He experienced the inventor’s dream of seeing an idea grow into concrete applications. 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. future of industrial civilization. 1962); Emmett N. Leith, “Dennis Gabor, Holography and the Nobel Prize,” in Proceedings of the IEEE, 60 (1972), 653–654, and “The Legacy of Dennis Gabor,” in Optical engineering, 19 (1980), 633–635; and Tom Mulvey, “Fifth Years of High Resolution Electron Microscopy,” in Physics bulletin, 34 (1983), 274–278.).
in 1927 with a thesis related to the development of one of the first high speed cathode ray oscillographs. . The invention of the laser coincided with a clear increase of interest in holography, and many of the achievements of this period could have been, and in some cases were, produced without the use of lasers.
The idea of a two-step imaging process came directly from Bragg’s X-ray micro scope, described in 1942, in which holes were drilled in a brass plate that corresponded to the photo graphically recorded image of an X-ray diffraction pattern produced by a crystal lattice. When the plate was illuminated with monochromatic light, an image of the crystal structure could be viewed through the microscope. As proof of his fruitful work as an inventor, Gabor filed 62 patents between 1928 and 1971. In 1933, a few weeks after Hitler came to power, Gabor left Germany because the company did not renew his contract due to his Jewish origin. Returning briefly to Hungary, he used the patents of a new lamp design to negotiate an inventor’s agreement to go to England and work on its improvement. Gabor came up with the answer to this question while he was waiting for a game of tennis on Easter Day 1947 and it was to consider a two-step process. as "an experiment in serendipity," coined the term hologram from the Imagine them all equal in size, intensity, and timing.
Dennis Gabor showing as an off-axis hologram of a transparency is recorded. Medal of Honor of the Institution of Electrical and Electronic Engineers,1970. Processes within holography share similarity to those within photography however there are major differing factors. In the former he confesses, “Any book on the future will tell more of its author than about things to come.” Gabor’s beliefs were essentially those of a conservative and benevolent humanist.

. 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. Meanwhile, attempts were under way to build a working electron microscope, based on Gabor’s holographic principle, in the new research labora tories of Associated Electrical Industries, at Al dermaston. With the revival of holography, he was much in demand as a speaker on the subject.
The regions of interference set up a standing wave which
During the following years, the wave-reconstruction technique was studied by Gordon Rogers in England, Adolf Lohmann in Germany and at Stanford University by Paul Kirkpatrick, Albert Baez (father of the singers Joan Baez and Mimi Fariña) and Hussein El-Sum.
Gabor was the only refugee to be employed by the B.T.H.
This was the genesis of holography. Doing classified radar research at the Willow Run Laboratory of the University of Michigan, Emmett N. Leith first became aware of Gabor’s work in late 1956, although not until 1960 did he and his collaborator, Juris Upatnieks, initiate a research program. Encyclopedia.com. The second stage of holography requires the hologram to act as a diffraction grating or medium that splits, or diffracts, light into multiple beams that travel in different directions while the image of the subject is then reconstructed in order to display the final holographic image; the diffraction process gives each beam the ability to reconstruct the entire object.

This is what Gabor wished to do with electron beams.
