Paper Abstract

The comparative performance analysis for single-dimensional and two-dimensional acousto-optic deflectors is presented. A new generalizing parameter equal to the product between the number of resolvable spots and acousto-optic diffraction efficiency is proposed. The possibility to use self-collimating modes in crystals for two-dimensional deflectors is discussed. A new geometry for a two-dimensional deflector with coinciding acoustic beams is proposed. This geometry is based on the deviation of energy transmission direction from the wave normal. The experimental test results for the TeO2 two-dimensional deflector with coinciding acoustic beams are presented. The test results are in good agreement with estimations.
