The British-Hungarian physicist Dennis Gabor (1900-1979) the holographic photography received the Nobel Prize in Physics for his invention in 1971.
Dennis Gabor 5 born June 1900 in Budapest, Hungary, s Berthold and Gabor Ady (Jacobovits). The son of a businessman, he studied at the Technical University of Budapest (1918-1920) and Berlin (1920-1927). After his studies and completed his doctorate in engineering at the Technical University in Berlin, Germany, earned it the former latter 1927 in 1924,. He remained works as an engineer for Siemens and Halske research in Berlin at the graduation, until instead of Hitler in 1933 to making. At this time, he left Germany for the UK, where a job with the British Thomson-Houston company of rugby in England.
Gábor remained worked on improving power resolution electron microscopy with the British company 15 years from 1933 to 1948. The electron microscope could resolution increased a hundredfold on only the most beautiful microscopes light but were scientists so far "Atomic wireframe example see" (arrangement repeated atoms, step of atoms which are too small). The image is been distorted in two ways - tolerance (as if the focus was) and Sphericity (as if one were to a rain research). If an improvement in the former, this last Aggravée and vice versa.
A brilliant solution in Gabor occurred in 1947. What happens if one were to diffraction (tolerance) in a way that the information on the Atomic grid pattern made available. Is it, why not take a blurry photo of electrons, can clarify this image by optical means. This was the birth of holography. Gábor proposed a light beam, and share, send a bar to an object, one in a mirror. The two would first have the same wavelength and his (consistent) phase but the reflection of the object and the mirror to the photographic plate noise could be set up. Make the ocean waves rolling on a series of long, sand, one after the other. Make all equal in size, strength, and calendar. Now imagine you might range divide, in two, with two sets of waves that arrive at two different areas. Overlay these two at your choice, tilt and think, creates interference waves from each other. This interference would not completely chaotic but actually follows a pattern. This template "Diffraction", one can reconstruct the first waves. Now vary this first wave in size, strength and calendar (which introduced because of different weather, at sea). The pattern diffraction would accordingly differ, and even weather conditions could be reconstructed speculatively. This is Gábor wanted to electron beams. Beam the mirror would be unchanged, but the beam translated object should contain all irregularities imposed by this object. During their meeting in the photographic plate, two beams would in General inconsistent and intervention would occur model. This interference could then be recorded on film, and when light then laughs with the movie, it could take on the model of intervention and create a three-dimensional picture of reconstruction situation.
Gabor has worked beam conventional, filtered, step the basic technique from light sources. Mercury lamp and PIN Hole were used to form the first holograms inaccurate. But because this light was to diffuse holography is not economically 1960 with the development of the laser, the intensity of strengthened the light waves. However, Gabor showed mathematically as holography with electron - beam would operate as experience has shown that he has worked with ordinary light. The major problem of the practice which before 1960, however, not remained remaining none with the electron microscope wear of Gabor - was the double image also related by the holographic process. Gabor was the deficiencies from Elektronen--spherical aberration use objective to delete the second image.
Dennis Gabor
Gábor principle of holography and published results of his experiments in nature (1948), proceedings of the Royal Society (1949) and the actions of the physical society (1951). This work brought him in 1948 a position on the staff of the Imperial College of science and technology, London. In 1958 he was promoted to Professor of applied physics of electrons and it was this position until his retirement in 1967. His other work was research from Oscilloscopes high-speed, theory of communication, physical optics, and television, and it has received over 100 patents. Gabor was not pure scientific or isolated inventor; many popular works addressed the social consequences of technological progress and remained suspicious of the inevitable technological assumptions, nothing does, social could not also which caused problems to solve it.
Gabor has received many awards. In 1956 he was appointed to the Royal Society; he was named honorary member of the Hungarian Academy of scientists; and in 1971 he received for his holographic work of the Nobel Prize in physics. He died in London on 8 February 1979.
Read is happy little biographical to Gabor, information, even if some of the doctrine can be shared is science: current antiquity, edited by Allen g. de bus (1968) and the last dictionary of scientific biography. You can find (1971), in Les Prix Nobel (Stockholm, 1972) own - historical and scientific - statement of holography in his Nobel lecture. This French title contains still Conference in English and a holographic Photoplate to more object illuminate connected is. His popular work innovations: scientific, technological and social (1970), adult society (1972) and appropriate priorities of science and technology (1972) readable are. You are also repeated and it's a good idea, not only one of you may select the most recent.
