The change of the zero Bragg order phase in the process of two-phonon acousto-optic diffraction with a change in the frequency of an acoustic wave has been theoretically and experimentally investigated. It is shown that changing the phase of the wave allows for a controlled rotation of the plane of polarization of linearly polarized radiation if diffraction occurs in an anisotropic gyrotropic crystal.
