Acousto-Optic Deflectors
Brimrose Acousto-Optic Deflectors (AODs) combined with RF drivers are specially designed for high-speed scanning applications such as laser recording, optical scanning, signal processing, etc.
The AOD changes the diffraction angle of an input laser beam and its angular position is linearly proportional to the RF frequency, so that the higher the frequency, the larger the diffracted angle.
Brimrose offers a large variety of variable frequency RF drivers compatible with our deflectors. The most commonly
used are VCO (Voltage Controlled Oscillator) type and computer-controlled direct digital synthesizers. By altering
the RF drive frequency to the AOD, the deflection angle is varied.
