Abstract
A color raster scanner includes separate optical paths including a resolution aperture for resolution imaging and a separate, larger screen aperture for large area imaging; each aperture receiving the reflected source chart image through common collection optics including a combination objective lens and collimating optics which extend the optical length to provide increased gain magnification of the sensed image into the objective image plane; the image from the collection optics being presented by relay optics which divide the image into the two separate apertures, at different gain magnification values (field stop to provide the resolution aperture with the major portion of the available light flux, the larger diameter value of the screen aperture allowing it to receive the minor portion of the available flux at a relatively consistent spectral intensity.
