Description

Optischer Entfernungsmesser Die Erfindung betrifft einen optischen Entfernutssesser. Optical range finder The invention relates to an optical rangefinder Distant eater.

Der optische Aufbau bekannter Entfernungemesser bedingt eine Bauform, die die Einsatzmöglichkeit dieser Meßinstrumente beschränkt.The optical structure of known rangefinders requires a design which limits the application of these measuring instruments.

Zur Behebung dieses nachteils wird gemäß der Erfindung ein optischer Entfernungsmesser einfacher Bauart vorgeschlagen, der entsprechend den in den Ansprilohen gekennzeichneten Maßnahmen ausgebildet ist.To remedy this disadvantage is an optical according to the invention Rangefinder of simple design proposed according to the requirements in the claims marked measures is designed.

In der Zeichnung ist schematisch ein Ausführungsbeispiel der Ertinduls dargestellt. Es zeigt Figur 1 den optischen Aufbau eines erfindungsgemäßen Entfernungsmessers, Figur 2 das sich dem Auge darbietende Einstellbild.In the drawing, an embodiment of the Ertinduls is schematically shown. It shows Figure 1 the optical structure of a range finder according to the invention, FIG. 2 the setting image presented to the eye.

Die Objektive 1 und 2 entwerfen je ein Bild, ton denen ii gezeigten Ausführungsbeispiel eines direkt und das anders über einen Spiegel 3 auf einen das Gesichtsfeld teilenden Spiegel 4 optisch abgebildet wird. In dem gezeigten Beispiel verläuft die des Geschichtsfeld teilende Kante des Spiegels 4 parallel zur Zeichenebene. Die Teilbilder auf dem Spiegel 4 werden mittels eines Objektives 5 optisch abgebildet und durch ein Okular 6 betrachtet. Im gezeigten Ausführungsbeispiel ist im Strahlengang des Objektives 2 ein bekanntes Planplattenmikrometer 7 zur Bildverlagerung vorgesehen. Durch Drehen der planparallelen Glasplatte 7 des Nikrometers wird erreicht, daß sich die zwei Ralbbilder des zu messenden Objektes 8 (Figur 2) zu einem Vollbild ergänzen. Dabei ist der Verschwenkbetrag der planparallelen Glasplatte 7 ein Maß fiir die Entfernung des Objektes 8.Lenses 1 and 2 each design an image, ton those ii shown Embodiment of one direct and that different over a mirror 3 is optically imaged on a mirror 4 dividing the field of view. By doing The example shown runs the edge of the mirror 4 dividing the historical field parallel to the plane of the drawing. The partial images on the mirror 4 are by means of a Objective 5 optically imaged and viewed through an eyepiece 6. Im shown The exemplary embodiment is a known plane-plate micrometer in the beam path of the objective 2 7 intended for image relocation. By rotating the plane-parallel glass plate 7 of the Nikrometer is achieved that the two Ralbbilder of the object to be measured 8 (Figure 2) to a full screen. The amount of pivoting is the plane-parallel Glass plate 7 a measure for the distance of the object 8.
