What are holography applications?
holography is a method of visually reproduction of objects as three -dimensional images. Unlike traditional photography, the object captured in the holographic image can change perspective based on the location of the viewer. There are several applications of holography, including art, storing information and security. The holographic process was developed by physicist Dennis Gabor in 1947. Only in 1962, however, three -dimensional visible holograms became practical. This depended on expensive equipment and expertise in the first years of its development. The prevalence of cheap lasers and other supplies at the beginning of 2000 has since been made available to holography to the budget fans.
One of the most common applications of holography is art. Three -dimensional holograms allow artists to capture interesting objects and scenes that can be displayed from many angles. The famous Surrealist Salvador Dali was one of the first to employ it as art in 1972. Many museums and other places around the world can explore a wide range of holographiof art works of art.
Information storage is another holography application. Holograms are able to hold a huge amount of data that is not necessarily in the visible image format. The only picture may contain information about the diversity, which can be accessed by reflecting light from different angles. Traditional optical storage methods, such as compact discs, can only be approached from one angle. Several companies examine the use of holograms as a device for storing high capacity for entertainment and computer technology.
This type of image reproduction can also be used in security applications. Complex holograms are much more difficult to reproduce compared to static images. For this reason, holograms are often placed on valuable objects to reduce the chances of counterfeiting. The common holographie security applications include credit card labels and images built -into a government currency. Important documents such as passports and identification cards are also often used to discourage illegal reproduction.
New holography applications are under way. Many scientists believe that holograms can be used to create realistic moving projections of people and objects. In the future, data that previously required 100 DVDs may be contained in one flat hologram. The development of optical calculations can lead to even greater use and dramatically increase the speed of computer processing and storage capacity.
