The Origin of Holography
by Siena Jones BloggerHolography is one of the most important inventions ever made by science that aids in reconstructing 3 dimensional images with the help of holograms. Though the process was fabricated more than over 7 decades ago, it is still considered as the best means for creating true 3 dimensional displays. Rumour has it that during the course of this remarkable invention, there were many heroes of science who helped to give it shape. But in reality, there were actually three main pioneers - Dr. Dennis Gabor, Yuri N. Denisyuk and Dr. Emmett Leith.
Dr. Dennis Gabor was an engineer of Hungarian origin who first invented the holographic technique called wavefront reconstruction while working for an industrial laboratory belonging to an electrical engineering firm located in Rugby, England. However, his creation would have been futile without the contributions of Yuri Denisyuk and Dr. Emmett Leith, who represented the Vavilov institute in Leningrad, Soviet Union and a classified research lab at University of Michigan respectively. While reading a science fiction novel by Russian author Efremov, Denisyuk got inspired and created realistic, 3 dimensional photographs using modern optics. He got his work published in 1962 and called it photography of waves.
In the year 1952, Leith entered in the classified lab at University of Michigan for working on a covert military radar program. From 1955 to 1956, he reformulated the theory of synthetic aperture radar using physical optics. He realised that holograms can be improved greatly using the coherent light source of laser. Utilising a technique which he termed as ‘off-axis holography’ along with a laser, Dr. Leith eliminated the problem of double image that prevented Dr. Gabor from achieving high quality displays.
Thus the combined efforts of three brilliant minds gave us that which we so commonly know as holography in the modern times and use for a variety of purposes. Holographic rear projection film, electron imaging, data storing conventional optical discs, security features on credit cards and bank notes, and optical tweezers are just a few of the practical applications. In the near future, the technology is expected to become so advanced that it can be possible for tablets to project 3 dimensional images. Though we may be limited by what is available at hand now, scientists claim that the day is not far when we would be able to watch perfect holograms within theatres all over the world and even view crystal clear projections from mobile devices.
