Holograms Replicable?

You see holograms everywhere… Drivers licence, deed, open a new mobile box and its hologram sealed, so is the drinking water that I buy… But what makes them non-replicable? is it just too difficult? or do we really even bother.

I went off searching for this and this is what I found

One interesting fact I found on How Stuff  Works is

If you tear a hologram in half, you can still see the whole image in each piece. The same is true with smaller and smaller

Now that gives me dope for another question (which I would probably figure out some other time) as to how is this possible? what kind of a technology makes it possible. Interesting it would be, to figure it out.

From what I understand, there are many types of holograms, there are many processes to make holograms.

Could not find much of information on Hologram Security. So visited a site of Hologram Manufacturer to find this.

holograms are virtually impossible to duplicate and to produce by average criminals. Therefore, they have become the integral part of many government and commercial security programs. They have been applied to documents, currency, ID cards and product labels. To further detert the counter-feiters, the holograms manufacturers, have added sequential, hidden text and other covert features to their security holograms. That’s why it is said that ” Security hologram is a unique optical security device that has combined the Physics and Optics to create a three dimensional image on a two dimensional surface that is used to protect the genuineness of the brand name and authenticity of a product against the spurious/ imitations/duplicates. “

So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly). Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
