摘要： Scan exposure in a row or swath scanner is controlled by pulsing light sources with pulses (R, G, B) that are separated by dark intervals (441) from each other - and from the detector readout periods (RD). Detector sequencing is thereby made independent of the velocity of the pixel-line advance mechanism (401-403; 131, 133). Different pulse widths (412, 412') for different colors provide color correction without calculation, or regularize colorspace conversion calculations (128) where needed. In a swath scanner, known technology of printing modes is imported into the scanning context. Order of pixel columns within each swath can be reversed (251) for printing - permitting use of novel configurations such as a dual-parallel-flatbed copier (Figs. 13, 14) in which a single common scan-and-advance mechanism (211, 231-244') simultaneously transports the scan sensor (214) and printheads (212, 213). To produce mirror images, this configuration is also used without column reversal. In addition to red, green and blue light sources, an infrared source is used for reading invisible indicia that identify forms or media types. The scan sensor (214) is also used (214') for auxiliary printing functions.

摘要： In a system for scanning a document (43), a light source (22) illuminates the document; an imager (24, 41, 41', 61, 62) receives light from the document and directs it toward a detector array (25) which produces a corresponding array of electrical signals. The imager has several optical properties that are useful either individually or in combination. The imager is telecentric and thereby ensures that image size and magnification are insensitive to object displacement along the optical axis (46, 46') and image brightness is uniform independent of object off-axis distance. An aspheric element (33) within the imager balances focus variation (82-81-83) within the depth of field with spherical aberration and thereby provide nearly uniform image resolution. A diffraction pattern (33'), carried by the imager, corrects for spectral dispersion which occurs when light passes (63) from air into a refractive material (61, 62). An imager with a reflecting surface (32, 33) provides a system that is subject to little or no chromatic aberration. A solid imager (61, 62) with multiple internal reflecting surfaces (32, 33, 42) in optical series (32-33-32-42), configured to include the previously mentioned optical properties, also provides for highly stable alignment of reflecting surfaces.
