Abstract:
1. A method of operating a bar code imager device, comprising: illuminating a bar code with a first illumination beam provided by a single illumination source of the bar code imager device, wherein the first illumination beam has a first wavelength and illuminating the bar code with the first illumination beam includes moving the first illumination beam across the bar code from a first side of the bar code to a second side of the bar code; and illuminating the bar code with a second illumination beam provided by the single illumination source of the bar code imager device, wherein the second illumination beam has a second wavelength that is different than the first wavelength and illuminating the bar code with the second illumination beam includes moving the second illumination beam across the bar code from the first side of the bar code to the second side of the bar code at a different time than the first illumination beam.
