Abstract
A scanner for scanning items marked with near-infrared tags includes a laser configured to produce a narrowband near-infrared beam matched to a peak wavelength of near-infrared ink used to print the tags. A mirror assembly re-directs the beam. A deflecting arrangement receives the re-directed beam. A steering mirror steers the deflected beam. A scanning mirror directs the beam onto the tag to be scanned and a light collection system collects light reflected by the tags.
