[[caption-width-right:311:Transmit galaxy-wide live 3D? No problem. Use colors other than blue? [[HologramProjectionImperfection Not so much]].]]

A staple of SpeculativeFiction. Holograms can be created by technological, magical, or psychic means, but are always intangible illusions meant to fool onlookers into seeing something that isn't there. Holograms are thus the preferred tool of the TricksterArchetype and more specifically the MasterOfIllusion.

Holograms have a variety of uses, among them being deception, creating a HolographicTerminal, a simulacrum of those long dead or artificial intelligences. The exact nature and properties of holograms vary between works, but for purposes of trope differentiation and practicality, the one unifying trait they share is intangibility. If they ''do'' have substance, they're HardLight.

What media commonly identifies as a hologram is not actually a [[http://en.wikipedia.org/wiki/Holography hologram]], it's a [[http://en.wikipedia.org/wiki/Volumetric_display volumetric display]]. Actual holograms are 3D images on 2D surfaces, and ''not'' visible from arbitrary angle. While this may seem like picking nits, there are perfectly valid reasons for the practice: "hologram" is easier to say than "volumetric display," and would the BBC allow [[Series/RedDwarf Rimmer]] to walk around with "VD" plastered on his forehead?

'''Among their possible traits are:'''
* '''Opacity:''' Some are see through, others can actually block light from passing through them like a real object. Oddly, this doesn't necessarily mean they cast shadows.
* '''Emitter:''' Though common, many eschew this entirely. Instead of an emitter all you need is a powerful enough computer or piece of {{Phlebotinum}} with a monitor to make a hologram. If they do have an emitter, it will almost invariably be a DataCrystal or PowerCrystal.
* '''Range:''' Usually it's unlimited. Only rarely are they limited to a line of sight to their emitter, frequently they act as independent autonomous beings so long as the device is on, no matter how far they go or if there are objects in between.
* '''GlamourFailure:''' Despite often being the photonic equivalent of DeceptivelyHumanRobots, they will [[UncannyValley exhibit signs of being artificial]] because they: don't cast shadows, hair or clothes won't flap in the wind, are "too simple," or are not rendered very realistically.
* '''Stuttering and Static:''' Related to GlamourFailure, holgrams generally [[HologramProjectionImperfection fizz, pop, stutter and show other signs of malfunctioning]] right out of the box, though, for some reason, none of the users ever seems to notice this. For examples see HologramProjectionImperfection.
* '''Clipping:''' Because they're intangible, people and objects can and will (hilariously) pass through them. Some holograms might have a "rendering failure" while so abused and go static-y, others might simply act annoyed, and some will gleefully stick their heads through walls like ghosts to see what's on the other side. Again, don't expect interposed objects to affect the emitter.
* '''Integrated Speakers:''' One fun aspect of holograms is that they can actually speak or make noise, regardless of being unable to affect air or matter directly. This isn't a big deal for indoor or emitter-bound holograms, since it's not a big stretch to imagine there's also a speaker system hidden nearby. This is usually something that falls into WillingSuspensionOfDisbelief for unbound holograms though, since a holographic female computer avatar holding up an Etch-a-Sketch with her dialogue would be too funny.
* '''Integrated Camera:''' A hologram AI or projected image of another person can usually see through the hologram's eyes, regardless of if a camera installed near the emitter would be limited in what it can see. It's usually understood that holographic technology can somehow not just project light but "[[ScreensAreCameras see]]" everything in its vicinity.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* ''Anime/CowboyBebop'' episode "Pierrot Le Fou". While fighting Mad Pierrot/Tongpu in the Space Land amusement park, Spike goes through a door into an area forbidden to customers. A hologram of a flying cherub appears, repeatedly telling him "It's not safe in here! Let's play outside" to try to get him to leave.
* Used quite often in the later ''SuperDimensionFortressMacross'' series, usually in combination with {{Idol Singer}}s:
** In ''MacrossPlus'', the virtual idol Sharon Apple (whose processor unit is a [[Film/TwoThousandOneASpaceOdyssey HAL]]-[[ShoutOut like]] black metal box with an eye) can only "manifest" to her audience as endlessly-customizable holographic avatars. By the end of the OAV, Sharon [[spoiler:has taken control of the Macross itself, and she projects thousands and thousands of dreamlike holograms all across Macross City... as well as a titanic version of herself that envelops the titular [[HumongousMecha mecha]]]].
** In ''MacrossFrontier'', [[TheOjou Sheryl Nome]] typically performs her songs wearing a full-body holo-suit onto which a variety of costumes are projected (from the {{Stripperiffic}} to the [[PimpedOutDress regal]] ones.) Despite their nature, these holographic costumes have some level of solidity, as they can interact with the environment and vice versa.
*** In a ShoutOut to the ''MacrossPlus'' example, the climax of the series shows [[spoiler:a gigantic hologram of Ranka Lee manifesting above the Vajra homeworld, depleting the [[FunWithAcronyms NUNS]] pilots' morale and dropping the Frontier's populace into despair...]] [[spoiler:and also disguising the [[HumongousMecha Battle Galaxy]] under [[BigBad Grace's]] command]]. This hologram is disrupted when the Macross Quarter fires its [[WaveMotionGun Heavy Quantuum Cannon]] at it.
* Ladonia in ''Manga/AxisPowersHetalia'', who lives in {{Cyberspace}} (and possibly also in Sweden) and only has a physical form as long as his laptop is turned on (and sometimes not even then).
[[/folder]]

[[folder:Comics]]
* The SpiderMan villain Mysterio frequently uses holograms.
* When Creator/AlanMoore's ComicBook/TomStrong travelled to Terra Obscura, he encountered DarkAge VirtualGhost The Terror.
-->'''Tom Strong''': "The lasers aren't aimed at us. They're creating a criss-cross lattice of beams in the chamber's center. On my world, I've heard rumours of technology like this. Apparently, when two powerful lasers cross beams, it can create a hovering plasma ball... except this is ''scores'' of lasers. Properly manipulated, the plasma can emit almost intelligible sounds. They call the technology 'God's voice'..."
* In one of ComicBook/YokoTsuno's stories, "The Prey And The Shadow", [[spoiler: a girl named Margaret is forced to become the model for one of these, for reasons that her boss won't disclose. Fearing for her life and that of another girl whom she's impersonated, Margaret decides to latch on the titular ActionGirl for help... and she's got good reasons, since the hologram's a part of a cruel EvilPlan to get the other girl killed.]]
* Nightcrawler of the ComicBook/{{X-Men}} has a device that creates a hologram to let him appear normal, but he rarely uses it.
[[/folder]]

[[folder:Fan Fiction]]
* Hound is famous for his hologramming ability in ''[[http://www.tfw2005.com/boards/transformers-fan-fiction/828948-transformers-meta.html Transformers Meta]]''.
* In FanFic/WhenThereWasATomorrow, [[VideoGame/HaloReach Noble Six]] fools Covenant soldiers with this hologram distraction several times. In a ShoutOut to ''Film/TotalRecall1990'', the last "hologram" asks some confused Covenant soldiers if they really think it's him, causing them to hesitate. [[OhCrap It's him all right]].
* Magical holograms exist in ''Fanfic/EmpathTheLuckiestSmurf'', with the Imaginarium being a fantasy version of ''Franchise/StarTrek'' holodecks.
[[/folder]]

[[folder:Film]]
* ''TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension'': The black Lectroid leader sends Buckaroo a record player-like device that generates a hologram of herself.
* ''IronMan'': Tony Stark has created a holographic drafting table that he uses to design his armor in 3D (aided by his MagicalComputer butler). He can even "wear" the hologram by sticking his arms in.
** A similar holographic design system appears momentarily in CloudyWithAChanceOfMeatballs.
* ''TheLastStarfighter'': The images Zur projected into the Starfighter base.
* ''Film/{{Outland}}'': Naked holographic women dance/copulate? in the bar used by the miners.
* ''Film/ResidentEvil'': the Red Queen's projected "little girl" image.
* IRobot: Dr Lanning uses a holo-mitter to speak to Detective Spooner after his 'suicide'.
--> '''Lanning:''' I'm sorry, my responses are limited. You must ask the right questions.
* ''[[Film/ANewHope Star Wars Episode IV: A New Hope]]'': Princess Leia's image projected out of R2-D2, and the chess pieces in the game between R2-D2 and Chewbacca.
** You can see the evolution of the technology over the course of all six films. In the prequels, holograms are almost exclusively rendered in varying shades of blue. By the time of the original trilogy, they're in color, and much larger (see Vader's massive hologram of the Emperor in ''The Empire Strikes Back'', and R2's larger-than-life hologram of Luke in ''Return of the Jedi'').
* ''Film/SupermanII''
** Lex Luthor creates a laser hologram device to project images of himself and Otis playing chess. This fools the guards so they can escape Metropolis Prison.
** While Superman is talking to the computerized image of his mother Lara in his Fortress of Solitude, her image steps out of the crystal and moves around.
* In ''{{Flubber}}'' the robot Weebo projects a holographic hot girl avatar for herself to fondle the main character in his sleep. It's weirder in context.
* ''Futureworld'' (sequel to ''Film/{{Westworld}}''). Two Delos guests play a chess game using holographic pieces.
* ''Film/MinorityReport'' includes a scene with a holographic projection of a home movie. The film uses an interesting effect wherein the hologram only has partial depth and is not entirely three dimensional. It is not explained whether this is due to imperfect technology or the fact that the 3D hologram is trying to render from a 2D original.
* ''Film/TankGirl''. Kesslee's head after his operation.
* The original ''Film/TotalRecall1990'' has a device to create a photo realistic hologram that mimics the user. It is used late in the film to trick a bunch of armed guards. There's also a tennis-training hologram that Lori uses to practice her serve.
* ''Film/GIJoeTheRiseOfCobra''. When Duke first meets the Joes they have a device that projects a holographic image of their commander General Hawk.
* ''Film/LogansRun''. In the scene where Logan is interrogated about Sanctuary, the main computer creates holograms of his head that express his thoughts.
* ''Film/TheMatrix''. The bridge of the Nebuchadnezzar (and presumably the other hoverships) has a holographic display that shows other objects (like Sentinels).
* ''Film/TheWhispererInDarkness'', made in the {{retraux}} style of a 1930's UniversalHorror film, has the protagonist hooking a machine up to a BrainInAJar and saying he's not going to be fooled by some parlour trick with a radio, only to be stunned to see a HugeHolographicHead talking back to him.
* The whole plot of ''PixelPerfect'' revolves around Roscoe creating a holographic lead singer for his friends' band.
* ''FinalFantasyTheSpiritsWithin'' used holograms for computer interfaces of all kinds, even keyboards. This led to an awkward moment late in the film when the facility that a group of RedShirts are in loses power, leaving the workers stuck at workstations suspended over an open area when the keyboards vanished. [[spoiler:It also left them as sitting ducks when the Phantoms attacked]].
[[/folder]]

[[folder:Literature]]
* Used to safely simulate monsters, enemy soldiers, weapons and other threats in ''Literature/DreamPark'' and its sequels.
* In ''{{Neuromancer}}'', the character Riviera is a showman with the ability to project holograms due to having an emitter implanted in his chest. He has a taste for guro-type shows when onstage, and offstage he's no better. For example, he likes to amplify his experiences in drug use by projecting a scorpion over his hypodermic while shooting up-and to create traffic accidents by projecting the scorpion onto the dashboards of passing vehicles and hoping the driver panics. It is also his ChekhovsGun although firing it doesn't quite get the result he was hoping for. [[spoiler: the other characters recognize immediately that a hologram is a controlled laser, and could be used as a laser weapon just strong enough to [[EyeScream fry a retina over-easy, as the Finn puts it]]. Riviera eventually uses it as such against the ninja bodyguard Hideo. Unfortunately for Riviera, ninjas are quite skilled at enduring pain and fighting in the dark, so this serves only to make Hideo want to kill Riviera.]]
* ''Literature/ReturnFromTheStars'' has holographic "photos" (a flat piece of paper which displays a holographic face above when unfolded) as well as holographic theatre. [[FishOutOfTemporalWater The protagonist]] blunders into one such a spectacle, thinking it to be a gathering of real people and attempts to ask the actors for directions before realizing what a spectacle he has just made of himself.
* A commonly used ability of the Chee in ''Literature/{{Animorphs}}'', both the books and TV series. The Chee are androids who pass in human society with human holograms. They often project holograms to hide conversations with the Animorphs, or in at least one book, hide the kids' escapes with their parents.
* The central atrium of the Prometheus Corporationís HQ in TheChroniclesOfProfessorJackBaling has an enormous hologram of Prometheus as its centerpiece.
[[/folder]]

[[folder:Live Action TV]]
* ''Franchise/StarTrek'' in all its incarnations. Of special mention are the Holodecks in ''Series/StarTrekTheNextGeneration'' and [[EveryoneCallsHimBarkeep The Doctor]] in ''Series/StarTrekVoyager.''
** Ironically with all their Phlebotinum these both of those neatly avoid a few common problems. The holodecks are self-contained (so they have speakers and can "see" everything) and the doctor uses a mobile emitter.
* Al from ''Series/QuantumLeap''.
* Rimmer in Series/RedDwarf.
* Becoming implausibly common on present-day detective procedurals, including ''Series/{{Bones}}'' and ''CSINewYork''. Most police departments can barely afford toner for copiers, yet the lab rats still get ''this'' to play with?
** ''Series/{{Bones}}'' did eventually phase out the absurd holographic rendering device (and it's been lampshaded that the [[FictionalCounterpart Jeffersonian Institute]] has much nicer equipment than your average police station).
*** There is actually a way to project an image mid air like this, though it requires lasers so powerful they'd start fires. The process also (sometimes) produces gasses that might turn the fluid in your eyes to acid.
* One incarnation of ''Series/{{Andromeda}}'' (the Spaceship's Persona) is a hologram.
* ''Series/StargateSG1'' seems to regard holograms as being pretty high up the [[TechnologyLevels technological tree]], as full on holograms are the exclusive province of the Ancients and Asgard. Late on [[BigBad Anubis]] steals the plans, along with some other Asgard goodies. To what use does he put this technology? As an [[MundaneUtility interstellar telephone]] with which to [[EvilGloating taunt his enemies]], of course!
* In ''Series/RobocopTheSeries'', Diana, a secretary whose memory was uploaded into the OCP supercomputer after she was killed, could project an image of herself in a hologram.
* Actual holograms (as in, not volumetric displays) show up a handful of times in [[Series/BabylonFive Babylon 5]] as part of a Minbari fleet commander's standard equipment. Basically the displays fold down around the command staff and then the (flat) screens display fully 3D images of the battle around them.
** The technomages play the trope straight, creating volumetric displays with no visible emitters, possibly crossing the line into HardLight.
* ''Series/MissionImpossible'' has concealed hologram projectors as part of the team's arsenal since the later seasons in the 60s series. The 80s revival uses them even more frequently and even has an episode named after the trope.
[[/folder]]

[[folder:Pinball]]
* Williams' and Bally's "[[{{Trope 2000}} Pinball 2000]]" platform used a mirrored glass to display animations, scores, and other information from a computer monitor onto the {{Pinball}} playfield, for a psuedo-holographic effect. Only two pinball machines were released on this system before the company closed: ''Pinball/RevengeFromMars'' and ''Pinball/StarWarsEpisodeI''.
* ''Pinball/CreatureFromTheBlackLagoon'' used a holographic creature in the middle of the playfield that lights up and waves its "hand" back and forth during multiball.
[[/folder]]

[[folder:Tabletop RPG]]
* ''TabletopGame/CallOfCthulhu'' supplement ''The Fungi from Yuggoth''. The Yithian Communicator is a device the Yithians of the distant past use to communicate through time. The device has a red jewel that projects an image (presumably using laser light) of the Yithian itself.
* ''DungeonsAndDragons''. The Judges Guild supplement ''Wilderlands of the Magic Realm'' had an high tech artifact in the shape of a boulder that was powered by geothermal energy. It projected a laser hologram of an elven princess.
* Iron Crown Enterprises ''TabletopGame/{{Cyberspace}}'' main rules. Several high tech items can generate holograms.
** Electra brand holoclothes are exactly what they sound like: they consist entirely of a holographic image of clothes created by a belt-worn generator over the user's naked body. Better hope the batteries don't run down and the device doesn't malfunction (one known flaw is for the clothes to remain in a chair after the wearer gets up and walks away).
** Holojewelry is a small holographic projector mounted on the wearer's body. It can create images such as false faces, masks, dancing flames and swirling mists of color.
** Holovision is a device that can project three dimensional images. They can display TV shows, games or other forms of entertainment.
* Classic ''TabletopGame/{{Traveller}}''
** Adventure 2 ''Research Station Gamma''. One room in the station has a hologram of a constantly rippling waterfall on one wall.
** Adventure 3 ''Twilight's Peak''. In the Ancient base, when a gold wall patch is touched a section of wall opens and a holographic image of food appears. If the image is grabbed, the food will be teleported into the person's hand.
[[/folder]]

[[folder:Video Games]]
* Used very often in the ''MetroidPrime'' series. Planets are commonly projected for navigation purposes and in the Aurora Units frequently relay messages in this form.
* Cortana from the ''Franchise/{{Halo}}'' franchise is a holographic AI in the image of a woman. VideoGame/HaloReach and VideoGame/{{Halo 4}} also feature holograms you can deploy to distract your enemies, though some of said enemies also have this technology by the latter game.
* In ''DestroyAllHumans'', Crypto's commander, Orthopox, uses a holographic projector called a Holo Pox Unit to communicate with Crypto from the mothership.
* Sega's ''TimeTraveller'' notoriously claimed to be a hologram game when it wasn't--it was basically a flat image suspended in midair using mirrors.
* Holograms in ''The Crystal Key'' look and act exactly like the ones from the ''StarWars'' franchise (fittingly for a game where the villain is obviously meant to be Darth Vader.) They're all {{Apocalyptic Log}}s, and they're your primary source of backstory given that [[BeautifulVoid what few sentient beings are still alive]] are all working for the villain and trying to kill you.
* In ''AceAttorneyInvestigations'' Kay's 'Little Thief' computer was used to project holographic recreations of crime scenes.
* Ridiculously common in ''Franchise/DeadSpace'', your characters inventory, access panels, even ''lift buttons'' are holograms projected on to thin air. Curiously all videos are 2D and limited to the colour blue.
* ''Franchise/MassEffect'' has holograms for VI interfaces and communication. They are usually limited to a single colour at one time.
* Franchise/AssassinsCreed:
** ''VideoGame/AssassinsCreedII'' features one [[spoiler:in 1499 under the Vatican, manned by [[VideoWill Minerva]]]].
** ''VideoGame/AssassinsCreedBrotherhood'' has several [[spoiler:under the Colosseum in Rome, manned by Juno, though only Desmond can see and hear them. [[PeoplePuppets she's more direct in how she operates]]]].
** ''VideoGame/AssassinsCreedIII'' has [[spoiler:several within the Grand Temple, all showing different ways to try to avert the First Disaster, and another interface in the center of said Temple... [[NotQuiteDead though it turns out the holograms aren't just holograms]] after all, including both [[ShootTheDog Minerva]] and [[HannibalHasAPoint Juno]] this time]].
* During the Space phase of ''{{Spore}}'', players can buy a hologram emitter that will project a representation of the ship's Captain onto a planet's surface. Anything the hologram "grabs" is transported into the ship's hold.
* After beating ''VideoGame/MegaMan2's'' Alien Wily, the hologram projector broke and it was revealed the real Dr. Wily was controlling it.
** In ''VideoGame/Rockman4MinusInfinity'', the same thing happened with Wave Man and Crash Man, and the bubble MiniBoss in Cossack 3 is implied to be from a projector. [[spoiler: The alien also returns, but Mega Man [[BaitAndSwitchBoss kills it before it finishes forming.]] The TrueFinalBoss, the Petit Robot Masters, are also holograms.]]
** The Dr. Light capsules in the ''VideoGame/MegaManX'' series [[spoiler:(Or are they?)]].
* The VideoGame/DeusEx series has holograms for communication purposes, oddly the holograms look the best in the Prequel (VideoGame/DeusExHumanRevolution) even being mistaken for real people on occasions but the worst in the last (canonical) game (VideoGame/DeusExInvisibleWar)where they are tinged blue and strobe slightly.
* Unusually, two holograms appear in ''VideoGame/TheLegendOfZeldaTwilightPrincess''. Keep in mind that the ''Legend of Zelda'' series is mostly based on medieval Europe. [[spoiler: Both of the holograms are of Zant, a major villain in the game; the holograms act as the minibosses of the Palace of Twilight, the penultimate dungeon in the game.]]
* ''[[VideoGame/TearsToTiara2 Tears to Tiara 2]]'': Kleito is a dragon, but appears in the form of a [[Hologram]] of a little girl. The hologram is projected by [[{{Atlantis}} the floating city of]] [[GeniusLoci Tartetos]], which also supplies her with magic and allows her to teleport within city limits.
[[/folder]]

[[folder:Web Comics]]
* Galatea's [[http://bobadventures.comicgenesis.com/d/20090822.html hologram hat]] in ''TheInexplicableAdventuresOfBob.''
* In ''Webcomic/TimesLikeThis'', holograms are encountered frequently in visits to the future (or in objects brought back from the future):
** [[http://www.timeslikethis.com/index.php?id=570 A toy gun that fires a holographic bullet.]]
** [[http://www.timeslikethis.com/index.php?id=229 MichaelJackson-inspired shoes projecting holographic white tiles.]]
** [[http://www.timeslikethis.com/index.php?id=8 The "Holog-X" television.]]
** RobotBuddy [[http://www.timeslikethis.com/index.php?id=570 Nicki has the ability to project a flat video as a holographic image.]]

[[folder:Western Animation]]
* WesternAnimation/{{Arthur}} has ''Binky'', a virtual band, whose life performances are basically holographic projections.
* Synergy projects Holograms from Jerrica's Jemstar Earrings in ''WesternAnimation/{{Jem}}''.
* ScoobyDoo loved these. Villains often used projectors (holographic or otherwise) to make their act seem more genuine.
* IronManArmoredAdventures has holograms, coming in both a [[StarWarsANewHope blue]], full-body, full-size projection that's, and a small, flat, orange head-only projection that is emitted from a villain's communication wristband.
* On ''JimmyTwoShoes'', all Miseryville phones can project holograms.
* Like his comic counterpart, Nightcrawler in ''WesternAnimation/{{X-Men Evolution}}'' has a hologram device so he can appear normal. As the Evolution version of Nightcrawler is a bit more self-conscious, (not to mention for the first two seasons, the existence of mutants is hidden from the public) he uses it more often than the comic version.
* [[MissionControl Wade]] used a hologram projector to enable KimPossible to spend time with her cousin Larry while simultaneously accompanying Ron to Monty Fiske's mansion. [[spoiler:The real Kim was with Larry, somewhat to her dismay since she considered him an annoying gamer-geek. This left Ron and Rufus on their own when Fiske turned out to be a villain....]]
* ''MenInBlackTheSeries'': The two part finally ''The End Game Syndrome'' featured a hologram broadcast from orbit with the ability to project lethal energy beams.
