Aplication of Acoustooptics in Electronic Devices

The problems associated with the application of acousto-optic devices in information display systems and signal processing are discussed. Principles of working of acousto-optical cell as basic element of any acousto-optical system is considered. Specific features of the operation of devices in various modes with the use of an acousto-optic cell: a modulator and a tunable filter are described. The issues of the topology of planar and volumetric acousto-optical devices on niobate lithium and silicon substrates are reviewed. The prospects and possibilities of using surface acoustic waves for controlling radiation are indicated. Structural diagrams and technical characteristics of acousto-optical devices for various purposes of optical information processing as in volumetric as in planar form with using surface acoustic waves: optic tunable filters, acousto-optic scanners, laser light modulators, broadband delay line, receiver-cymometer, etc. are provided.
