Beschreibungdescription
Visiereinrichtung Die vorliegende Erfindung betrifft eine Visiereinrichtung mit einer in den Strahlengang zwischen Beobachter und Beobachtungsgegenstand eingebrachten, zumindest teilweise durchsichtigen Markierungsanordnung mit veränderbaren Markierungen.Sighting device The present invention relates to a sighting device with one placed in the beam path between the observer and the object to be observed, at least partially transparent marking arrangement with changeable markings.
Es ist bekannt, in den Strahlengang von Visiereinrichtungen, wie z. B. Zielfernrohre, Hilfsmarkierungslinien einzubringen, die das Anpeilen eines Beobachtungsgegenstandes erleichtern. Bekannte Markierungslinien dieser Art sind z. B. das Fadenkreuz und konzentrische Ringe.It is known, in the beam path of sighting devices such. B. Rifle scopes to introduce auxiliary marking lines, the sighting of an object of observation facilitate. Known marking lines of this type are z. B. the crosshairs and concentric rings.
Es ist häufig erwünscht, daß je nach Art des anzuvisierenden Beobachtungsgegenstandes unterschiedliche Markierungslinien in den Strahlengang eingebracht werden, z. B. um das Anvisieren von näher oder weiter entfernten Gegenständen zu erleichtern bzw. um zusätzliche Einflüsse, wie z. B. Windgeschwindigkeit usw. berücksichtigen zu können.It is often desirable that, depending on the type of observation object to be targeted different marking lines are introduced into the beam path, e.g. B. to make sighting of objects closer or farther away easier or to avoid additional influences, such as B. wind speed etc. to be taken into account can.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Visiereinrichtung anzugeben, die das Einblenden unterschiedlicher Hilfsmarkierungen in den Strahlengang ermöglicht.The present invention is based on the object of a sighting device indicate the fading in of different auxiliary markings in the beam path enables.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorge schlagen, daß die Markierungsanordnung eine Flüssigkristallzelle vom Typ der dynamischen Streuzelle aufweist, deren auf transparenten Deckplatten befindliche transparente Steuerelektroden zumindest auf einer Deckplatte in Form der gewünschten Markierungen ausgebildet und getrennt ansteuerbar sind.To solve this problem, propose according to the invention, that the marking arrangement is a liquid crystal cell of the dynamic scattering cell type has, the transparent control electrodes of which are located on transparent cover plates formed at least on a cover plate in the form of the desired markings and can be controlled separately.
Ein wesentlicher Vorteil der erfindungsgemäßen Visiereinrichtung besteht darin, daß in einfacher Weise eine Anpassung von Hilfsmarkierungen an die jeweiligen Begleitumstände ermöglicht wird. So ist es z. B. in einfacher Weise möglich, Radarinformationen, die in Form von elektronischen Signalen zur Verfügung stehen, direkt zur Ansteuerung der Flüssigkristallzelle heranzuziehen, wodurch die Bedienung der Visiereinrichtung wesentlich vereinfacht wird.There is a significant advantage of the sighting device according to the invention that in a simple manner an adaptation of auxiliary markings to the respective Accompanying circumstances is made possible. So it is z. B. possible in a simple way to provide radar information, which are available in the form of electronic signals, directly for control to use the liquid crystal cell, whereby the operation of the sighting device is simplified significantly.
Anhand der in den Figuren 1 und 2 dargestellten Ausführungsbeispiele wird die Erfindung nachfolgend näher erläutert.On the basis of the exemplary embodiments shown in FIGS. 1 and 2 the invention is explained in more detail below.
In der FIG. 1 ist eine in den Strahlengang zwischen Beobachter 1 und einem Gegenstand 10 in eine Visiereinrichtung eingebrachte Markierungsanordnung dargestellt, deren wesentlicher Bestandteil aus einer Flüssigkristallzelle vom Typ der dynamischen Streuung besteht. Die Flüssigkristallzelle besteht z. B. in bekannter Weise aus zwei gläsernen Deckplatten 2 und 3, die in einem geringen Abstand zueinanderstehen und am Rand z. B. durch eine Vergußmasse 7 miteinander verbunden sind. Auf den sich zugewandten Oberflächen der Deckplatten 2 und 3 befinden sich in bekannter Weise transparente Elektroden 5 und 6. Im allgemeinen wird eine Elektrode eine durchgehende Schicht sein, während die andere Elektrode aus einer Vielzahl von einzelnen getrennt ansteuerbaren Elektrodenteilen besteht.In FIG. 1 is one in the beam path between observer 1 and an object 10 introduced into a sighting device marking arrangement shown, the essential part of which consists of a liquid crystal cell of the type the dynamic spread. The liquid crystal cell consists e.g. B. in known Way from two glass cover plates 2 and 3, which are at a short distance from each other and at the edge z. B. are connected to one another by a potting compound 7. On the himself facing surfaces of the cover plates 2 and 3 are in a known manner transparent electrodes 5 and 6. In general, one electrode becomes a continuous one Be layer while the other electrode is separated from a plurality of each controllable electrode parts exists.
Die einzelnen Elektrodenteile bestimmen die Form der einblendbaren Markierungen. Z. B. können diese Elektroden, wie in FIG. 2 dargestellt, die Form von Kreisen 22 und die Form eines Fadenkreuzes 21 aufweisen.The individual electrode parts determine the shape of the fade-in Markings. For example, as shown in FIG. 2 illustrated the shape of circles 22 and the shape of a crosshair 21.
Gemäß einer Weiterbildung der Erfindung ist die Flüssigkristallzelle dicht benachbart zu einer Lichtleiteranordnung 8 angebracht bzw. mit dieser verbunden, in welche von außen Licht eingestrahlt wird. Es ist in dieser Weise möglich, daß die entsprechend elektrisch angesteuerten Bereiche der Flüssigkristallanordnung als hell leuchtende Linien oder dergleichen in Erscheinung treten, während die nicht angesteuerten Bereiche der Flüssigkristallzelle durchsichtig bleiben. Das Flüssigkristallmaterial zwischen den Deckplatten 2 und 3 bzw. zwischen den Elektroden 5 und 6 ist mit 4 bezeichnet. Es kann auch zweckmäßig sein, die Flüssigkristallzelle selbst oder Teile davon, wie z. B.According to a further development of the invention, the liquid crystal cell is mounted close to or connected to a light guide arrangement 8, into which light is radiated from outside. It is possible in this way that the corresponding electrically controlled areas of the liquid crystal arrangement appear as bright lines or the like, while those do not controlled areas of the liquid crystal cell remain transparent. The liquid crystal material between the cover plates 2 and 3 or between the electrodes 5 and 6 is indicated by 4 designated. It can also be expedient, the liquid crystal cell itself or parts of it, such as B.
eine oder beide Deckplatten, als Lichtleiteranordnung zu verwenden.one or both cover plates to be used as a light guide arrangement.
Gemäß einer weiteren zweckmäßigen Ausführungsform der Erfindung befindet sich vom Beobachter 1 aus gesehen hinter der Flüssigkristallanordnung noch eine Blende, die bei dem dargestellten Beispiel als Jalousieblende 9 ausgebildet ist.According to a further advantageous embodiment of the invention is located Seen from the observer 1, there is another one behind the liquid crystal arrangement Aperture, which is designed as a louvre shutter 9 in the example shown.
