    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).

    This dimension refers to the subrack in which the card is to be mounted, rather than the card itself. A single card is 100 mm high. Taller cards add a 133.35 mm, so that a double height card is 233.35 mm high and a triple 366.7 mm high. Enclosure heights are multiples of 3U, with the cards always 33.35 mm (1.313 in) shorter than the enclosure.

    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 .

    en.wikipedia.org/wiki/Security_hologram

    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 ...

    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]

  8. Holographic display - Wikipedia

    en.wikipedia.org/wiki/Holographic_display

    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.
