A system for imaging documents is provided, comprising (a) an image sensor; (b) at least one light source, the light source(s) being adapted to emit at least two different wavelengths of light; (c) means for capturing images of sequentially illuminated sections of a document passing in front of the image sensor under the illumination of a first wavelength, and images of sequentially illuminated sections of the document under the illumination of a second, different wavelength and (d) means for combining all of the imaged sections to produce an interleaved image of said document, or means for separating the imaged sections according to wavelength to produce individual images of said document under the illumination of the first and second wavelengths respectively, or means for combining the imaged sections illuminated under the first and second wavelengths into a single composite image of said document. |
