Abstract

Different kinds of acousto-optic imaging systems have been observed from the point of view of their capability to transmit and process information. The major attention have been paid to the system providing image projection. Acousto- optic light projection system represents a kind of light information systems in which two kinds of information are used: basic and auxiliary information. The auxiliary information contains data which are used in order to arrange the basic information in such form that it would require no additional decoding means. When such auxiliary data are used, the signal-to-noise ratio falls because each operation introduce its own noise. Several ways of additional information input have been considered from the point of view of the useful information transmission optimization. In order to perform this consideration, such standard information parameters as information capacity and information transmission capability have been assigned to the system as well as to its separate links. These parameters limitations providing by acousto-optic deflection and modulation units have been estimated. These limitations are connected with the certain contradiction between attempts to increase both information parameters simultaneously. This contradiction is connected with nature of acousto-optic interaction, however it differs from that taking place while optimizing the information parameters of acousto-optic spectrum analyzers. The results of information parameters estimation for the systems we had experimentally performed, have been stated and discussed.
