acousto-optics
Discipline within optical physics that addresses sound vibration, phonon effects and their influencing behavior within optical elements and systems.
A-O
acousto-optic
acousto-optic deflection
The angular change of an incident beam due to vibrational induced refractive index changes within a crystal.
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.
acousto-optic diffraction
Light diffracted by a solid (usually quartz in crystal or fused form) traversed by acoustic waves. If the ultrasonic wavelength is larger than the diameter of the light beam, the diffraction orders...
acousto-optic modulation
The altering of lightwaves by acoustic waves in a solid medium.
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 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...
acousto-optic tunable filter
A bulk crystalline optic which permits the propagation of light through a volume of index altered material. The variation in refractive index along the material volume is due to a piezoelectric...
acoustophotorefractive effect
The change in refractive index that occurs as acoustic vibrations are transmitted through an optical material.The index changes are periodic in relation to the frequency, spatial orientation, and...
