres; diffractive grating filled microtexts of size 50 – 150 micrometres low contrast microtexts. Microtexts of sizes smaller than 50 micrometres are ...
Holographic Versatile Card. The Holographic Versatile Card (HVC) was a proposed data storage format by Optware; the projected date for a Japanese launch had been the first half of 2007, pending finalization of the specification, however as of January 2025, nothing has yet surfaced.This issue may be related to the bankrupt of certain entities once responsible for the development and ...
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 ...
On the inner sleeve was an explanation of the holographic process and instructions on how to light the hologram. National Geographic published the first magazine with a hologram cover in March 1984. [14] Embossed holograms are used widely on credit cards, banknotes, and high value products for authentication purposes. [3]

In their January 2020 report, the International Card Manufacturers Association's (ICMA) indicates a production increase to a record-high of 37.1 billion cards and $27 billion revenue in 2019. [1] Forecasts predicted market growth at a rate of 8.2% from 2021 to 2028, which was counteracted by losses through the Covid pandemic .
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.
The objective of the test was to find a new method of measuring surface and atmospheric parameters that could reduce the size, mass, and angular momentum of a spaceborne lidar systems. [ 6 ] [ 8 ] The ability of HOE to be made as curved or bendable allows it to be used in the construction of head up displays (HUD) or head mount displays (HMD).
