The acousto-optical deflector enables a wide range of deflection angles of incoming laser beams to first order. The deflection angle changes proportionally with the applied frequency. The requirements for a deflector are typically characterised by the number of points that can be displayed, the tuning range (RF) and the resulting deflection angle, the minimum diffraction efficiency that can be achieved, the wavelength and the beam parameters.
