Аннотация

Methods for the calculation of the acousto-optic (AO) transfer functions forming as a result of superposition of two AO fields with similar and orthogonal light polarizations are proposed. Specific calculations are made on the basis of the parameters widely used in practice with uni-axial gyrotropic crystal paratellurite. It is revealed that the resulting field is generally very inhomogeneous but contains domains with two-dimensional behavior properties. These domains can be used for two-dimensional image edge enhancement based on Fourier processing. Theoretical conclusions are verified by means of the optical image Fourier processing with the spatial frequency AO paratellurite filters.
