The problem of transforming an electrical video signal into an optical image using an acoustooptical cell with amplitude and ohase modulation of the acoustical wave is examined. Expressions are acquired for the space-frequency characteristics of the cell in cases of isotropic and anisotropic diffraction of light. It is shown that the maximal resolution of the cell is determined either by the band of tte piezoconverter or by the selective properties of acoustooptical interaction.
