| 主权项 | 1. A method for detecting a document, the method comprising: moving the document in a first direction; capturing a first plurality of line scans of at least a portion of the document at a first wavelength of electromagnetic radiation; capturing a second plurality of line scans of at least a portion of the document at a second wavelength of electromagnetic radiation; assembling the first and second pluralities of line scans to form one or more images of at least portion of the document; and wherein at least a portion of the first plurality of line scans are captured substantially perpendicular to the direction of travel of the document. | ||
