Abstract. The problem of image transmission by a light beam under collinear diffraction of the beam on acoustic wave in crystal is considered. The law of image transformation, the transfer function, and other characteristics of collinear acousto-optical filter are derived for the general case; approximation of weak birefringence is not used.
