Abstract
A barcode scanner includes a light source for producing a scan line of light on a 2-D barcode along one of the two axes thereof. The scan line is scanned across the barcode along the other axis to effect a scanning band extending over the barcode in both of the two axes. Light reflected from the barcode is collected with a photodetector array to produce signals which are processed for decoding the barcode in both axes.
