Description

Optimierung eines Verfahrens zur tSittelpunktsmodulation in optischen Trackern Die Zusatzerfindung betrifft die Verbesserung der optischen Anordnung nach Patentantrag vom 15.4.72, Aktenzeichen P 2226372.5, Ausführungsbeispiel mit gefaltetem Strahlengang, Figur lb, Wenn für diese Anordnung ein Dachkantspiegel oder -prisma (wie in Anspruch 2 dargelegt) verwendet wird, ergeben sich Abscha,ttungen der Apertur durch die im Strahlengang des optischen Systems angeordneten Bauteile.Optimization of a method for center point modulation in optical Trackers The additional invention relates to the improvement of the optical arrangement Patent application from April 15, 1972, file number P 2226372.5, embodiment with folded Beam path, figure lb, if a roof mirror or prism for this arrangement (as set out in claim 2) is used, there are sections of the aperture by the components arranged in the beam path of the optical system.

Der Zusatzerfindung liegt die Aufgabe zugrunde, die optische Anordnung des vorgenannten Patentantrages, Figur b,zu optimieren.The additional invention is based on the task of the optical arrangement of the aforementioned patent application, Figure b, to optimize.

Diese Aufgabe wird erfindungsgemäS dadurch gelöst, daß in den Strahlengang ein Umlenkspiegel angeordnet wird, der einen Durchbruch zum Durchlaß der an dieser Stelle auftretenden Apertur erhält, welche an dieser Stelle bezogen auf die am Spiegel reflektierte Apertur äußerst klein ist.This object is achieved according to the invention in that in the beam path a deflection mirror is arranged, which has a breakthrough for the passage of this The aperture that occurs at this point is based on the one on the mirror reflected aperture is extremely small.

Der mit dieser Erfindung erzielte Vorteil besteht insbesondere darin, daß eine minimale Abschattung von wenigen Prozent erreicht werden kann und demzufolge der Wirkungsgrad des Systems entsprechend verbessert wird.The advantage achieved with this invention consists in particular in that a minimal shadowing of a few percent can be achieved and consequently the efficiency of the system is improved accordingly.

Ein Ausftihrungsbeispiel der Zusatzerfindung ist in einer Zeichnung dargestellt und wird im Folgenden näher beschrieben, Die Figur 1 zeigt eine solche Anordnung: 1) Eingangsobjektiv 2) Umlenkspiegel 3) Dachkantspiegel (Dachkantprisma) 4) Polygonalprisma 5) Bildebene Die durch das Eingangsobjektiv eintretende parallele Strahlung gelangt als konvergentes Bündel auf den Umlenkspiegel, von hier aus auf den Dachkantspiegel, welcher die Bilddrehung hervorruft.An exemplary embodiment of the additional invention is in a drawing and is described in more detail below, FIG. 1 shows one such Arrangement: 1) Entrance lens 2) Deflecting mirror 3) Roof edge mirror (Roof prism) 4) Polygonal prism 5) Image plane The through the input lens incoming parallel radiation arrives as a convergent bundle on the deflecting mirror, from here to the roof mirror, which causes the image to rotate.

Dieser wirft das Bündel zurick auf das Polygon an dessen Kante sich die bildebene befindet.This throws the bundle back onto the polygon at its edge the image plane is located.
