ABSTRACT:
A hologon scanner system in which a pair of laser beams which are collinear with each other are deflected by a common hologon scanner. The beams are initially linearly polarized in orthogonal directions and are combined in a polarization sensitive beam combiner so that they are collinear. The combined beams are passed through a quarter wavelength plate (the laser beams both being of the same wavelength) so as to circularly polarize them in opposite hands. The combined circularly polarized beams may be modulated to change their intensity. Such modulation may be provided by an acousto-optic diffraction grating modulator. The modulated beams are then directed to the hologon deflector and are scanned across the image surface. The modulator is also part of a closed loop feedback system with a detector which responds to positional variations of the image surface due to its transport system and deflects the beam to compensate for such position variations.
