1st Edition
Acousto-Optical Laser Systems for the Formation of Television Images
The book addresses various approaches to television projection imaging on large screens using lasers. Results of theoretical and experimental studies of an acousto-optic projection system operating on the principle of projecting an image of an entire amplitude-modulated television line in a single laser pulse are presented. Characteristic features of image formation and requirements for individual components are discussed. Particular attention is paid to nonlinear distortions of the image signal, which show up most severely at low modulation signal frequencies. The feasibility of improving the process efficiency and image quality using acousto-optic modulators and pulsed lasers is studied.

Biography
In 1970 Mishik Kazaryan graduated from the faculty of general and applied physics of Moscow Phycotechnical Institute in specialty "Optics and Spectroscopy." Since 1970 he has worked in P.N. Lebedev Physical Institute, currently at the Department of Luminescence as the leading researcher. In 1975 he defended his PhD-thesis and in 1989 Dr. Hab. thesis. Mishik Kazaryan was conferred the professor title. Currently, the main research fields of Prof. Kazaryan are related to the creation of powerful tunable lasers, the study of the basic physical mechanisms responsible for the implementation of the Kazaryan plasma 3D-effect, the construction of acousto-optical color television systems and devices, laser medicine, the study of the mechanisms of laser acceleration of microparticles, studies of light-induced phenomena at multiple dynamic light scattering, and electrically induced drift aquacomplexes in aqueous solutions, the development of new approaches to the problem of laser isotope separation, the development of new solutions to the problem of alternative and hydrogen energy, the development of new composite materials with a long luminescence, the synthesis of new nanomaterials. Prof. Kazaryan is one of the leading scientists working in the field of physics of gas lasers and active optical systems. He published a number of reports in leading scientific journals and encyclopedias, international patents, 11 books and 9 collections of selected articles in various international journals. He published more than 500 scientific papers. M.A.Kazaryan established a new method of exciting metal vapor lasers. He developed highly efficient lasers which are currently commercially available in Russia. For his work on the physics of lasers and optical systems, MA Kazarian together with team members were awarded the State Prize of the USSR in the field of science and technology for 1980. M.A.Kazarian together with A.M.Prokhorov, Yu.V. Gulyaev and Yu.A.Trutnev have developed many aspects of modern laser physics and its applications. In 2003 he was elected a full member of the A.M.Prokhorov Academy of Engineering Sciences and in 2008 a Foreign Member of the National Academy of Sciences of the Republic of Armenia. Mishik Kazaryan is a supervisor of many international projects of ISTC and CRDF. Currently, he is the scientific secretary of the Scientific Council on Luminescence, a member of program and organizing committees, chairman of the sections at many national and international conferences.Misik Kazaryan lectures on physics of lasers and their applications in many research centers and universities in Russia and many other countries. Under the leadership of Prof. Kazaryan a number of specialists, working in Russia and in the CIS countries and abroad, was prepared. Prof. Kazaryan is a member of the editorial board of international scientific journals «Lasers in Engineering», «Alternative Energy and Ecology", a member of the Council of the Euro-Asian Physical Society, a member of the "National Foundation of Science and Advanced Technologies" in Armenia. M.A.Kazaryan was awarded the A.I.Berg Medal (2013) and the N.N.Semenov Medal.
