What is holography?

Holography is a three dimensional technology which involves around the practice of creating holograms or 3D images of objects. Holograms are photographically recorded images of a holographic subject with the help of a light field which was captured when different light sources fell and reflected of the surface of the holographic subject. The recorded light field can be reconstructed later even in the absence of the original subject to create a 3-D reproduction of the subject as if the subject was present at that very moment. The reproduced 3-D image can produce visual depth cues like perspective and parallax. The depth cues keep shifting with changes in the relative position of an observer.

How is it revolutionizing the sphere of communication?

Holography is still in a nascent stage of development and will have to cover some ground before it becomes a mainstream technology. However, some wonderful experiments have been carried out and its usefulness has been established beyond reasonable doubt. Lack of suitable supporting technology is impeding its growth in some cases.

  1. Use in audio and video long-distance communication: Today when people make video or audio calls, they can only see a 2-D image on their display monitors or a voice is reconstructed on their audio receiver. However, it won’t go beyond the realm of reality if in the near future, two company bosses can create holographic images of each other’s work places in their rooms and nature of the communication will be almost life-like. A boss may stay in his home and make a presentation to his employees in office and make it seem as if he is physically present. A father can call his daughter (who is at home) from office on her phone and make her feel as if he is really there with her in the room.
  2. Holographic entertainment shows: It is becoming common in some parts of the world to create holograms of real or animated DJs and performers and making them play in packed arenas and discotheques. The experience is no less enjoyable than when a living person is performing. In fact, it could actually be better because chances of on stage goof-ups will reduce. It also means that artists won’t have to travel. They would be able to reach out to a much wider global audience. Beyonce for instance, will be able to perform in the comfort of her studio and entertain people in Europe, Asia, Africa and America at the same time just by installing special holographic screens at the venues!
  3. Use in movies and videogames: Use of holograms is making movies and videogames more realistic day by day. Richard Parker, in Life of Pi, was a holographic 3-D creation and no one could tell that it wasn’t real. That is the level of perfection that can be achieved.

Conclusion

The use of holographic technology is endless. Holographic communication would allow teachers from cities to tutor students in schools which are in remote villages. Medical practitioners and can ask for expert opinions by reproducing the exact conditions within a body and sending the life-like images across. Graphene, one of lightest and most bendable materials known to man can be used to make receptive screens where holographic images can be projected can be used to capture 3-D photos of organs inside a human body. There could also be applications in military communication and technology. The possibility is limitless!
