Diffraction of light by acoustic waves at high frequencies, i.e. Bragg diffraction, is discussed, and the possibility of investigating the acoustic and acousto -optical properties of crystals using this method is presented. The mea¬suring systems used, measurements of the propagation velocities and absorption coefficients of acoustic waves, and the photoelastic constants for crystals of melt quartz, Ti02, CaF2, Ge0", and LiNbO3 are presented.
