The code symbols form a rectangular field, and code symbols are transverse to the axis of their movement. A light beam is periodically deflected in the direction of symbol movement and at a right angle to it, so that a sinusoidal track segment is generated in the reading field for each period. Consecutive segment phases are shifted by a controlled amount. Deflectors have two mirrors in the light beam path, and two drives; the first mirror deflects the light beam along the window, and the second across it, so that a sinusoidal line is traced.
