Apparatus for producing data signals relating to light reflected by an illuminated object may include a fiber optic bundle having a plurality of optic fibers, each of the optic fibers having a light input end and a light output end. The light input ends of the optic fibers are substantially coplanar and are arranged adjacent one another in a generally linear configuration so that they define a line. The light output ends of the optic fibers are also substantially coplanar, but are arranged adjacent one another in a generally rectangular configuration so that they define a rectangle. Detector apparatus operatively connected to the light output ends of the optic fibers produces data signals that correspond to light received from the light output ends of the optic fibers.
