Since our childhood, we are familiar with holograms mostly through science fictions and TV shows like “Star Wars” and “Star Trek”. Hollywood makes this type of technology look easy but in the real world, it is different and a bit complicated. Let’s have a look at this Technology.
What is Hologram?
A hologram is a physical structure which diffracts light into an image thus producing the holographic image that can be seen by looking into illuminated holographic print or by projecting image on a screen. It’s a 3D image formed by photographic projection. This whole process is named as Holography.
How does it work?
Holography is based on the principle of interference. A Hologram captures the interference pattern among two or more beams of Laser lights. One beam is shone directly on the recording medium and acts as a reference to the light speckled from the enlightened scene.
Surprise Uses of Holography in Today’s Worlds:
Recently Holography is being used in many things around us, to benefit us in more proper ways. Some of these uses are described below.
- Military Mapping in America:
A company in America has delivered over 13000 3D holographic maps of the “Battlefield” for the US Army. This will help military men to better understand the field and will help them in training with a three-dimensional look.
- High Information Storage Capacity:
Holography can be used for storing huge amount of data with its realistic details. They can store an unthinkable amount of data and the important thing is this data can be restored from any piece of the hologram. As the data is stored in three dimensions so it is overlapped and is more reliable and secure.
- Medical uses of Holography:
In the medical field, many systems generate complex data with help of advanced technology like MRI or Ultrasound, but they produce 2D images. Holographic technology can help them to make 3D images of their results. A company in Scotland has successfully made this type of data images for training and display. To date, the company has produced 3D holographic images of structures including the brain, liver, lungs, heart, skeleton, vascular system, nerves, and muscles.
- Fraud and Security:
Holograms are complex objects which are difficult to make that’s why they are much important for security purpose at the commercial level. Credit cards, Debit cards and Banknotes etc these entire have a security Hologram to save them from cheat and fraud.
- Holography as an Art:
The role of artists in holography is very old. In the UK, Margaret Benyon, the “mother” of British creative holography, managed to secure access to complex and expensive holographic recording equipment as early as 1968. She was on an art fellowship in the Mechanical Engineering Department at Nottingham University. Eventually, she submitted a Thesis naming,” “Art of Holography”. Most recently a show on creative Holography took place in London in which many artists around the world have participated to show their holographic artworks. During 2018, an academic convention in Portugal for artists and scientists, wanting to discuss the progress of holographic art and technology will take place.

Future of Holographic Technology:
In July, a team at Tokyo University was the first to create a touchable holographic image. A new device has been created to transmit 3Dimensional images in close to real time. This is also named as Tele-presence holographic technology. This system as designed by Teleportec will be having two running system: one at the live image which is being holograph and the other at the special podium to display image to other time-space.
Another small group of researchers from the University of Arizona has disclosed the fastest 3D motion hologram. They have successfully demonstrated a display screen which presents image viewable from all sides without 3D glasses.
So the future of Holographic Technology is brighter and there are more new things to come in coming days.
