  2. Security hologram - Wikipedia

    en.wikipedia.org/wiki/Security_hologram

    The technology here is similar to the technology used for the past 50 years to make red safety night reflectors for bicycles, trucks, and cars. These holograms (and therefore the artwork of these holograms) may be of two layers (i.e. with a background and a foreground) or three layers (with a background, a middle ground and a foreground).

  3. Physics of optical holography - Wikipedia

    en.wikipedia.org/wiki/Physics_of_Optical_Holography

    Physics of optical holography. Optical holography[ 1] is a technique which enables an optical wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images but it also has a wide range of other applications .

  4. Holographic weapon sight - Wikipedia

    en.wikipedia.org/wiki/Holographic_weapon_sight

    A view through an EOTech 512 holographic weapon sight. A holographic weapon sight or holographic diffraction sight is a non- magnifying gunsight that allows the user to look through a glass optical window and see a holographic reticle image superimposed at a distance on the field of view. [ 1] The hologram of the reticle is built into the ...

  5. Reflector sight - Wikipedia

    en.wikipedia.org/wiki/Reflector_sight

    A view through the Mark III Free Gun Reflector Sight, first produced in 1943, used on British army guns, naval guns, and as a pilot sight and a defensive gun sight on aircraft. The reticle image in this sight is produced by an optical collimator bounced off a beam splitter. The dot remains on the target even though the viewer's head is moved ...

    en.wikipedia.org/wiki/Holography

    Holography. Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave .

  7. Retroreflector - Wikipedia

    en.wikipedia.org/wiki/Retroreflector

    A typical surveying prism with back target. In surveying, a retroreflector—usually referred to as a prism —is normally attached on a surveying pole and is used as a target for distance measurement, for example, a total station. The instrument operator or robot aims a laser beam at the retroreflector.

  8. Digital holography - Wikipedia

    en.wikipedia.org/wiki/Digital_holography

    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. Digital holography offers a means of measuring optical phase data and typically delivers ...

  9. Telescopic sight - Wikipedia

    en.wikipedia.org/wiki/Telescopic_sight

    An early example of a man-portable sight for low visibility/night use is the Zielgerät (aiming device) 1229 (ZG 1229), also known by its code name Vampir ("vampire"). The ZG 1229 Vampir was a Generation 0 active infrared night vision device developed for the Wehrmacht for the StG 44 assault rifle, intended primarily for night use. The issuing ...
