The word, hologram is composed of the Greek terms, "holos" for "whole view"; and gram, meaning "written". A hologram is a three-dimensional record of the positive interference of laser light waves. A technical term for holography is wavefront reconstruction. In holography, we record the positive interference of matching wavefronts of laser light. This three-dimensional record is formed as a diffraction pattern; a series of very fine lines, or concentric circles. This diffraction grating bends the viewing light back onto the path of the original recording wavefronts of laser light. The three-dimensional version of the object - the hologram - is reconstructed as light.
Worldwide, counterfeiters rob almost US$ 300 Billion of legitimate business turnover! This is a seriously threatening issue - while the counterfeit product absorbs your goodwill, it passes on its own shortcomings to your products. The results can be disastrous. Several deaths (of people and brands) have been reported due to a counterfeit product.

The very concept of Holograms has emerged from the need to have a mark of authentication that is simple enough to be identified by even an untrained or illiterate eye, and yet sophisticated enough to make it near impossible to be duplicated or replicated. A Hologram is the culmination of several process involving physical, chemical and artistic inputs. The extremely high level of technology that goes into its manufacture coupled with the exclusivity of the technology makes it far beyond the reach of a counterfeiter.

Uniqueness of a Hologram
Uniqueness is inherent in the very process of Holographic Recording. If the same holographer but at two different point of time or if two different holographers but at the same point of time, were to carry out holographic recording from " the positive" of each layer, minute examination will reveal subtle differences between the two versions of the same hologram created by them. Thus it is impossible to make an exact replica of the hologram and therefore it is regarded as virtually impossible to replicate.
A Hologram is the "Interference Pattern" on the photosensitive coating on the surface of the glass plate created by the interaction of two beams of coherent light from a laser. Each time a holographic recording is undertaken, there will be subtle variations in the above referred "Interference Pattern", making such pattern unique . Thus, uniqueness is inherent in the very process of holographic recording. It is not possible to make an exact same replica of a hologram and hence it is regarded as virtually impossible to replicate .

Hologram technology, the first step is to take advantage of the interference principle record objects lightwave information , namely shooting process: holographic technology. Subject diffusing the object beam is formed under laser irradiation ; another part of the laser as a reference beam incident on the hologram , and the object beam superimposed produce interference , each point on the object lightwave phase and amplitude converted into changes in space strength, and thus the use of the interference fringes between the contrast and spacing objects lightwave information recorded . Record the backsheet through the interference fringes the processing procedures of the developing, fixing , etc. , will become a hologram or a hologram ; The second step is to use diffraction theory reproducing lightwave information of the object , which is the imaging process : the hologram is like a complex grating, the coherent laser irradiation , a linear recording of the sine -type hologram diffraction waves can generally be given the two images , i.e. the original image ( also known as the initial image) , and the conjugate image . The reproduced image three-dimensional real visual effects . Each part of the hologram recorded in the optical information of each point on the object , and hence in principle each of its portion can reproduce the entire image of the original , a plurality of different image by the multiple exposure can also be recorded on the same one backsheet , and can not interfere with each other to show.
Hologram technology types:: Holographic projection technology is divided into a total of three ways:
1. Air projection and interactive technology: This is Massachusetts, a 29-year-old named Chad Dyne Polytechnic graduate invention, is a milestone in technical, it can be formed in the gas stream wall projected image with interactive features. The principle of this technology sources mirage, the image projected on the water vapor on uneven due to molecular vibration level and a strong sense of three-dimensional images form.
2. Laser beam technology: 3D image of a laser beam projected entity Japan Science and Technology Corporation invented this technology is the use of nitrogen and oxygen when dispersed in the air, mixed into the gas into a burning syrup-like substance, and in the air to form a a short 3D image. This method is mainly performed in the air is constantly small blasting.
3. 360 degree full line shows: it is by the Institute for Innovation and Technology of the University of Southern California researchers announced that they successfully developed, this technology is the image in order to achieve a three-dimensional image projected on a high-speed rotating mirror, just some dangerous . It can be said that these technologies in many countries in the development of this technology it contains no exaggeration to say, who is the first to use this technology, and whoever was first into the advanced technology of the future ranks. The holographic projection technology is the reverse of the holographic technology show is on the air or a special three-dimensional lens to form a three-dimensional image. Unlike flat-screen projection only by a three-dimensional perspective, shadows and other effects in the two-dimensional surface, holographic projection technology is truly rendered 3D images to different sides of the image can be viewed from any angle of 360 °.
