In diesem Ausblickkopf ist eine optische Sender- und Empfängereinheit integriert, die in der deutschen Patentanmeldung P 36 22 769.2 beschrieben ist. Hierbei wird der Senderstrahl über einen dem Wärmebildkanal zugeordneten visuellen Justierkanal, der fest dem (in der Darstellung nicht sichtbaren) Ausblickspiegel des Wärmebildgerätes zugeordnet ist, zum Referenzspiegel (1) geschickt, dort reflektiert und über den gleichen Weg zurück zum Empfänger geschickt. Die Potentiometer für die Grundjustierung der Feldjustieranlage sind in der Darstellung der Figur 1 mit (8) bezeichnet. Das Bedien- und Anzeigegerät für die Feldjustierung des Wärmebildgerätes ist in der Darstellung der Figur 1 mit (4) bezeichnet. In der durch das Bezugszeichen (3) gekennzeichneten Baueinheit ist die Nachführ-Elektronik mit dem Anteil der Feldjustierung des Wärmebildgerätes enthalten.In the view of an armored combat vehicle shown in FIG. 1, the reference symbol (1) denotes a reference mirror attached to the pipe mouth (9) of the on-board cannon (5). The gunner's line of sight is marked (6), the muzzle tangent of the gun is marked (7). The lookout head for the thermal imager is labeled (2). An optical transmitter and receiver unit, which is described in German patent application P 36 22 769.2, is integrated in this view head. Here, the transmitter beam is sent to the reference mirror (1) via a visual adjustment channel assigned to the thermal image channel, which is fixedly assigned to the (not visible in the illustration) view mirror of the thermal imaging device, where it is reflected and sent back to the recipient via the same route. The potentiometers for the basic adjustment of the field adjustment system are denoted by (8) in the illustration in FIG. 1.

In der Darstellung des Bedien- und Anzeigegerätes für die Feldjustierung zum Wärmebildgerät der Figur 2 sind mit den Bezugszeichen (10) und (11) die Optimierungsanzeigedioden gekennzeichnet, und zwar mit (10) die Optimierungsanzeigedioden der Feldjustierung in Höhe und mit dem Kennzeichnen (11) die Optimierungsanzeigedioden der Feldjustierung für die Seite. Das Stellpotentiometer für die Höhe trägt das Kennzeichen (13), das für die Seite das Kennzeichen (14). Eine Abdeckplatte (15) ist zum Schutz und gegen umbeabsichtigtes Verstellen der Stellpotentiometer vorgesehen. Mit (12,12ʹ) ist ein Ein- Aus-Schalter für die Feldjustierung däs Wärmebildgerätes gekennzeichnet. Die für die Feldjustierung zusätzlich benötigten Kabel sind in den Darstellungen der Figur 1 und 2 nicht eingezeichnet.In the representation of the operating and display device for the field adjustment for the thermal imaging device of FIG. 2, the optimization display diodes are identified by reference numerals (10) and (11), namely (10) the optimization display diodes of the field adjustment in height and by the identification (11) the optimization display diodes of the field adjustment for the side.

Voraussetzung für die einwandfreie Funktion der Feldjustierung ist die Grundjustierung des Wärmebildgerätes und die Grundjustierung der Feldjustieranlage. Die Grundjustierung des Wärmebildgerätes wird über den visuellen Justierkanal durchgeführt. Der Wärmebildgerät-Ausblickkopf wird so justiert, daß der Lotablauf und Gleichlauf und die Paralleljustierung der Anlage innerhalb der geforderten Toleranzen liegen. Nach der Grundjustierung des Ausblickkopfes wird die Punktjustierung des Wärmebildgerätes durch Verstellen der Zielmarke durchgeführt.The basic adjustment of the thermal imaging device and the basic adjustment of the field adjustment system are prerequisites for the proper functioning of the field adjustment. The basic adjustment of the thermal imaging device is carried out via the visual adjustment channel. The thermal imaging device outlook head is adjusted so that the solder flow and synchronism and the parallel adjustment of the system are within the required tolerances. After the basic adjustment of the outlook head, the point adjustment of the thermal imaging device is carried out by adjusting the target.
Zur Grundjustierung der Feldjustierung muß die Waffe in eine definierte Elevationsstellung gebracht werden und über den Ein- Aus-Schalter am Bedien- und Anzeigegerät der Feldjustierung in der Stellung "ein" wird die Feldjustierung aktiviert. Wie beim Kampfvisier läuft dann die Spiegelachse in eine für die Feldjustierung festgelegte Position ein, unabhängig von der Feuerleitanlage. Über die Potentiometer (8) wird der Ausblickspiegel so verstellt, daß der Sender der Feldjustieranlage auf den Referenzspiegel (1) und der reflektierte Strahl im Empfänger auf einen in der Zeichnung nicht sichtbaren Quadrantendetektor trifft. Die Optimierungsanzeigedioden (10) und (11) lassen erkennen, in welchem Sektor der Empfängerstrahl auftrifft. Die Potentiometer (8) werden solange verstellt, bis die mittlere Diode anzeigt. Damit ist die Grundjustierung der Feldjustierung abgeschlossen. Der Schalter (12) am Bediengerät Feldjustierung wird wieder auf "aus" geschaltet.For basic adjustment of the field adjustment, the weapon must be brought into a defined elevation position and in via the on-off switch on the operating and display device of the field adjustment the "on" position activates the field adjustment. As with the combat visor, the mirror axis then runs into a position defined for field adjustment, regardless of the fire control system. The view mirror is adjusted via the potentiometer (8) so that the transmitter of the field adjustment system hits the reference mirror (1) and the reflected beam in the receiver hits a quadrant detector that is not visible in the drawing. The optimization display diodes (10) and (11) show in which sector the receiver beam is hitting. The potentiometers (8) are adjusted until the middle diode indicates. This completes the basic adjustment of the field adjustment. The switch (12) on the field adjustment control unit is switched back to "off".
Zur Überprüfung der Feldjustierung des Wärmebildgerätes muß die Waffe in die vorgeschriebene Position gebracht werden. Am Bediengerät der Feldjustierung wird der Schalter (12) auf "ein" geschaltet. Die eventuelle Ablage der Feldjustierung ist an den Optimierungsdioden (10), (11) zu erkennen und kann über die Potentiometer (13), (14) korrigiert werden. Anschließend wird am Bediengerät der Feldjustierung der Schalter (12) wieder auf "aus" geschaltet.To check the field adjustment of the thermal imaging device, the weapon must be brought into the prescribed position. The switch (12) on the operator panel for field adjustment is switched to "on". The possible storage of the field adjustment can be recognized by the optimization diodes (10), (11) and can be corrected using the potentiometers (13), (14). The switch (12) on the field adjustment control unit is then switched back to "off".
Entsprechend dem in Figur 3 dargestellten Justierschema wird nach mechanischer Vorjustierung der Visierlinie (30) über das Potentiometer (13) am Bediengerät für Feldjustierung die Paralleljustierung zur Mündungstangente (7) hergestellt.According to the adjustment diagram shown in FIG. 3, after mechanical pre-adjustment of the line of sight (30) via the potentiometer (13) on the operating device for field adjustment, the parallel adjustment to the mouth tangent (7) is made.
Nach dem Einschalten der Feldjustieranlage mittels Schalter (12) der über den Schildzapfenresolver (17) mit dem Resolver Ausblickkopf (18) verbunden ist, wird ein Spiegel (16) automatisch so verstellt, daß die Visierlinie (30) um den Winkel α auswandert. Über das Potentiometer (8ʹ) wird die Grundjustierung der Feldjustieranlage um den Winkel Δα korrigiert.After switching on the field adjustment system by means of a switch (12) which is connected to the resolver view head (18) via the shield pin resolver (17), a mirror (16) is automatically adjusted so that the line of sight (30) migrates by the angle α. The basic adjustment of the field adjustment system is corrected by the angle Δα via the potentiometer (8ʹ).
Hat sich nach erfolgter Grundjustierung im Laufe der Zeit die Mündungstangente von (7) in (7a) verändert, erfolgt eine Korrektur über das Potentiometer (13) um den Winkel Δα. Für die Feldjustierung für die Seite wird anstelle des Potentiometers (13) das Potentiometer (14) betätigt.If the mouth tangent has changed from (7) to (7a) in the course of time after the basic adjustment has been carried out, one occurs Correction via the potentiometer (13) by the angle Δα. For the field adjustment for the side, the potentiometer (14) is actuated instead of the potentiometer (13).
