Yuri Nikolayevich Denisyuk (Russian: Юрий Николаевич Денисюк; July 27, 1927 in Sochi — May 14, 2006 in Saint Petersburg) was a Russian physicist and one of the founders of optical holography in the former Soviet Union. He is known for his great contribution to holography, in particular for the so-called "Denisyuk hologram". He was a full member of the Russian Academy of Sciences (1992; corresponding member since 1970), doctor of physical and mathematical sciences (1971, candidate of sciences since 1964), professor (1980).
Yuri Denisyuk spent his youth in Leningrad and was in the city during the Siege of Leningrad. His scientific work started in 1954 (after his graduation from Saint Petersburg National Research University of Information Technologies, Mechanics and Optics) at Vavilov State Optical Institute. At that time he was inspired by the science fiction novel Stellar Ships by the Soviet writer and paleontologist Ivan Yefremov (where it was written about a three-dimensional image of alien head emerged in the ancient disc made of unknown material), and remarkable experiments by 1908 Nobel Prize laureate Gabriel Lippmann. In 1958, in other words before the times when lasers with their coherent light were invented, he started conducting his own experiments, where he used lamp emission on mercury vapor and was first to demonstrate 3D hologram. Starting from 1971 Y.N. Denisyuk was the head of the Laboratory of holography at Vavilov State Optical Institute, later he was the head of the whole department, engaged in holographic researches. Since 1988 he has also been the head of the Laboratory of holography at Ioffe Physical-Technical Institute of the Russian Academy of Sciences. He published about 240 research papers, which includes 35 inventions.
Yuri Denisyuk’s scientific work dealt primarily with physical optics, most notably holography. In 1962 Denisyuk invented the method of image recording in three-dimensional environments allowing one to save information about phase, amplitude, and the spectral structure of the wave coming from an object. These holograms can be produced using a typical beam of white light. This was determined by the government to be a scientific discovery, and was registered with the USSR State Committee on Inventions and Discoveries under No.88 as of February 1, 1962 along with the following statement: “The established is an unknown before phenomenon of spatial distortion-free colored image object occurrence under illumination from the three-dimensional element of the transparent material medium, in which the density distribution of matter matches the intensity extension of standing-wave field, which are formed around the object at radiated emission scattering on it”[This quote needs a citation]
Denisyuk received the Lenin Prize in 1970, upon receipt of the prize he was selected as a member of the Academy of Sciences of the Soviet Union, and appointed as a head of the newly established Laboratory of holography at Vavilov State Optical Institute. He proceeded to study the principles of dynamic holography for which he was awarded the 1982 USSR State Prize. He also participated in the establishment of a system for processing radar impulses using holography for which he was awarded the 1989 USSR State Prize. Denisyuk showed that progressive waves possess reflective properties, solving a problem with holograms formed in experiments with colliding beams. A great deal of his scientific work was dedicated to examination of quasi-deep holograms (the specific one-dimensional structure) and selectograms (a new type of periodic three-dimensional environment). Under Denisyuk’s supervision a range of new light-sensitive materials including reoksan, capillary porous glass, and various composite materials were developed for use as holographic recording media.
