Abstract

Optical holograms are difficult to counterfeit and are able to reconstruct a complete wavefront, ie a three dimensional image, this makes them very attractive for use, for example, in credit cards, on drugs, or in any advertisement. Today thet are increasingly easy to find, but few people have an idea of what is a hologram and why they are increasingly used. So will be introduce shortly some concepts of holography and its importance.
