摘要:
A multiple resolution scanner device (10) for scanning an object may comprise a first optical wave guide bundle (26) having a light input end (38), a light output end (40), and a first reduction ratio associated therewith. The light input end (38) of the first optical wave guide bundle (26) is arranged to receive image light from the object being scanned. A second optical wave guide bundle (28) having a light input end (48) and a light output end (50) has a second reduction ratio associated therewith that is different than the first reduction ratio associated with the first optical wave guide bundle (26). The light input end (48) of the second optical wave guide bundle (28) is arranged to receive image light from the object being scanned. A detector (30) positioned adjacent the light output ends (40, 50) of the first and second optical wave guide bundles (26, 28) receives image light from the light output ends (40, 50) and produces an image data signal (60) related to image light received from the light output ends (40, 50). An optical wave guide selection apparatus (58) operatively associated with the scanner device (10) selects an optical wave guide bundle (26, 28), the image light from which is used by the detector (30) to produce the image data signal (60).
