Abstract
Apparatus for use in an optical scanner for accurately controlling, from scan to scan, the position in which the horizontal scan line is formed. A closed electrooptical feedback loop is employed to sense, prior to the formation of each horizontal scan line, the vertical position of the scanning light beam in the plane of the recording element and, in the event its position is displaced from a nominal position, to produce an error signal to move the beam to the nominal position.
