Definitions

  • the invention relates to a device for checking and readjusting the alignment of the line of sight of a thermal imaging device to the direction of the muzzle tangent of the cannon of an armored combat vehicle, the thermal imaging device being arranged in a viewing head of the vehicle, which has an adjustment channel in the visible range of the electromagnetic spectrum.
  • the checking and readjustment of the direction of the line of sight to the direction of the mouth tangent is referred to in the relevant parlance as "field adjustment".
  • the invention is based on the object of specifying a device for the field adjustment of a thermal imaging device in a combat vehicle, which enables the gunner to check the adjustment of the thermal imaging device to the weapon before use and / or during use and to readjust if necessary without that he has to get out of the vehicle.
  • a reference mirror is arranged at the pipe mouth of the on-board cannon, that a device for transmitting and receiving a target beam is provided in the viewing head of the thermal imaging device, that potentiometers for basic adjustment of the field adjustment system are provided on the viewing head, that for the field adjustment required electronics is integrated in the tracking electronics of the thermal imaging device and that an operating and display device for field adjustment is provided in front of the gunner position.
  • the advantages achieved by the invention are in particular that the direction of the line of sight of a thermal imaging device to the direction of the muzzle tangent of an on-board cannon of armored vehicles can be checked and readjusted without the crew having to leave the vehicle.
  • 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.
  • 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.
  • the operating and display device for field adjustment of the thermal imaging device is designated by (4) in the illustration in FIG. 1.
  • the tracking electronics with the portion of the field adjustment of the thermal imaging device are contained in the structural unit identified by the reference symbol (3).
  • 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.
  • the setting potentiometer for the height bears the mark (13), that for the side the mark (14).
  • a cover plate (15) is provided for protection and against unintentional adjustment of the control potentiometer. (12, 12 Drucker) indicates an on-off switch for field adjustment of the thermal imager.
  • the cables additionally required for field adjustment are not shown in the illustrations in FIGS. 1 and 2.
  • 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.
  • the point adjustment of the thermal imaging device is carried out by adjusting the target.
  • the weapon 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.
  • 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".
  • the weapon 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".
  • a mirror (16) is automatically adjusted so that the line of sight (30) migrates by the angle ⁇ .
  • the basic adjustment of the field adjustment system is corrected by the angle ⁇ via the potentiometer (8 ⁇ ).
