Glossary

acousto-optic modulator A device that varies the amplitude and phase of a light beam; e.g., from a laser or by sound waves. Also known as a Bragg cell.
acousto-optic deflector A system designed with a laser as a light source and a means for producing sound waves extending beyond 100 MHz to deflect light efficiently.
modulator A modulator is a device or component that modifies a carrier signal in order to encode information for transmission over a communication channel. The process of modulating involves varying one or more properties of the carrier signal, such as its...
acousto-optic modulators and deflectors An acousto-optic modulator (AOM) is a device that utilizes the interaction between sound waves and light waves to modulate or control the intensity, frequency, phase, or direction of laser beams. It consists of a crystal or medium through which the...
