Exploring the Possibility of Holograms: A Fascinating Concept

In summary, the conversation discusses the possibility of holographic projections without an apparent surface for projection. The website www.io2technology.com claims to have such technology, but there is confusion about how it actually works and concerns about its safety. Despite some interest and hype, the technology is still in the prototype stage.

Is it possible?

I have always wondered; and have never heard anyone mention the possibility.

By hologram i mean to say a projection of an image without an apparent surface for projection. Perhaps in a container of some sort. I am so unknowledgeable in the subject i find it hard to think of correct terminology.

This is so Cool

This is so cool! Anyone has any idea of how it works? It claims that it does not add anything to the air. Would it just simply be ionised air?

I've been trying to wrap my head around this for over a year. I was thinking ionized air but would that really allow images to be projected on it? Hmmm.

There was quite a bit of hype when the company first announced this device. The hype seems to have died down a lot since then. I'm surprised they haven't licenced the technology yet. This would be great for advertising.

Isnt it Crumbles!? Am i not the only one amazed by this.

Take a look at some of the screenshots.

They used to have videos on the site. I'm not sure if they still do. I know they took down a lot of the videos but I still have them saved on my hard drive. If anyone wants them, PM me and I'll email it to you. You just need an email account that let's you receive attachments ~5MB in size.

I was thinking maybe the gadget produced a curtain of ionised air and then there's some kind of electron gun that beams electrons of various energies at it and that somehow interacts with the ions to emit light of various colours depending on the frequency of the electrons from the gun.

But I don't think it can be that simple because air is mainly Nitrogen and Oxygen and it would be hard to produce many colours from just those two elements. Also, having electrons fired all around would not be safe.

The site claims they use LASERs but I can't see how! But boy do I wish I had got on to such an invention at 20 yrs of age!

I don't understand why this isn't extremely popular. Something so futuristic should be the a large interest for companies.

There is a lot of interest, the company was plugged by cnn last year. The system is still very much a prototype.

IIRC it worked like a stereoscope. There are slots in the screen so that each eye effectively sees a different picture.
Big drawback is that the user has to hold their head in a specific location.
No moving around allowed.
 

FAQ: Exploring the Possibility of Holograms: A Fascinating Concept

What are holograms and how do they work?

Holograms are three-dimensional images created by the interference of light waves. They are made by splitting a laser beam into two separate beams, one of which is reflected off of an object and the other is reflected off of a mirror. When the two beams are combined, they create an interference pattern which is captured on a photosensitive material to create the hologram.

Can holograms be seen without any special equipment?

Yes, some holograms can be seen without any special equipment. These are called reflection holograms and can be viewed with just the naked eye. However, other types of holograms, such as transmission holograms, require a light source to be seen.

What are the potential applications of holograms?

Holograms have a wide range of potential applications, including in entertainment, medicine, education, and security. They can be used for immersive virtual reality experiences, medical imaging, holographic displays, and authentication of products and documents.

Are holograms a new technology?

No, the concept of holography was first introduced in 1947 by physicist Dennis Gabor. However, it wasn't until the development of the laser in the 1960s that holograms became a practical technology. Since then, holography has continued to advance and find new applications.

What are the challenges in creating realistic holograms?

One of the main challenges in creating realistic holograms is the need for a large amount of data to accurately capture and reproduce the object being imaged. This requires advanced technology and computing power. Another challenge is creating a wide viewing angle for the hologram, as most holograms can only be viewed from a specific angle.
