ABSTRACT:
A multiple resolution scanner device for scanning an object may comprise a first optical wave guide bundle having a light input end, a light output end, and a first reduction ratio associated therewith. The light input end of the first optical wave guide bundle is arranged to receive image light from the object being scanned. A second optical wave guide bundle having a light input end and a light output end has a second reduction ratio associated therewith that is different than the first reduction ratio associated with the first optical wave guide bundle. The light input end of the second optical wave guide bundle is arranged to receive image light from the object being scanned. A detector positioned adjacent the light output ends of the first and second optical wave guide bundles receives image light from the light output ends and produces an image data signal related to image light received from the light output ends. An optical wave guide selection apparatus operatively associated with the scanner device selects an optical wave guide bundle, the image light from which is used by the detector to produce the image data signal.
