Subject of study. In this paper, the features of the acousto-optic diffraction of terahertz radiation by an ultrasonic field with a periodic inhomogeneity are theoretically investigated. Aim of study. Revealing the optimal parameters for the implementation of an effective terahertz radiation deflector. Method. To improve the energy efficiency of the deflector, liquefied SF6 gas was chosen as the interaction medium, and to increase the number of resolvable light spots, it was proposed to use a sectioned phased ultrasound transducer. Main results. The features of the acoustic field generated by such a transducer are shown. Analytical relations are derived for the main parameters of the acousto-optic deflector. Practical significance. The possibility of a fivefold increase in the number of resolvable spots compared to an acousto-optic deflector using a single-section transducer of the same length is demonstrated.
