Summary 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
Notes 4: Development and experimental investigations of individual sections and elements of acousto-optical system for the formation of TV images
