Abstract
Bar code imagers and methods of operating bar code imagers are described herein. One method includes illuminating a bar code with a first illumination beam provided by the bar code imager device, wherein the first illumination beam has a first wavelength, and illuminating the bar code with a second illumination beam provided by the bar code imager device, wherein the second illumination beam has a second wavelength that is different than the first wavelength.
Claims18
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.
A method of operating a bar code imager device, comprising:
- illuminating a bar code with a plurality of illumination beams provided by a single illumination source of the bar code imager device, wherein illuminating the bar code with the plurality of illumination beams includes moving each of the plurality of illumination beams across the bar code from a first side of the bar code to a second side of the bar code at different times;
- wherein each of the plurality of illumination beams has a different modulation frequency.
A bar code imager device, comprising:
- a single illumination source configured to provide a plurality of illumination beams for illuminating a bar code by moving each of the plurality of illumination beams across the bar code from a first side of the bar code to a second side of the bar code at different times;
- wherein each of the plurality of illumination beams has a different wavelength and a different modulation frequency.
