Abstract
Scanning devices and method of use that permit the capture of high resolution images of an original that is illuminated by a light source that is located outside of the optical field of view of an image detector. In one aspect, the image detector may be a monochrome sensor that sequentially captures different color plane images of an original that is illuminated by different colors. The different color plane images may be processed to generate a full color copy of the original. Light and images may be directed through tapered optical waveguides to minimize the volume of the scanning device. The image detector may include a first associated waveguide while the light source may include a second associated waveguide.
