What was invented by dennis gabor

Dennis Gabor was born in Budapest, Hungary on June 5, As a youngster, he was interested in the inner workings of the things around him. At age ten, he designed a type of airplane-like carousel, and his parents helped him attain a patent for it. By the time he was a teenager, he had a small laboratory in his house where he worked on his own experiments in photography, radiation, and wireless x-rays and developed a passion for physics.

There, he also had access to the University of Berlin. He visited often to learn more about physics in the presence of greats like Albert Einstein and Max Planck. During the course of his doctoral work, he developed a high-speed cathode ray oscillograph, which was detailed in his thesis "Recording of Transients in Electric Circuits with the Cathode Ray Oscillograph. There he was responsible for a number of discoveries, including a high-pressure quartz mercury lamp with a molybdenum a heat-resistant metal tape seal, which was subsequently used in street lamps.

Yet, when I reached university age, I opted for engineering instead of physics. Physics was not yet a profession in Hungary, with a total of half-a-dozen university chairs — and who could have been presumptuous enough to aspire to one of these?

Though electrical engineering remained my profession, my work was almost always in applied physics. My doctorate work was the development of one of the first high speed cathode ray oscillographs and in the course of this I made the first iron-shrouded magnetic electron lens.

This was also my first exercise in serendipity, the art of looking for something and finding something else , because I was not after a mercury lamp but after a cadmium lamp, and that was not a success. In , when Hitler came to power, I left Germany and after a short period in Hungary went to England. At that time, in , England was still in the depths of the depression, and jobs for foreigners were very difficult.

I obtained employment with the British Thomson-Houston Co. The invention was a gas discharge tube with a positive characteristic, which could be operated on the mains. Unfortunately, most of its light emission was in the short ultraviolet, so that it failed to give good efficiency with the available fluorescent powders, but at least it gave me a foothold in the BTH Research Laboratory, where I remained until the end of The years after the war were the most fruitful.

The first, the inability to obtain optimum results when the method was applied to the electron microscope, and the second, because the reconstruction step of the hologram was imperfect.

When the hologram was reconstructed, a virtual image appeared in the position of the original object but, unfortunately, the view of the image was marred by the presence of a spurious real image in line with it.

In , after investigating various optical set-ups to minimize the effect of the conjugate image, Gabor abandoned his research about holography. Gordon Rogers , perhaps the most enthusiastic researcher in holography, wrote in «As far I am concerned, I am quite happy to let Diffraction Microscopy die a natural death.

I see relatively little future for it, and am looking forward to doing something else. A holographic explosion was originated in the United States in the s after the invention of the laser in and thanks to the contributions made by Emmett Leith —who made the first hologram of a three dimensional object in — and other researchers from the Willow Run Laboratories, Ann Arbor, at the University of Michigan. This holographic explosion rehabilitated the figure of Gabor, who went from being virtually unknown in , to win the Nobel Prize in Physics in «for his invention and development of the holographic method.

The laser, one of the most important and versatile scientific instruments of all time, and the off-axis holography technique developed by Leith and Upatnieks in Willow Run not only opened the world of holography to the real world of three-dimensional objects, but also they resulted in a great number of scientific and technological applications in different areas.

In his Nobel Lecture, Holography, , Gabor stated: « Holography is based on the wave nature of light , and this was demonstrated convincingly for the first time in by Thomas Young , by a wonderfully simple experiment. Gabor finished his Nobel Lecture recognizing that the contributions of other researchers helped him to win the Nobel Prize : «Summing up, I am one of the few lucky physicists who could see an idea of theirs grow into a sizeable chapter of physics.

I am deeply aware that this has been achieved by an army of young, talented and enthusiastic researchers, of whom I could mention only a few by name. I want to express my heartfelt thanks to them, for having helped me by their work to this greatest of scientific honours.
