Abstract

Bar arrangements used by conventional diffractive barcodes are usually similar to those used by diffusive barcodes. We, however, propose a modified diffractive barcode with bar arrangements different from those used by diffusive barcodes. A modified diffractive barcode pattern is composed of many parallel grating-dot lines. When the grating-dot lines are scanned by a laser beam in sequence, different bright bar arrangements corresponding to different codes appear in sequence.
