ABSTRACT:
A barcode scanning system is provided, which comprises an amplitude compensation circuit to change the amplitude of signals corresponding to each location on the barcode such that all the signals have the same amplitude. The changing of the amplitude may be determined according to an angular position or an oscillating velocity of an mirror. Preferably, the cutoff frequency of a low pass circuit in the barcode scanning system is variable according to the oscillating velocity or the angular position of the mirror too.
