Hologram / Legends A hologram was a moving three - dimensional projection of a person or object , normally used in communication or entertainment . Operation . Holograms were used mostly in telecommunications as an alternative to screens . A holocamera of any recorder or receiver would acquire the dimensions , form and movements of an object by means of ray scanning . This vision then could be transmitted simultaneously somewhere else , or stored and reproduced on a holoprojector at a later time . Projected holographic images were visible from all sides , although matterless . Holograms were initially monochrome with a cyan hue , though following the Clone Wars , an additional layer of color was added to some holograms . In full duplex telecommunications , users could see each other ' s holograms , as if they were in the same room talking to each other , although not always in relative proportion . Standard holograms had a lesser quality than screens , since they were mainly monochrome and often flickered . The luxury versions could produce incredibly life - like full - color images , and were mainly used for entertainment purposes , such as at the Holographic Zoo of Extinct Animals , or Hologram Fun World , though they could also be used for disguises and other deceptions . Uses . Portable holovids could display a miniature hologram . Projectors were also implemented in many starship communication systems , both for use by pilots and passengers . Some droids could also record and display holograms ( eg . R2 - D2 ) . Members of the Jedi Council could attend Council meetings via hologram if absent from Coruscant or otherwise unable to be there physically . Their image would project on their formal seat and they would participate as if they were present . Holograms were also frequently used in scientific projects as schematics . Likewise , they could be used in military operations and briefings . During the Battle of Naboo , R2 - D2 projected a hologram of the Theed Royal Palace before organizing the assault . Prior to the Battle of Endor , a hologram of Death Star II illustrated the attack plan to the Rebellion pilots . Holograms were also used in targeting practice . For instance , the Republic clone army used holograms of B1 battle droids and B2 super battle droids , as well as holograms of Anakin Skywalker and Obi - Wan Kenobi , to train their clone sharpshooters and improve their ability to distinguish between hostile and friendly targets . Someone who forged holograms and passed them off as the real thing was known as a holo faker . Sentient programs would often use holograms as a method of interacting with living creatures . Sometimes , as in the case of Holiday , the program would use holograms as their primary method of communication . Storage of holograms . Holograms could be transmitted directly , or they could be stored in various storage devices ( such as holodisc s ) and in astromech units or other types of droids . The storage device would be hooked up with a holoprojector in order for the stored image to be accessed . Many droids had built - in holoprojectors . Hologram storage devices could be encrypted in case their contents were deemed sensitive or classified . Morgan Katarn recorded and encrypted a hologram for his son revealing his Jedi heritage . The hologram was stored on a holodisc and could only be accessed by the Katarn family droid WeeGee . However , Jan Ors and Xiong Wong ( with the help of Wires ) managed to partially crack the hologram and display it , albeit in a very bad quality , to Mon Mothma , Leia Organa and Luke Skywalker .
