Definitions

  • the invention relates to a line scanner.
  • a disadvantage of both methods is that a flat design is not possible for reasons of optical imaging.
  • the object of the invention is to realize a line scanner - flat design.
  • the document line image dot by pixel is illuminated with a laser.
  • This sequential illumination is achieved in that an optical fiber leads to each pixel, which is connected to the others in an optical fiber band in the manner of a flat cable.
  • the laser beam is directed into the light entry ends of the optical fibers, which are formed into a circle, in the center of which a rotating mirror rotates, the axis of rotation of which coincides with the normal to the circular surface.
  • the rotating mirror surface is inclined 45 degrees to the axis of rotation, so that the laser beam striking the mirror axially is deflected radially towards the light entry ends of the fibers.
  • the light reflected from the document is directed by the same fiber through which it came to a photodiode located near the mirror axis.
  • Another possibility is to feed the reflected light to the photodiode through a second optical fiber band, the light-receiving ends of which are located close to the row of illuminating fiber ends of the first band, and whose other ends are shaped into an area of the smallest possible size instead of a row.
  • a laser beam guided by a single face turning mirror in the light entrance ends arranged circularly of optical fiber illuminates sequentially an image surface arranged quite close in front of the light outlet ends arranged for one line. Th light which is reflected may be brought to a detector.
  • Laser light directed from a single-surface rotating mirror into the circularly arranged light entry ends of optical fibers sequentially illuminates an image surface placed close to the light exit ends arranged in a row.
  • the reflected light can be directed to a detector. ONLY FOR INFORMATION

Abstract

Un rayon laser guidé par un miroir tournant uniface dans les extrémités d'entrée de lumière disposées circulairement de fibres optiques éclaire séquentiellement une surface d'image placée tout près devant les extrémités de sortie de lumière disposées pour une ligne. La lumière réfléchie peut être amenée à un détecteur.
