Represents the XML element AcoustoOpticalDeflector.
Acousto-optic deflectors are devices which can be used to deflect a laser beam in one direction by a variable angle, controlled by the frequency of an electrical signal. Essentially, such a device is an acousto-optic modulator which is operated with an electrical drive signal of constant power but a variable frequency. The direction of the diffracted beam is determined by a Bragg condition, which contains the sound wavelength and thus depends on the sound frequency.
