ABSTRACT:
A system and method for independently controlling the collimation and lateral positioning of a light beam comprises at least one acousto-optic deflector and a pair of counter propagating acoustic waves with offset frequencies. While the frequency offset controls the lateral positioning of the light beam, a frequency gradient across the acousto-optic deflectors controls the collimation of the light beam.
