ABSTRACT:
An optical printer, suitable for use in printing upon a recording medium, includes a tubular compensator disposed between a print head and the recording medium. The print head directs an elongated exposing beam through the compensator to impinge upon the medium, and the beam effects a line exposure across the medium. A transport device introduces relative motion between the medium and the print head during a line exposure by the beam. The relative motion is perpendicular to the exposure line and introduces a smear to each exposure line as well as an overlap between exposure lines. The tubular compensator includes inner and outer cylindrical surfaces having centers of curvature displaced relative to each other resulting in a wedge-like cross-section to a wall of the tubular compensator. The wedge angle varies with rotation of the compensator to provide for a linear deflection of the beam during a line exposure by the beam, thereby offsetting the advancement of the medium during the line exposure.
