subject: The Science Of Holograms [print this page] The term hologram originated from Greek word holos (whole) and gramma (message). The definition of hologram is that it is a laser generated image with three dimensional properties from a photosensitive medium. The entire method is called holography. The concept of holography first came into existence in 1947.
In order to produce a hologram a beam of monochromatic light is split into two parts; one part of the beam is put on the object and then reflected onto a high-resolution photographic plate. The other part of the beam is used as a reference beam and it is directly put on the photographic plate. The interference pattern of both the beams is then recorded on the plate. The developed pattern is then illuminated in the same direction of the reference beam by a coherent light, the developed pattern then creates a three dimensional image. The view keeps changing when viewed from different angles. When the concept is converted into a form of a sticker it is called a hologram sticker.
Hologram stickers enhance the beauty of the product and also add many security features to it. First impression is the last impression, a hologram sticker adds a punch to the packaging of the product and it enables the packet of the product to leave a strong first impression. On the security front they help in establishing the originality of the brand. Hologram stickers cannot be duplicated. With advancement in science and technology the benefits and usage of hologram stickers have also been increasing. If the hologram sticker is tampered it indicates that it has already been used.
Since we have understood the benefits of holograms, it is now important to ascertain their feasibility. Hologram sticker definitely does not come cheap, there is a cost attached to it, but it is a form of an investment that helps the brand in the long run. Moreover it is also important to understand that when the look of the product would get enhanced the sales would also increase. Last but not the least the leading hologram sticker manufacturers are constantly doing lot of research in order to offer feasible hologram solutions.
