APPARATUSES AND METHODS FOR DETECTING OPTICAL BARCODES

摘要

A barcode reader (124) for detecting a barcode (110) associated with a moving carrier (112) is proposed. The barcode reader (124) has at least one optical barcode detector for detecting information modules (116) of the barcode (110) at least in a one-dimensional manner. The barcode reader (124) also comprises at least one optical clock track detector for detecting clock track modules (130) of a clock track (128) of the barcode (110) and at least one optical reference detector for detecting at least one item of reference information relating to the barcode (110). The barcode reader (124) is set up to infer a direction of movement (120) of the carrier (112) from at least one signal from the clock track detector and at least one signal from the reference detector.
