Abstract: Method and apparatus for improving the efficiency and resolution of laser scanning systems using a multi-faceted rotating polygon as the scanner device. In particular, an acousto-optic Bragg cell is utilized as an active optical element to both modulate, in response to an electrical input signal, and deflect an incident laser beam so that the modulated beam is caused to follow, or track, one facet of the scanner during a complete scan and to shift to the adjacent facet for the following scan. The scanning system is operated in a manner wherein during recording the image of the acoustic pulses at the surface of a recording medium are made to move at the same relative velocity, in the opposite direction, as the velocity of the laser recording, or write beam whereby imaging of the input electrical signal on the recording medium surface is accomplished without blurring.

Abstract: A digital facsimile scanning system in which transitions in alternate lines are shifted by sub-multiple clock pulse intervals. The sampling time, i.e. the time for sampling either black or white information bits is staggered on every two or more sweeps, to reduce the occurence of clouded patterns and to give an appearance of increased resolution.

Abstract: A device providing high resolution readout of information stored on a film. A slit equal in width to the desired spot size diameter is placed in front of a moving film. A fiber optics strip is placed in back of the film in line with the slit. A beam of light scans across the slit. The fiber optics strip is comprised of a plurality of optic fibers. The width of each fiber is also equal to the desired spot size diameter. All of the optic fibers are connected to a small group of photodetectors. The fibers and the detectors are arranged in such a manner that no one detector will receive information from more than one fiber at any one time as the beam scans across the slit.

Abstract: A scanning device includes a transparent platen which receives a sheet to be scanned. A backing assembly is spaced from the platen by the sheet during scanning. The backing assembly includes a backing plate of a fixed color and an electrochromic layer intermediate the backing plate and the platen. The electrochromic layer has a first state in which the electrochromic layer is opaque and has a different color from the fixed color, and a second state, in which the electrochromic layer is transparent to expose the backing plate through it. A sensor is positioned to acquire an image of the sheet based on light passing through the platen. A controller selectively applies a voltage across the electrochromic layer to change the electrochromic layer between the first and second states.

Abstract: In one example, a method for glare and shadow mitigation by fusing multiple frames includes illuminating the target with light from a first illumination direction and capturing a first frame of the target with a camera while the target is illuminated in the first illumination direction. The method also includes illuminating the target with light from a second illumination direction and capturing a second frame of the target with the camera while the target is illuminated in the second illumination direction. The first frame and second frame are fused together to form a composite image that simultaneously mitigates glare and shadow areas.
