In a rotatable mirror arrangement for generating a scanning beam which is displaced in steps parallel to itself a plurality of plane mirrors (11 to 16) are arranged in a helically displaced arrangement around a body (18) rotatable about an axis of rotation (17). The plane mirrors, which are of the same size are illuminated at an angle .alpha. by a light beam (19). The light beam (19) extends in a plane which contains the scanning beam and which lies parallel to but is displaced from the axis of rotation (17).
