Optical method and apparatus for inspecting documents |
摘要 |
Document inspection apparatus comprises a document transport system (1) for transporting documents through a detector station (6). A linear array of separately activatable light sources (14, 15) at the detector (12) receives light transmitted through or reflected by any of the illuminated portions of the document and generates a corresponding output signal. A control system (9) sequentially activates the light sources and monitors the output signals from the detector.
