Yuri Denisyuk 1927 - 2006

Yuri Nikolaevich Denisyuk (Russian: Юрий Николаевич Денисюк; July 27, 1927, SochiMay 14, 2006, Saint Petersburg) was a Soviet physicist known for his contribution to holography, in particular for the so-called "Denisyuk hologram".


After the discovery of white-light holography by Professor Yuri Denisyuk (St.Petersburg, Russia) in the 1960s and the coming of lasers, museum objects and artifacts became the first subjects of holographic recording. Famous museums throughout the world provided artifacts to record as holograms, which reconstruct three-dimensional images of objects with high resolution and maximum accuracy. The principle of Denisyuk holography is rather simple to understand.

The object is exposed by laser light that passes through transparent holographic plate.


The developed plate is illuminated by a white spot light. A viewer sees the object as an holographic image behind the plate.

Working at the State Optical S.I. Vavilov Institute in Leningrad (now St.Petersburg), Prof. Denisyuk developed a technique to use He/Ne and Kr lasers (red band of spectra) and his own high definition photomaterials, sensitized to red light, to create a gallery of high quality holograms of objects from the Hermitage, including large sizes (up to 80 x 120 cm).
