Abstract: In a document processing array, an imaging/illumination arrangement for illuminating and imaging the documents at one or several imaging-sites as they are rapidly transported there-past, each site having, as its illumination source, a hollow Lambertian integrating cylinder housing lamps which project essentially all their light onto the inner cylinder walls to be reflected/diffused thereby in Lambertian fashion and sent to the imaging site(s).

Abstract: An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.

Abstract: In a check processing array, an imaging/illumination arrangement for illuminating and imaging checks at one or several imaging sites as they are rapidly, continuously transported past two or more imaging stations, each station having, as its illumination source, a hollow Lambertian integrating vessel, housing lamps which project a highly uniform, diffuse Lambertian illumination-beam to its respective imaging site.

Abstract: A set of track gauges for use in aligning, focusing and normalizing an imaging system of a high speed document processor have been provided. Each of the gauges fit within a track (14) in front of the imaging system (10 or 12). The depth gauge (70) is used to align the secondary light beam (26) with the primary light beam (22) so that all documents passing through the track (14) will be evenly illuminated from two points symmetrically offset from a line normal to the track (14). In addition, the depth gauge (70) is used to align a normally reflected beam (32) with a photodetector array (56). Two different trunnion mirrors (54 and 28) are adjusted in the two different alignment operations. The focusing gauge (80) includes a set of black 87 and white 88 stripes positioned on a middle region 86. The white reference gauge (90) has a reflective white coating in its middle region 96.

Abstract: An arrangement for illuminating documents in a document-processing system wherein a large number of documents are rapidly and continuously transported past one or more imaging stations, each station having, for illumination, an integrating structure which houses one or more cylindrical, integrating Lambertian reflecting/diffusing cavities, each cavity having one or more like light sources, so that each cavity generates and projects a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating imaging camera means and optical guide means to couple the illumination beam to the face of the documents at the imaging station and to couple the image of the document to the imaging camera.
