'''Holography''' is a technological system that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. Holography is employed by the [[human]]s, the [[Covenant]] and the [[Forerunner]]s in a variety of functions - communications, battle and sensor displays, and as [[Type-27 Responsive Holographic Form Emulator|distractions]] and [[holo-drone|decoys]]. Devices used to project holograms are commonly referred to as [[holotank]]s.

The UNSC uses holographic technology in a variety of ways. [[Artificial intelligence]] constructs, such as [[Cortana]], project holographic representations of themselves for personal communications with humans, with each AI taking a [[Avatar|unique appearance]] of their own choice. The UNSC also uses holograms for communications between individual humans. The commanding officer of one ship may "appear" on another to deliver a message when normally access between the two vessels is restricted. Many UNSC warships, [[military base|bases]] and other facilities are equipped with holographic tables, used to project topographical maps or other images for tactical purposes.


==Overview==
Holography is frequently used in human computer terminals, which, though not actually solid, respond accordingly to physical input without the need for a separate device such as a keyboard.{{Ref/Film|H4FuD}} Holography also has many [[civilian]] uses. For example, some nightclubs such as [[Club Errera]] make extensive use of holograms.{{Ref/Level|HR|[[New Alexandria]]}} Humans also use holographic technology to display holographic "photographs", referred to as [[holo-still]]s. Holographic tape is used to display information on the sides of civilian vehicles.{{Ref/Novel|CH|Page=77}}
Holography was invented in 1947 by Hungarian physicist Dennis Gabor (1900–1979), work for which he received the Nobel Prize in physics in 1971. It was made possible by pioneering work in the field of physics by other scientists like Mieczysław Wolfke who resolved technical issues that previously made advancements impossible. The discovery was an unexpected result of research into improving electron microscopes at the British Thomson-Houston Company in Rugby, England. The British Thomson-Houston company filed a patent on 1947-12-17 (and received patent GB685286), but the field did not really advance until the development of the laser in 1960.  


The first holograms that recorded 3D objects were made by Yuri Denisyuk in the Soviet Union in 1962; later by Emmett Leith and Juris Upatnieks in University of Michigan, USA in 1962. Advances in photochemical processing techniques, to produce high-quality display holograms were achieved by Nicholas J. Phillips.
The [[MJOLNIR Powered Assault Armor (GEN3)|GEN3 MJOLNIR Powered Assault Armor]] is capable of displaying the hologram of an integrated AI over its hand to communicate directly with outside forces rather than using the armor's speakers. The AI is also capable of transferring into systems through these holographic emitters, the emitters having not been a feature of previous generations of the armor.{{Ref/Game|Hi}}

Several types of holograms can be made. Transmission holograms, such as those produced by Leith and Upatnieks, are viewed by shining laser light through them and looking at the reconstructed image from the side of the hologram opposite the source. A later refinement, the "rainbow transmission" hologram allows more convenient illumination by white light rather than by lasers or other monochromatic sources. Rainbow holograms are commonly seen today on credit cards as a security feature and on product packaging. These versions of the rainbow transmission hologram are commonly formed as surface relief patterns in a plastic film, and they incorporate a reflective aluminum coating which provides the light from "behind" to reconstruct their imagery.
===Covenant===
[[File:Broadcast2.jpg|thumb|Covenant [[San'Shyuum|Prophets]] used holographic projectors to preach to their troops.]]
The [[Covenant]]'s holographic technology is also based primarily on that of the Forerunners, and though superior to UNSC technology it still pales in comparison. The Covenant use holograms for visual displays of space and ground combat, allowing a better general view of the action and better coordination. Holograms are also used as decoys, through devices known as [[holo-drone]]s, able to generate their own shields and weapons to give the illusion of reality. One of these was used by the [[Sesa 'Refumee's heretic faction|heretic]] leader [[Sesa 'Refumee]] before his death at the hands of the [[Thel 'Vadam|Arbiter]].{{Ref/Level|H2|[[The Heretic]]}} The Covenant also utilize less sophisticated [[armor abilities#Hologram|holographic decoys]] in the field, a technology which has also been replicated by the UNSC.{{Ref/Game|HR}}


Another kind of common hologram, the reflection or Denisyuk hologram, is capable of multicolor image reproduction using a white light illumination source on the same side of the hologram as the viewer.
As shown by the ability of holo-drones to use weaponry, certain Covenant holograms are somehow capable of physically interacting with their environment. The Prophets, in particular, make extensive use of holography in their governance of the Covenant. Religious sermons, such as those by the [[Prophet of Truth]]{{Ref/Level|H3|[[Tsavo Highway]]}}{{Ref/Level|H3|[[The Storm]]}}{{Ref/Level|H3|[[The Ark (level)|The Ark]]}} {{Ref/Level|H3|[[The Covenant (level)|The Covenant]]}} and [[Prophet of Regret]],{{Ref/Level|H2|[[Delta Halo]]}}{{Ref/Level|H2|[[Regret (Halo 2 level)|Regret]]}} are transmitted holographically via [[Portable holo-pedestal|portable projectors]], allowing the Prophets to preach from the relative safety of their point of transmission while protected by [[Honor Guard|armed guards]].

What is generally, and incorrectly, referred to as a hologram in most science fiction, including the Halo series, is actually a [[Wikipedia:Volumetric display|Volumetric Display]]. true holograms are not three-dimensional images. More specifically, Halo "holograms" seem to be of the [[Wikipedia:Volumetric Display #Static Volume|Static Volume]] type, creating an actual three-dimensional image rather than creating the illusion of it.<ref>[[Wikipedia:Holography]]</ref>
===Forerunner===
[[File:Ark.JPG|thumb|A Forerunner holographic representation of the Ark.]]
Consistent with their high level of technological advancement, the long-vanished Forerunners were true masters of holography. Their projections were accurate far beyond UNSC or even Covenant capabilities, able to appear indistinguishable from physical objects and simulate solidity via the use of sophisticated [[hard light]] technology.  


===UNSC===
On the various facilities of the [[Halo Array]] as well as other Forerunner installations, holograms are used to convey information on the installation, from general visual representations to more specific details. Virtually all Forerunner control panels and terminals are based upon solid, hard light holography.

The UNSC uses holographic technology in a variety of ways. Devices used to project holograms are commonly referred to as "[[Holotank]]s". Artificial Intelligences, such as [[Cortana]], project holographic representations of themselves for personal communications with humans, with each AI taking a unique appearance of their own choice.  The UNSC also uses holograms for communications between individual humans. The commanding officer of one ship may "appear" on another to deliver a message when normally access between the two vessels is restricted. Also, holographic technology is used by the UNSC to project topographical maps for tactical purposes. This is seen in ''[[Halo Wars]]'' aboard the {{UNSCShip|Spirit of Fire}}, and in ''[[Halo 3: ODST]]'', where a rendering of [[New Mombasa]] and [[Regret's Carrier]] above it are displayed before the drop. Humans also use holographic technology in photographs, referred to as [[Holo-Still]]s.
The Forerunners also used their mastery of holography to produce realistic decoration to interior spaces; for example, the [[Menachite portal complex|Forerunner ruins]] underneath [[CASTLE Base]], despite eons of neglect, were still capable of projecting myriad environments from hundreds of worlds.

===Covenant===

The Covenant's holographic technology is also based primarily on that of the Forerunners, and though superior to UNSC technology it still pales in comparison. Covenant hologram projectors can be referred to either as Holotanks like their UNSC equivalents, or alternatively, [[Holo-Pedestal]]s. The Covenant use holograms for visual displays of space and ground combat, allowing a better general view of the action and better coordination.<ref>In the background on the [[Shadow of Intent]]</ref> Holograms are also used as decoys, through devices known as [[Holo-Drone]]s, able to generate their own shields and weapons to give the illusion of reality. One of these was used by the [[Sesa 'Refumee|Heretic Leader]] before his death at the hands of the [[Thel 'Vadam|Arbiter]].<ref>[[Halo 2]], [[The Heretic (Level)]]</ref>
The Prophets, in particular, make extensive use of holography in their governance of the Covenant. Religious sermons, such as those by the [[Prophet of Truth]]<ref>[[Halo 3]], [[Tsavo Highway (Level)]], [[The Storm (Level)]], [[The Ark (Level)]] and [[The Covenant (Level)]]</ref> and [[Prophet of Regret]]<ref>[[Halo 2]], [[Delta Halo (Level)]] and Regret (Level)</ref>, are transmitted holographically, allowing the Prophets to preach from the relative safety of their point of transmission while protected by [[Honor Guard|armed guards]].


===Forerunners===
==Trivia==
[[File:Epitaph symbol.png|100px|thumb|An enigmatic Forerunner hologram on [[Epitaph (Level)|Epitaph]].]]
{{Linkbox|gallery=yes|gallerypage=Images of hologram technology}}
Though now extinct, the Forerunners were true masters of holography. Their projections were accurate far beyond UNSC or even Covenant capabilities, able to appear as solid and actual objects. Holograms were used on Alpha Halo for a visible representation of the ringworld, and on the Ark for each of the Halo's and for a visual demonstration by 343 Guilty Spark on the Halo Array's capabilities. It is also notable to mention that many of the Forerunner terminals and nodes that can be activated, particularly in Halo 3, as holograms, yet apparently feel solid and can be pressed by the Master Chief. This could just be him passing his hand over the hologram, but in-game he appears to actually touch them. If this is so, then the Forerunner were also capable of producing "Hard Light" a type material made of photons so compact that they form a solid object. Either way, they are truly magnificent feats of engineering.

A holographic topographical map and the avatar of AI Serina aboard a UNSC warship, the UNSC Spirit of Fire.

Holography is a technological system that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. Holography is employed by the humans, the Covenant and the Forerunners in a variety of functions - communications, battle and sensor displays, and as distractions and decoys. Devices used to project holograms are commonly referred to as holotanks.

Applications[edit]

Human[edit]

An example of civilian application of holography in Club Errera.

The UNSC uses holographic technology in a variety of ways. Artificial intelligence constructs, such as Cortana, project holographic representations of themselves for personal communications with humans, with each AI taking a unique appearance of their own choice. The UNSC also uses holograms for communications between individual humans. The commanding officer of one ship may "appear" on another to deliver a message when normally access between the two vessels is restricted. Many UNSC warships, bases and other facilities are equipped with holographic tables, used to project topographical maps or other images for tactical purposes.

Holography is frequently used in human computer terminals, which, though not actually solid, respond accordingly to physical input without the need for a separate device such as a keyboard.[1] Holography also has many civilian uses. For example, some nightclubs such as Club Errera make extensive use of holograms.[2] Humans also use holographic technology to display holographic "photographs", referred to as holo-stills. Holographic tape is used to display information on the sides of civilian vehicles.[3]

The GEN3 MJOLNIR Powered Assault Armor is capable of displaying the hologram of an integrated AI over its hand to communicate directly with outside forces rather than using the armor's speakers. The AI is also capable of transferring into systems through these holographic emitters, the emitters having not been a feature of previous generations of the armor.[4]

Covenant[edit]

Covenant Prophets used holographic projectors to preach to their troops.

The Covenant's holographic technology is also based primarily on that of the Forerunners, and though superior to UNSC technology it still pales in comparison. The Covenant use holograms for visual displays of space and ground combat, allowing a better general view of the action and better coordination. Holograms are also used as decoys, through devices known as holo-drones, able to generate their own shields and weapons to give the illusion of reality. One of these was used by the heretic leader Sesa 'Refumee before his death at the hands of the Arbiter.[5] The Covenant also utilize less sophisticated holographic decoys in the field, a technology which has also been replicated by the UNSC.[6]

As shown by the ability of holo-drones to use weaponry, certain Covenant holograms are somehow capable of physically interacting with their environment. The Prophets, in particular, make extensive use of holography in their governance of the Covenant. Religious sermons, such as those by the Prophet of Truth[7][8][9] [10] and Prophet of Regret,[11][12] are transmitted holographically via portable projectors, allowing the Prophets to preach from the relative safety of their point of transmission while protected by armed guards.

Forerunner[edit]

A Forerunner holographic representation of the Ark.

Consistent with their high level of technological advancement, the long-vanished Forerunners were true masters of holography. Their projections were accurate far beyond UNSC or even Covenant capabilities, able to appear indistinguishable from physical objects and simulate solidity via the use of sophisticated hard light technology.

On the various facilities of the Halo Array as well as other Forerunner installations, holograms are used to convey information on the installation, from general visual representations to more specific details. Virtually all Forerunner control panels and terminals are based upon solid, hard light holography.

The Forerunners also used their mastery of holography to produce realistic decoration to interior spaces; for example, the Forerunner ruins underneath CASTLE Base, despite eons of neglect, were still capable of projecting myriad environments from hundreds of worlds.

What is generally, and incorrectly, referred to as a "hologram" in most science fiction, including the Halo series, is actually a volumetric display. True holograms are not three-dimensional images. More specifically, Halo "holograms" seem to be of the static volume type, creating an actual three-dimensional image rather than creating the illusion of it.[13]
