Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft ein Sehrohr, mittels welchem es dem Beobachter möglich ist, im Innern eines geschlossenen Raumes ein vollständiges Bild vom Horizont zu erzielen, und zwar durch Projektion des Bildes des Horizontes auf eine kegelstumpfförmige oder zylindrische Wandung einer Dunkelkammer, in welche der Kopf des Beobachters eindringen kann.The present invention relates to a periscope by means of which the observer can do so is to get a complete picture of the horizon inside an enclosed space, namely by projecting the image of the horizon onto a frustoconical or the cylindrical wall of a darkroom, into which the observer's head penetrates can.

ίο Der Erfindungsgegenstand ist beispielsweise in der beiliegenden Zeichnung dargestellt, und zwar in einem mittleren Längsschnitt.ίο The subject of the invention is for example shown in the accompanying drawing, in a central longitudinal section.

In dieser Zeichnung ist ι das Rohr, das an seinem oberen Ende für die Aufnahme der Lichtstrahlen des Horizontes ein kreisrundes, für totale Reflexion bestimmtes Objektiv 2 trägt, welch letzteres vom äußeren Horizont nach dem Rohrinnern ein ebenes ringförmiges Bild wirft. Dieses mit A bezeichnete Bild wird nach und nach mittels der konvergierenden Ringlinsen 3 und 4 weiter übertragen und endlich unter Verwendung eines Ringprismas 6 von totaler Reflexion auf die Wandung 5 von kegelstumpfförmiger oder zylindrischer Form projiziert, welche Wandung inner- halb der kreisrunden Dunkelkammer 7 angebracht ist. Das Bild kann nun durch Scheiben 9, die den Raum 8 begrenzen und in den der Kopf des Beobachters eindringen kann, direkt beobachtet werden.In this drawing, ι is the tube that carries a circular lens 2 intended for total reflection at its upper end for receiving the light rays of the horizon, the latter throwing a flat ring-shaped image from the outer horizon to the inside of the tube. This image labeled A is gradually transmitted by means of the converging ring lenses 3 and 4 and finally projected onto the wall 5 of frustoconical or cylindrical shape using a ring prism 6 of total reflection, which wall is attached inside the circular dark chamber 7 . The image can now be observed directly through panes 9 which delimit the space 8 and into which the observer's head can penetrate.
