    Research output: Chapter in Book/Report/Conference proceedingConference contribution


    We achieved a significant extension of the depth of field for a laser-scanning barcode reader by wavefront coding with a cubic phase mask. If the present method is adopted in a laser-scanning barcode reader, a decrease in the frequency of reading failure is expected.
