Abstract:
The basic constraints on the working range of CCD-based bar code readers are analyzed. A comprehensive model that allows the calculation of the optimal working range and its corresponding optical system parameters is derived. Experimental results are found to be in good agreement with theoretical calculations. Finally, comparisons between bar code laser scanners and CCD readers are presented.
