Ultra Sound Technology for Reading Barcodes
A Norwegian company has created a patented technology based on ultra sound that can effectively read Data Matrix codes covered by paint, dirt or corrosion. The LOCUS ultra sound reader was created specifically for direct part mark (DPM) Data Matrix barcodes. The picture at the left shows what a dot peen Data Matrix code covered in spray paint looks like when read by the LOCUS Reader. A thanks to Kevin from the Ohio University AIDC Lab for the heads up on this cool technology.
