Description
Acousto-optic effect refers to the phenomenon of diffraction of light through a medium which is disturbed by ultrasound. This phenomenon is the result of interaction between light waves and acoustic waves in the medium. The acoustooptic effect provides an effective means to control the frequency, direction and strength of the laser beam. Acousto-optic devices made by acousto-optic effect, such as acoustooptic modulator, acousto-optic deflector and tunable filter, have important applications in laser technology, optical signal processing and integrated optical communication technology.
