A proposal is described for acoustic 2-D modification of optical mutual intensity. The use of two independent acoustic waves, progressing at right angles, produces the acoustically modified mutual intensity that varies in 2-D periodic manner. Since 2-D periodicity of the modified mutual intensity is recognized to be negligibly small within a circular object concerned, the computer-generated image pattern is almost uniform in the azimuthal direction of the image plane. The acoustically phase-modulated light illuminating the object forms an image whose ringing effect is appreciably suppressed. The rising of the image near its edge is superior to that for the incoherent limit.
