What is hologram? What is the future of holograms?

 

1)What is HOLOGRAM

Holography is a photographic technology that  records the light scattered from an object, and then  presents it in a way that appears three-dimensional. Holograms pop up in movies such as "Star Wars" and "Iron Man," but the technology has not quite caught up to movie magic. But we believe it will apply in various sectors very soon.

 

2)How does a hologram work

A hologram captures the interference pattern between two or more beams of coherent light (i.e. laser light). One beam is shone directly on the recording medium and acts as a reference to the light scattered from the illuminated scene.

3)What is the future of holograms?

Holography has been used to make archival recordings of valuable and/or fragile museum artifacts.  Sony Electronics uses holographic technology in their digital cameras.

The kind of smartphone hologram technology that enables floating-in-the-air 3D holograms is in our far future. But in-the-screen holograms are coming soon, according to one company. The popular HD video camera maker RED is working on a $1,299 smartphone called the Hydrogen One that it says sports a holographic display.    

  Medical

Holography is on its way to revolutionizing medicine. It can be a tool for visualizing patient data in training students and surgeons.Current systems like Magnetic Resonance Imaging (MRI) and ultrasound scans generate complex data using advanced imaging technology. This technology has the capability to produce full color, computer-generated 3D holograms.

Using these 3D images for training and display, holograms require no viewing devices or glasses. Students and doctors can simply “look”, unhindered, at the three-dimensional images. These images can include the incredibly complex organs and systems of the body, like the brain, heart, liver, lungs, nerves, and muscles.

Fraud and Security

Because Holograms are complex and hard to make, this makes them an incredible advantage in commercial security.

If you have a credit card, you have a hologram. “That small silver rectangle of a dove on your credit card is a white-light, mirror-backed, transmission hologram. It displays a three-dimensional image which is visible as you move from side to side, and changes color as you tilt your card up and down.” These holograms are incredibly difficult to forge.

4)Benefits or advantages of 3D Hologram

➨It is very cost effective solution to make and to hire. ➨It has higher storage capacity compare to other methods. ➨It delivers enhanced feasibility of objects including depth. ➨They are complex patterns and hence offers security in wide applications as mentioned above.

   

Inventer of hologram:-Dennis Gabor

Holography/hologram

Holograms were invented by a brilliant Hungarian-born physicist named Dennis Gabor (1900–1979) while he was working in the UK. He'd been researching optical physics in the 1940s, and carried out his breakthrough work in holography in the early 1950s.
