Abstract: A flying spot scanning system is provided by utilizing reflected light from a multifaceted rotating polygon which is then directed to the scanned medium. A light source illuminates given facets of the polygon to provide the desired function of spot scanning. In each scanning cycle, information is transmitted to the scanned medium by modulating the light from the light source in accordance with a video signal. To assure an effective sequence of spot scans and the resulting scanning cycle, a beam splitter is employed to provide an unmodulated light beam from the original light beam which is directed at the illuminated facets of the polygon at an angle of incidence different from that of the incident modulated beam. An optically sensitive detector is aligned in relation to the scan width of the scanned medium so as to receive only the unmodulated beam during each scan cycle to determine the start/stop of each scan.

Abstract: Apparatus for placing an image on a photoreceptor by exciting a phosphorescent intermediate which then contacts the photoreceptor causing an image in the pattern of the excited phosphors on the intermediate. Apparatus may be added for viewing the image formed on the intermediate. By use of a long persistence phosphor, the intermediate is capable of several exposures on the photoreceptor though it is excited only once.

Abstract: A flying spot scanning system is provided by utilizing reflected light from a multifaceted rotating polygon which is then directed to the scanned medium. A light source illuminates at least one of the facets of the polygon during each scanning cycle to provide the spot scan. In each scanning cycle, information is transmitted to scanned medium by modulating the light from the light source in accordance with a video signal. To assure a uniform spot size at the scanned medium, an optical convolution of elements is selected in combination with the light source such that an adequate depth of focus at the medium is assured. An imaging lens is provided in series with a lens, which expands an original light beam, to converge the expanded beam to illuminate the selected facet or contiguous facets that are to control the movement of a spot throughout a scan angle. In the preferred embodiment, the rotation of the polygon is synchronized in phased relation to the scan rate used to obtain the video signal.

Abstract: An illumination system having four lamps arranged orthogonally around a subject to be illuminated with each lamp positioned outside the corresponding adjacent edge of the subject. A bireflector having cylindrical and/or ellipsoidal surfaces is associated with each of the lamps for directing light rays to the subject from the adjacent edge thereof to the edge opposite thereto.

Abstract: A machine for automatically making a plurality of superposed exposures optical input from a moving object cylinder carrying a document to a synchronously moving transparent electro-conductive image cylinder for forming the images. Internal to both the cylinders is an optical system for projecting contiguous portions of the object onto a plurality of locations on the image cylinder each in superposed registration. The optical systems are aligned such that a presentation of a point from the object to the image cylinder at one portion of the surface is repeated at the same portion of the surface after the surface has moved from its original position. The optical systems each have a skewed lens and a plane and roof mirror for projecting transferable images without keystone distortion. An embodiment uses the optical reimaging system for forming photoelectrophoretic images.

Abstract: An optical flying spot scanner having a lens array positioned between a scan line and a detector array and inclined at an angle to the axis of the scan line. Each of the lenses of the lens array has a coordinate position in a plane parallel to the scan line related to a particular segment of the scan line such that the information content of each segment of the scan line is transmitted to a different one of the tiered detectors of the detector array.

Abstract: A flat field scanning system is disclosed which has the following characteristics: (a) a stationary lens is located between a scanning mirror and a medium; (b) the mirror is moved linearly for scanning; (c) at the start of scan, a beam is directed from or received by the mirror substantially on axis of the lens; (d) the beam distance from the object plane of the lens to the lens and from the lens to the image plane of the lens always increases from the start of scan to the end of scan; and (e) during movement of the mirror, the mirror is pivoted to continue to reflect the beam through or receive the beam from the center of the lens. Linear movements are utilized in the scanning system eliminating the use of intricate cam surfaces.
