What is an Acousto-Optic Device?
An Acousto-Optic (AO) Device manipulates light using sound waves. It operates on the acousto-optic effect, where an acoustic wave passing through an optical medium creates a periodic variation in the medium’s refractive index, enabling diffraction, modulation, and deflection of light. These devices are widely used in lasers, imaging, and optical communication systems.
