ABSTRACT:
A color document scanner is achieved using three optical fiber bundles. Each bundle is linear at the entrance face and merely gathered at the exit face. The linear ends are abutted against one another and aligned across a document to be scanned. The (three) exit faces are abutted against one or more associated sensor arrays with, for example, red, green, and blue filters interposed between the fiber bundles and the sensor array(s). The sensor arrays are operative not only to relate the positions of fibers in the entrance and exit faces of the respective bundles, but also to organize the associated color information with the appropriate scanned line segment.
