Working Principle of Acousto-optic Deflectors

An AOD operates by leveraging the acousto-optic effect, which occurs when sound waves propagate through a medium such as a crystal or glass. This propagation induces a periodic variation in the medium's refractive index, creating a dynamic grating. When a laser beam interacts with this grating, it diffracts, causing the beam to split in various directions. By controlling the frequency of the sound wave, the deflection angle of the diffracted light beam can be precisely manipulated.

The operation of an AOD can be summarized in four steps:
