ABSTRACT:
A barcode or similar scanning device is adjusted and calibrated by utilizing test pulses and measuring the peaks and calculating average of reflected light. The duty cycle of the pulses is adjusted based upon the measurements taken, in order to insure that the amount of reflected light is within the appropriate range associated with the charge coupling device or similar device collecting the reflective light.
