Abstract
A laser scanner for reading the Universal Product Code on grocery packages in a supermarket checkout lane is described. The problems associated with reading five sides (bottom and four sides) of a package are discussed in terms of the bit-rate, spot-size, and angle of incidence variations in different orientations. The optics, detection, signal processing, and decoding are also described.
