Signal ausgelöst wird.Signal is triggered.
Die Scktoroptiken 3' bis 3X" sind mit entsprechend vielen I jchtlcilern4' bis4x" verbunden, die die einfallende Strahlung 10' bis 10x" empfangen. Da die Länge der I iichtlcilcr von z. B. 30 cm des Lichtleiters 41 bis 360 cm r> des Lichtleiters 4XM kontinuierlich verlaufend abgestuft ist, gelangt jeweils Strahlung der maximal angestrahlten Sektoroptik über die Sammellinse 12 auf die lichtempfindliche Zelle 13 und von hier, nach entsprechender optoelektronischer Umwandlung, über den Verstärker to 14 und einen zweiten Eingang der Auswerteeinrichtung 8 in den Zähler 9, der daraufhin angehalten wird.The sector optics 3 'to 3 X "are connected to a corresponding number of Ijchtlcilern4' to 4 x ", which receive the incident radiation 10 'to 10 x ". Since the length of the Iights of, for example, 30 cm of the optical fiber 4 1 to 360 cm r > of the light guide 4 XM is stepped continuously, radiation from the maximum illuminated sector optics reaches the light-sensitive cell 13 via the converging lens 12 and from here, after appropriate optoelectronic conversion, via the amplifier to 14 and a second input of the evaluation device 8 into counter 9, which is then stopped.
Aus der Zeitdifferenz dieses Signals gegenüber demjenigen der Rundumoptik 2,11 bestimmt sich die Richt U η g a u f der A nzeige 15.The direction is determined from the time difference between this signal and that of the all-round optics 2, 11 U η g on display 15.
Zwischen die Sammellinse 12 und einen drillen Eingang der Auswerteeinrichtung 9 kann — der Reihe nach — noch ein dritter sich aus lichtempfindlicher Zelle 16 und Verstärker 17 zusammensetzender Kanal geschallet sein, der aus Rücksicht auf ein mögliches Überstrahlen des Kanals 13,14 nur einen Bruchteil, z. B. '/woo, der Empfindlichkeit dieses Kanals aufweist. Die Impulsslärkc über die Rundumoplik 2,11 mit Zelle 6 und Verstärker 7 schallet über die Auswerteeinrichtung 8 bei kleiner Energie die Zelle 13 und den Verstärker 14 ein, während bei großer Energie die Zelle 16 und der Verstärker 17 zur Auswertung geschaltet werden.Between the converging lens 12 and a three-way entrance of the evaluation device 9 can - one after the other - be a third consisting of a light-sensitive cell 16 and amplifier 17 composing the channel to be sounded out of consideration of possible overexposure of the channel 13,14 only a fraction, e.g. B. '/ woo, the Has sensitivity of this channel. The Impulsslärkc over the Rundumoplik 2.11 with cell 6 and amplifier 7 sends in the cell 13 and the amplifier 14 via the evaluation device 8 at low energy, while at high energy the cell 16 and the amplifier 17 are switched for evaluation.
Um außer zwischen Richlungsbereichen auch noch zwischen Strahlungsalien und Wellenlängen — z. B. Neodym- oder COi-Laser — und Impulsstärken unterscheiden zu können, muß einmal die Auswerteelektronik so ausgelegt sein, daß sie hinsichtlich der Dauer der einzelnen Impulse unterscheiden kann und zum anderen müssen die Linsenoptik 11, die am Ende 5' bis 5*" der Lichtleiter 41 bis4x" vorgesehene Sammellinse 12 sowie die Sektoroptiken 31 bis 3X" als Spiegeloptiken, die Lichtleiter 41 bis 4XI1 als Hohllichtleiter und die lichtempfindlichen Zellen 6,13 und 16 als Fotoempfänger ausgebildet sein. Bei der Verwendung von Hohllichlleitem werden zur Erfassung des Spektralbereiches von etwa 0,25 bis ΙΟμιτι pro Kanal z. B. drei Poloempfänger mit Spcktralteiler und Verstärker verwendet. Durch Oberlappen des Bildwinkels der Sektoroptiken 31 bis 3X" kann beim Vergleich der Signalform des Rundumkanals mit dem Sektorkanal über einen Rechner die horizonta-Ie Anzeigegenauigkeit auf 1 ° verbessert werden.In addition to between directional areas also between radiation and wavelengths - z. B. Neodymium or COi laser - and pulse strengths, the evaluation electronics must be designed so that they can differentiate in terms of the duration of the individual pulses and on the other hand must the lens 11, which at the end of 5 'to 5 * " the light guide 4 1 to 4 x "provided converging lens 12 and the sector optics 3 1 to 3 X " as mirror optics, the light guides 4 1 to 4 XI1 as hollow light guides and the light-sensitive cells 6, 13 and 16 as photo receivers up ΙΟμιτι per channel for example for detecting the spectral range of about 0.25. three Polo receiver with Spcktralteiler and amplifiers used. Due to the upper lobe of the angle of the sector lenses 3 1 to 3 X 'may the comparison of the waveform of the all-round channel with the sector channel via a Calculator the horizontal display accuracy can be improved to 1 °.
Selbstverständlich sind die Sekloropliken und Lichtleiter sowie deren Länge nicht auf die angegebenen Zahlenwerle beschränkt, sondern sie lassen sich — dem jeweiligen Verwendungszweck entsprechend — variie- to ren, je nach der gewünschten Empfindlichkeit des Gerätes. Of course, the Sekloropliken and light guides as well as their length are not limited to the specified Numbers are limited, but they can be varied - according to the respective purpose depending on the desired sensitivity of the device.
Bei einem in der Zeichnung nicht festgehaltenen Ausführungsbeispiel ist anstelle der vielen vergleichsweise kurzen Lichtleiter auch die Verwendung von nur einem einzigen, dafür aber entsprechend langen Lichtleiter mit einer mit der Anzahl der Sektoroptiken übereinstimmenden Anzahl von Einspeisungsstellen vorgesehen.In an embodiment not shown in the drawing instead of the many comparatively short light guides, only one is used single, but correspondingly long light guide with one that corresponds to the number of sector optics Number of feed points provided.
