Acousto-optic deflector

An acousto-optic deflector (AOD) is an optical device that uses sound waves to control the direction of light beams. It operates based on the principle of acousto-optics, which involves the interaction between light (photons) and sound waves (phonons). ### Key Components and Function: 1. **Interaction of Light and Sound**: - An AOD typically consists of a crystal material through which both light and sound waves can propagate.
