Abstract
A bar code label scanning system comprises a light source for producing a light beam at a first wavelength which is swept across a bar code. Light from the bar code is passed through a filter for attenuating light scattered from said bar code to approximately a level of light emitted from a fluorescent ink, having an excitation wavelength equal to said first wavelength, in response to irradiation by said light beam. The filtered light is received and a signal representative of the amplitude of the filtered light is generated. The signal is decoded to provide a bit string encoded in said bar code.
