Abstract: The working frequency range and the maximum scanning angle of an acousto-optic deflector depend on the width of the acoustic beam, i.e., on the width of the transducer. The proposed construction of a Bragg-type deflector makes it possible to increase the scanning angle severalfold without altering the transducer geometry or its .construction. A quantitative calculation is made for the proposed deflector. Optimal acousto-optic materials for this deflector are suggested.
