Results were relatively unsatisfactory until the advent of the laser in 1960. Between 19, he worked in collaboration with the AEI Research Laboratory on holography. In 1949, Gabor joined the Imperial College of Science and Technology in London, first as a reader in electronics, and later as a professor of applied electron physics. Progress in the field was made very slowly until more efficient light sources became available, namely, the laser. At the time of Gabor’s research, holography was called "wavefront reconstruction." He developed the early principles of holographic theory while working on improvements to the resolution of the electron microscope. Today, holograms have a variety of uses, including being used to take measurements in particle physics for security in credit cards and currency notes in bar-code readers to take impressions of valuable artifacts and simply to capture three-dimensional images of animals, plants, or objects. He stayed there until 1948, and it was at BTH that he began the most important work of his career, founding the field of holography.Ī hologram is formed when the interference patterns of two waves of light are recorded on a piece of film. Soon, he began working with the BTH Research Laboratory. in Rugby, where he worked on gas-discharge tubes. He was employed by the Thomson-Houston Co. In 1933, as Adolf Hitler was coming to power in Germany, Gabor left the country, returning briefly to Hungary before settling in England. The seal is still used in street lamps to this day. 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. In 1927, Gabor accepted a position with Siemens & Halske AG. 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." He also created the first iron-protected magnetic electron lens. ![]() He visited often to learn more about physics in the presence of greats like Albert Einstein and Max Planck. There, he also had access to the University of Berlin. He attended the Technische Hochschule in Berlin where he received a bachelor’s degree in 1924 and a doctoral degree in 1927 in electrical engineering. 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. At age ten, he designed a type of airplane-like carousel, and his parents helped him attain a patent for it. As a youngster, he was interested in the inner workings of the things around him.
