Low Resolution Deflectors & Variable Frequency Shifters

These AO devices have been optimized for a broader frequency range and permits either to have a variable frequency shifter or a low resolution but fast deflector.

Low Resolution Deflectors

An Acousto-optic deflector provides a spatial deflection of the diffracted order by varying the applied RF frequency. The Low-resolution version uses the Longitudinal mode configuration and provide faster scanning within smaller angles. The two key parameters to be considered latter is the number of distinct directions (Resolution) which can be addressed by the deflector and the Scan Angle.

Variable Frequency Shifters

The Acousto-optic interaction inherently introduces a frequency shift in the diffracted order. The amount of the frequency shift equals to the injected carrier frequency and it can be upshifted or downshifted depending on the selected input Bragg angle. A Variable Frequency Shifter is an Acousto-optic device whose carrier frequency has been adapted over a frequency range, hence providing variable frequency shifts. A Low Resolution Deflector shares the same properties as a Variable Frequency Shifter.
