Abstract
Optischer Bild-Scanner mit einer Strahlführung durch einen Lichtleiter zur Erfassung großer Objekte, bei der die Detektionsobjekte bewegt werden, vorzugsweise Unterbodenkontrolleinheiten, die bei geringer Bauhöhe die statische und dynamische Last der Fahrzeuge ohne eine darüber liegende Trägerkonstruktion aufnehmen und die auftretenden Kräfte in das Fundament ableiten können, dadurch gekennzeichnet, dass im Blickbereich der Kamera Lichtübertragungselemente aus organischem Glas vorzugsweise als durchgängige Platte (5) zwischen Kamera (2) und Umlenkeinrichtung (6, 8) angeordnet sind und die notwendige Umlenkeinrichtung in diese lichtdurchlässige Platte integriert wird, indem die Abschlusskante der Platte nicht senkrecht, sondern in einem geeigneten Winkel - an dem Totalreflexion auftritt - geschnitten und in geeigneter Weise bearbeitet ist.Optical image scanner with a beam guide through a light guide for detecting large objects, in which the detection objects are moved, preferably underbody control units that record the static and dynamic load of vehicles without an overlying support structure and derive the forces occurring in the foundation at low height can, characterized in that in the field of view of the camera light transmission elements made of organic glass preferably as a continuous plate (5) between the camera (2) and deflection (6, 8) are arranged and the necessary deflection is integrated into this translucent plate by the end edge of the Plate not perpendicular, but at a suitable angle - occurs at the total reflection - cut and processed in a suitable manner.
Description
Die Erfindung hat den konstruktiven Aufbau eines optischen Bildscanners mit einer oder mehreren Zeilenkameras mit einer vorteilhaften optischen Strahlführung durch einen Lichtleiter zum Inhalt mit dem eine kompakte Ausführung der Vorrichtung ermöglicht wird.The Invention has the structural design of an optical image scanner with one or more line scan cameras with an advantageous optical beam guidance a light guide to the content with the a compact design of Device allows becomes.
Ein
Bildscanner zur Erfassung großer
Objekte, bei der die Detektionsobjekte bewegt werden ist in der
Die Aufgabenstellung für die Erfindung besteht in der konstruktiven Lösung eines flachen, transportablen (mobilen) optischen Bildscanners für die Unterbodenkontrolle von Fahrzeugen, die von den Fahrzeugen auch ohne Beschädigung überfahren werden kann.The Task for The invention consists in the constructive solution of a flat, transportable (mobile) optical image scanner for underfloor control of Vehicles that run over by the vehicles without damage can be.
Die kritische Größe für die konstruktive Lösung war die Strahlführung über den Umlenkspiegel bis zu einer Breite von drei Metern.The critical size for the constructive solution was the beam guide over the Deflecting mirrors up to a width of three meters.
Die
erfindungsgemäße Lösung wurde
derart gefunden, daß im
Bereich des Blickwinkels der Zeilenkamera ein lichtdurchlässige Körper aus
organischem Glas bzw. eine lichtdurchlässige Platte aus organischem
Glas (
Nach den Erfordernissen der Statik sind alle übrigen Bereiche des Raumes der Unterbodenkontrolleinheit mit Leichtmetallprofilen, Gitterrosten, hochverdichtetem Schaumstoff oder anderem Material ausgefüllt. Als Abdeckung kann eine nur wenige mm starke Metallplatte dienen, welche die von den Reifen der Fahrzeuge ausgeübten Kräften auf größere Bereiche der Füllkonstruktion verteilt.To The requirements of statics are all other areas of the room the underbody control unit with light metal profiles, gratings, high density Foam or other material filled. As a cover, a only a few mm thick metal plate serve that of the tires the vehicles exercised forces on larger areas the filling structure distributed.
Für die optimale konstruktive Gestaltung der lichtdurchlässigen Platte sind weitere Lösungen, wie in den Ansprüchen 1 – 5 beschrieben notwendig, so das Integrieren der Umlenkeinrichtung durch schrägen Anschnitt der Platte für eine Totalreflektion, die Vermeidung unerwünschter Reflektionen an den Seiten der Platte durch Aufrauhen und/oder Schwärzen der Seiten der Platte, die Unterdrückung von unerwünschtem Fremdlicht entsprechend der Arbeitswellenlänge durch Einfärben des organischem Glases der lichtdurchlässigen Platte, die Minimierung der Stärke der lichtdurchlässigen Platte entsprechend dem Strahlendurchgang und das Beschichten der Lichteintritts- und Lichtaustrittsflächen der lichtdurchlässigen Platte zur Vermeidung unerwünschter Reflexionen.For the optimal constructive design of the translucent plate are more Solutions, as in the claims 1 - 5 described necessary, so the integration of the deflection by oblique Bleed the plate for a total reflection, the avoidance of unwanted reflections on the Sides of the plate by roughening and / or blackening the sides of the plate, the oppression unwanted Ambient light corresponding to the working wavelength by coloring the translucent plate organic glass, minimizing the strength the translucent Plate according to the beam passage and the coating of the light entrance and light exit surfaces of translucent Plate to avoid unwanted Reflections.
Für bestimmte
Einsatzfälle
ist es notwendig, den Blickwinkel der Kamera in unterschiedlichen Sichtebenen
anzuordnen, dazu ist nach
Mit
der erfinderischen Lösung,
den Strahlengang über
eine optisch transparente Platte aus organischem Glas (
Die
hier beschriebene auf eine flache optische Unterbodenkontrolleinrichtung
bezogene Lösung,
den Strahlengang einer Zeilenkamera (
Diese Lösung ist beispielsweise für die Erfassung von Abbildungen von Gegenständen in automatisierten technologischen Abläufen und überall dort, wo von bewegten Gegenständen bzw. Objekten Abbildungen zur Kontrolle oder zur Steuerung benötigt werden, jeweils modifiziert anwendbar.These solution is for example the capture of images of objects in automated technological procedures and everywhere, where of moving objects or objects mappings needed for control or control, each modified applicable.
Die erfindungsgemäße Lösung nach den Ansprüchen 1 – 8 war die Voraussetzung für die Entwicklung einer transportablen (mobilen) Unterbodenkontrolleinrichtungen nach der Patentanmeldung 100 38 731.4 mit seinen Zusatzpatenten.The according to the invention solution the claims 1 - 8 was the requirement for the development of a portable (mobile) underbody control equipment according to the patent application 100 38 731.4 with its additional patents.
