ABSTRACT:
A raster input scanner (RIS) comprising a platen and light source, doubling mirror, lens and two CCD arrays for producing a bit stream output with twice the resolution produceable with a single CCD is disclosed. The doubling mirror is between the platen and lens, and produces two beams separated by a small angle. The lens focuses these beams as two lines at the image plane, where half of each intersects each CCD array. Glass plates, each intersecting and perpendicular to each beam, and rotatable about orthogonal axes, provide horizontal and vertical fine tuning.
