Acousto-optic deflectors (AODF) are based on the deflection of light when it travels through an optical isotropic medium with propagating acoustic wave due to periodic variations in the refractive index produced by the ultrasound wave. AODF address precise angular control of an optical beam by frequency tuning of RF driver .Acousto-optic deflectors (AODF) are based on the deflection of light when it travels through an optical isotropic medium with propagating acoustic wave due to periodic variations in the refractive index produced by the ultrasound wave.
