Acousto-optic effect and modulation

Educational content :

  • Bragg cell (Raman-Nath on request), study of diffracted beams as a function of the frequency of the acoustic wave
  • Determination of the diffraction angle, calculation of the lattice and the access time
  • Evaluation of the speed of sound wave in the material
  • Measuring the intensity of diffraction according to the power of the acoustic wave
  • Calculation of diffraction efficiency and absorption of the medium
  • Study of the acousto-optical modulation: application to the registration and transportation of an audio signal
  • Acousto-optic deflector : application to the projection and optical addressing
