Annotation
Light diffraction on ultrasound in the para-tellurite crystal is investigated. For acoustic waves in the frequency range 8.8$\div$80.0 MHz, the Bragg angles of incidence of the optioal beam at the ultrasound is measured. In the frequency range 30.0$\div$50.5 MHz, scanning of the light beam in the first diffractional order is performed, with a diffraction efficiency of 40$\div$80% at a controlling electric power of 120 mW. The features of the scanning are investigated by means of double light scattering on ultrasound. The reflector resolution measured for para tellurite $N=330\pm20$ differs from the calculated value N = 400 by 10-20%. The influence of thermal perturbations on the acoustooptical cell is qualitatively estimated.
