1. Yuri Nikolayevich Denisyuk was a Russian physicist and one of the founders of optical holography in the former Soviet Union.
Yuri Denisyuk is known for his great contribution to holography, in particular for the so-called "Denisyuk hologram".
Yuri Denisyuk was a full member of the Russian Academy of Sciences, doctor of physical and mathematical sciences, professor.
Yuri Denisyuk spent his youth in Leningrad and was in the city during the Siege of Leningrad.
Yuri Denisyuk published about 240 research papers, which includes 35 inventions.
In 1962 Yuri 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.
Yuri 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.
Yuri Denisyuk proceeded to study the principles of dynamic holography for which he was awarded the 1982 USSR State Prize.
Yuri Denisyuk participated in the establishment of a system for processing radar impulses using holography for which he was awarded the 1989 USSR State Prize.
Yuri Denisyuk showed that progressive waves possess reflective properties, solving a problem with holograms formed in experiments with colliding beams.
