Abstract

Les fibres optiques d'un écran plat à fibres optiques sont utilisées pour la prise de vues. Un faisceau lumineux explorateur, qui parcourt les fibres l'une après l'autre, est réfléchi par une surface pour documents placée avant la surface de l'écran et ramené par les fibres à un détecteur.The optical fibers of a flat screen with optical fibers are used for taking pictures. An explorer light beam, which traverses the fibers one after the other, is reflected by a document surface placed before the screen surface and brought back by the fibers to a detector.

Beschreibung description
Lichtleitfaser-Bildaufnehmer.Optical fiber image sensor.
Es sind Laserscanner-Bildaufnehmer bekannt, die ein Bild, z.B. auf Papier befindlich, derart in elektrische Information umwandeln, daß ein fokussierter Laserstrahl alle Bildpunkte nacheinander rasterförmig abtastet und daß das reflektierte Licht von einem Detektor in ein entsprechendes sequentielles Signal umgewandelt wird.Laser scanner image recorders are known which take an image, e.g. on paper, convert it into electrical information in such a way that a focused laser beam scans all the pixels one after the other in a grid pattern and that the reflected light is converted by a detector into a corresponding sequential signal.
Solche Laserscanner-Bildaufnehmer erfordern eine erhebliche Bautiefe der entsprechenden Abtastvorrichtung in Richtung senkrecht zur Bildfläche.Such laser scanner image recorders require a considerable depth of the corresponding scanning device in the direction perpendicular to the image surface.
Der Erfindung liegt die Aufgabe zugrunde, durch Verwendung der Lichtleitfaseranordnungen und Lichtablenkvorrichtungen von Flachbildschirmen Laser-Bildaufnehmer geringer Bautiefe zu ermöglichen.The object of the invention is to make it possible to use laser image recorders of low overall depth by using the optical fiber arrangements and light deflection devices of flat screens.
Die Verwendung von geordneten Lichtleitfaserbündeln zur Erzeugung von Flächenbildern durch Austritt des jeweils ein Bildelement darstellenden Lichtes aus jeweils einem Faserende und Erzeugung der entsprechenden Hell-Dunkel-Verteilung an den Lichteintrittsenden durch serielles Abtasten mit Laserstrahlen ist bekannt. Durch entsprechende Anordnung der Lichteintrittsenden und Auffächern der Lichtaustrittsenden ist eine flache Bauweise für solche Bildschirme möglich.It is known to use ordered optical fiber bundles to generate surface images by exiting the light representing a picture element from one fiber end and generating the corresponding light-dark distribution at the light entry ends by serial scanning with laser beams. By arranging the light entry ends and fanning out the light exit ends accordingly, a flat design for such screens is possible.
Dieselbe Faser-Lichtablenkvorrichtung, die das Bild entstehen läßt, kann als Bildaufnehmer oder interaktiver Bildschirm verwendet werden, wenn man das gebündelte Licht einer Bildaufnehmerlichtquelle sequentiell durch dieselben zur Bilderzeugung dienenden Fasern sendet. Das dann von einem vor dem Bildschirm plazierten Objekt reflektierte Licht durchläuft dann in umgekehrter Richtung dieselben zur Bilderzeugung dienenden Fasern oder nicht der Bilderzeugung dienende Sensorfasern in Richtung auf einen oder mehrere Detektoren, die sequentielle elektrische Signale erzeugen. The same fiber light deflecting device that forms the image can be used as an image recorder or interactive screen if the bundled light from an image pickup light source is sequentially transmitted through the same imaging fibers. The light then reflected from an object placed in front of the screen then passes in the opposite direction through the same imaging fibers or non-imaging sensor fibers towards one or more detectors that generate sequential electrical signals.
