By using an acousto-Optic effect, the direction of the output laser beam will be controlled without a mechanical moving parts.
Scanning of the laser beam or illuminating of the laser to the random direction within the angular range (⊿θ=⊿f×λ/v) are possible by modulating the frequency of the input RF signal.

*In this demonstration video, in order to facilitate viewing the operation of the AOD, it is operated at the modulation speed of 1 Hz.
