Hologram is an image registered with use of coherent laser light. It allows to preserve the 3-D information of a heliographed subject. With a single source of white light, the image is "played back" and appears in 3-D exactly as it was registered in the studio. Image can project deep inside, or "stick" out of the picture. Virtually impossible to copy and displaying unique visual effects, they present themselves as an unbeatable security solution for brand protection and brand promotion.
Every Industry and any industry can use the Holographic products to enhance the image of their brands in the market as an genuine and authenticated brands. They are used for attractive product packaging, security applications (they are almost impossible to counterfeit), fancy gifts, etc. Holograms are new media of 3-D art, registration of priceless artifacts, etc. They are also used in new technology aircraft, automobiles, etc. A few leading companies are also working on Holographic video and TV systems. For your quick reference, some of the industry segments where Holograms are used very frequently are as follows:
List is ever growing & expanding.
Yes, and no. It is possible to make a hologram of photograph, but photograph itself contains flat, 2-D image information. Therefore on the hologram it will also look flat. It would look just like a flat photograph floating in the space on front, or behind the frame. The third, missing dimension of a photograph cannot be reconstructed by holographic process.
This is an important basic step before going for the commercial production of Holograms. As with many creative art forms, there are many choices available depending upon what we want to accomplish. Some basic things that are used, are as follows:-
1) 2D Objects (Graphics, Illustrations, Photographs etc.).
2) 3D(Miniature Models, Actual objects, Sculptures).
3) Specially Shot Motion-pictures.
The different kinds of Hologram Master are as follows:-
1) 2D Hologram Master.
2) 2D/3D Hologram Master.
3) 3D Hologram Master.
4) Flip-Flop Hologram Master.
5) Dot-Matrix Hologram Master.
6) Stereo Hologram Master.
7) Photopolymer Hologram Master.
Modern holography dates from 1947, when Dennis Gabor, a scientist researching ways to improve the resolution of the electron microscope, develop what he called holography. This was an amazing discovery given that Gabor did not have at his disposal modern laser light sources considered key to modern holography. Some twenty-three years later, 1960, the modern laser was invented and serious work in holography began. In 1971 Dr. Dennis Gabor was awarded the Nobel Prize in Physics for his work in holography.
It was two University of Michigan researchers who, in 1962, theorized that holography could be used as a three dimensional visual presentation. These individuals, Emmett Leigh and Juris Upatnieks, happened upon Gabor's work and decided to apply his theory with the newly invented laser light sources. The result was the first laser transmission hologram of 3-D objects. These transmission holograms produced images with clarity and realistic depth. Unfortunately, these transmission holograms required laser light to view the holographic image.
The work of Leigh and Upatnieks brought about today's modern holography equipment. The use of lasers, mirrors, splitters and lenses used in laboratories around the world for creating holographic images can be credited to their work. Leigh and Upatnieks also learned the importance of stability in the holography lab. Unlike modern photographic film which can be exposed for a fraction of a second, many holographic images take seconds or even minutes to expose to a photographic plate. During the exposure, even the slightest movement can destroy the exposure and require starting over again.
Like so many scientific advancements, holography was simultaneously being developed by other scientists. It was a Russian, Uri Denisyuk, who, in 1962, brought the work of Gabriel Lipmann (1908 Nobel Laureate) to holography and produced the first holograms that could be viewed in regular incandescent light. Advancements in laser technology also served to broaden the possibilities of holography. The pulsed - ruby laser, developed by Dr. T. H. Maimam of the Hughes Aircraft Corporation in 1960, was such an advancement. The pulsed - ruby laser system emits a very powerful burst of light that lasts only a few billionths of a second. This allowed holographic plates to be exposed much more quickly. As a result one could now produce holograms of high-speed events, such as a bullet in flight, and of living subjects.
Perhaps the most important result of Stephen Benton's work was that it lead to the ability to mass produce holographic images using optical embossing techniques. Embossing allowed the images to be reproduced by a press that stamped the image into plastic surfaces. With costs very low as a result of the embossing techniques, the publishing, advertising, and banking industries, are now using embossed holograms.
The reasons for using holograms and holographic products are as following:
1. Impact :: Holograms are eye-catching and will be looked at significantly longer than other graphic mediums. If a customer name or logo or slogan is on the hologram, the message is enforced.
2. Pass Around Value :: people are impressed by the good holograms and are likely to bring them top attention of colleagues and associates.
3. Retention :: people tend to keep good holograms. even we received call from those persons that after 6 months or one year after they had been given our visiting cards wearing holograms. Do you think that a pen or Calendar or a diary can do this? We do not think so.
4. Security :: 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. "
5. Commercial Reasons :: Holographic products, commercially, constitute a very unique market in them selves. They are sold in the market as retail products. e.g. Greeting cards, Direct-mail literature, collectibles, trading cards, packaging and displays etc.
6. Promotional reasons :: holographic materials and its allied products catches the attention of the prospects. Actually, they diffract the seven colours of the spectrum when the light falls on them. The unique three dimensional images and colours inherent to the products never let anybody go without a look that is significantly longer then any other medium. Once applied to the product, the apparent value of the product is elevated no matter which way you look at it.
