  • Acousto-optic modulator — An acousto optic modulator (AOM), also called a Bragg cell, uses the acousto optic effect to diffract and shift the frequency of light using sound waves (usually at radio frequency). They are used in lasers for Q switching, telecommunications for …   Wikipedia

  • Acousto-Optic Deflector — Acousto Optic deflectors= An acousto optic deflector spatially controls the optical beam. In the operation of an acousto optic deflector the power driving the acoustic transducer is kept on, at a constant level, while the acoustic frequency is… …   Wikipedia

  • Electro-optic modulator — (EOM) is an optical device in which a signal controlled element displaying electro optic effect is used to modulate a beam of light. The modulation may be imposed on the phase, frequency, amplitude, or direction of the modulated beam. Modulation… …   Wikipedia
