Definitions

  • the present invention relates to a device and a method for tracer stream simulation at a biocular sight.
  • the invention is particularly intended to be used for tracer stream simulation at a biocular sight in a weapon system, such as for instance a tank.
  • a laser unit which is mounted to the barrel and emits a laser beam in the pointing direction of the barrel when firing takes place, is often used in simulated firing.
  • this type of simulated firing it is often desirable to present for the marksman a simulated tracer stream representing the calculated trajectory of a simulated projectile fired from the weapon.
  • an image comprising a simulated tracer stream can without any major problems be superposed on the normal image conveyed by the sight.
  • a unit reflecting the tracer stream image into the sight via a beam splitter arranged in front of or behind the sight is normally used in this connection.
  • the image comprising the tracer stream has been projected into both of the eyes of the person looking into the sight via two separate ray paths, i.e. via a first ray path for the right eye and a second ray path for the left eye.
  • the unit comprising the beam splitter and the other components required for the tracer stream simulation will become unwieldy large when the unit is to be adapted for tracer stream simulation at a biocular sight with an exit aperture of said size.
  • biocular sight refers to a sight which it is intended to look into with both eyes simultaneously via one and the same exit aperture. Consequently, a biocular sight comprises optical elements being com- mon for both eyes.
  • the object of the present invention is to achieve a device for tracer stream simulation at a biocular sight, by means of which device an image comprising simulated tracer stream in a simple and efficient manner can be superposed on the sight image conveyed by the sight.
  • said object is achieved by means of a device having the features defined in claim 1 .
  • the inventional solution implies that the simulated tracer stream is only projected into one of the eyes of a person looking into the sight provided with the device.
  • the solution according to the invention constitutes a new approach going in the opposite direction to the prevailing development within this technical field.
  • the inventional so- lution a number of advantages are obtained. Inter alia, the risk that a person looking into the sight will see a double image of the simulated tracer stream is completely eliminated.
  • the diameter of the exit aperture will be about the half when projecting into one ,eye as compared with projecting into both eyes. This implies that the linear dimensions of the tracer stream generator can be reduced to the half and the volume is thereby reduced to an eighth.
  • the inventional device can for instance be made small enough for making it possible to mount the device at a biocular sight in a combat vehicle, such as a tank, where the space normally is very limited.
  • the invention also relates to the use of the inventional device for tracer stream simulation at a biocular sight in a weapon system, such as a tank, according to claim 8 and a method for tracer stream simulation according to claim 9.

  • the device 1 comprises means for generation in an image plane 2 of an image comprising a simulated tracer stream from a projectile, this image plane 2 being located at the side of an aperture 3 (see fig 4) included in the device, so that the image plane 2 does not lie directly in the field of view 4a, 4b of a person looking through the device via said aperture 3.
  • Said means preferably consists of a cathode ray tube, schematically indicated at 5 in fig 1 , in which case the image plane of the cathode ray tube consequently constitutes the image plane 2.
  • Said means can for in- stance also consist of a LCD-display of reflecting or transmitting type or of a light emitting diode array.
  • the device further comprises a beam splitter 6 arranged to project the tracer stream image generated in the image plane 2 into one 10a of the eyes of a person looking through the device via said aperture 3.
  • An ocular 7 is arranged between the beam splitter 6 and the image plane 2.
  • the device 1 is intended to be placed in front of a biocular sight, schematically indicated at 8 in fig 1-3, so that a person looking into the sight 8 in one 10a of his eyes (the right one in fig 2) will see an image generated in the image plane 9 of the sight with the image, comprising the simulated tracer stream, generated in the image plane 2 of the device superposed, and in his other eye 10b (the left one in fig 2) will see the image generated in the image plane 9 of the sight without any image comprising simulated tracer stream superposed.
  • fig 2 it is clearly illustrated how the tracer stream image generated in the image plane 2 of the device only is projected via the beam splitter 6 into one of the eyes of a person looking into the sight.
  • the beam splitter 6 has such an extension that it covers the fields of sight 4a, 4b for both eyes 10a, 10b of a person looking into the sight 8.
  • the beam splitter 6 only is arranged to project the tracer stream image into one of the eyes, it is however sufficient that the beam splitter 6 has such an extension that it only covers the field of sight 4a for one of the eyes of a person looking into the sight 8.
  • the beam splitter 6 comprises a semi-transparent mirror 1 1 , which is arranged to reflect rays of light from the image generated in the image plane 2 of the device and thereby project this image into one 10a of the eyes of a person looking into the sight 8.
  • the semi-transparent mirror 1 1 is further arranged to allow rays of light from the image generated in the image plane 9 of the sight to pass through.
  • the beam splitter 6 comprises two pieces of glass 12, 13 with triangular cross-sectional shape, which are joined together by means of gluing so as to jointly form an element with rectangular cross-sectional shape.
  • a mirror coating 1 1 is arranged in the joint between the pieces of glass 12, 13.
  • the mirror coating 1 1 can either consist of a separate layer-shaped element or be integrated with one of the pieces of glass.
  • Other designs of the beam splitter 6 besides the one described above are of course also possible. The principle thing is that the beam splitter will function as a semi-transparent mirror in the above-indicated manner.
  • Fig 3 shows an inventional device 1 mounted in front of the exit aperture of a biocular sight 8, preferably a biocular sight in a tank.
  • the device 1 comprises a casing 14 enclosing the means 5 for generation of the tracer stream image, the ocular 7 and the beam splitter 6.
  • An aperture 3 is arranged at a front wall 15 of the casing, through which aperture a person looking into the sight is intended to direct his eyes.
  • This aperture 3 can with advantage be rectangular and can for instance have a size of about 35x80 mm. This shape and size of the aperture 3 is sufficient for allowing a person to look comfortably into the sight via the aperture 3 with both eyes.
  • the aperture 3 of the device has a smaller exten- sion than the exit aperture of the sight, which as previously mentioned normally has a diameter in the order of 80 mm, a part of the space directly in front of the exit aperture of the sight can be used for accommodating the components included in the device 1 , whereby the device 1 can be made more compact and space-saving.
  • a not shown ap- erture is arranged, which aperture has essentially the same shape and size as the aperture 3 at the front wall 15 of the casing and which is arranged coaxially with this aperture.
  • the device according to the embodiment shown in fig 3 further comprises a tube-shaped holding member 17, which is connected to the casing 14 and protrudes from the rear wall 16 of the casing.
  • the tube-shaped holding member 17 has an inner diameter which is somewhat larger than the outer diameter of the sight, at the front end of the sight, so that the device 1 can be attached to the sight 8 by applying the holding member 17 so that it en- closes the front part of the sight 8.
  • a quick-action fastener 18, which is attached to the holding member 17, is adapted to secure the device 1 to the sight 8.
  • the means 5 for generation of simulated tracer stream included in the device 1 is suitably supplied with electric current from a separate current source placed at a distance from the device, in which case the device 1 is provided with a not shown connection for connecting up of current from said current source to said means 5.
  • the means 5 for generation of simulated tracer stream is via a not shown connection connectable to a computer unit, which preferably is arranged in a separate unit placed at a distance from the inventional device. Said means 5 can of course also be connected to the computer unit via a wireless connection.
  • This computer unit is adapted to control the tracer stream generation in dependence on given parameters and the aiming of the marksman of a weapon unit associated with the sight so that the simulated tracer light represents the tracer light from a simu- lated projectile fired from said weapon unit.
  • the device according to the invention is particularly intended to be used for tracer stream simulation at a biocular sight in a weapon system, such as a tank, in which case the simulated tracer stream is intended to represent the tracer stream from a simulated projectile fired by means of a weapon unit of the weapon system.

Abstract

L'invention porte sur un dispositif de simulation de sillage de traceuse au niveau d'un viseur binoculaire, ce dispositif comprenant une ouverture (3) qui, lorsqu'il est monté sur un viseur binoculaire, est destinée à être placée à l'avant de l'orifice de sortie du viseur de sorte qu'une personne regardant dans le viseur puisse voir, par cet orifice (3), une image acheminée par le viseur, et un générateur (5) générant dans un plan (2) une image comprenant un sillage simulé provenant d'un projectile, ce plan (2) d'image se situant du côté de l'ouverture (3) du dispositif. Ce dispositif comprend également un diviseur de faisceau (6) qui, lorsque le dispositif est monté sur le viseur binoculaire, est disposé de façon à projeter l'image comprenant le sillage simulé de traceuse dans l'oeil de la personne regardant dans le viseur de sorte qu'une image acheminée par le viseur et l'image comprenant le sillage simulé superposé se trouvent dans le champ de visée de cet oeil. Le dispositif est conçu de sorte que seule l'image acheminée par le viseur se trouve dans le champ de visée de l'autre oeil de la personne regardant dans le viseur. L'invention porte également sur l'utilisation de ce dispositif dans la simulation d'un sillage de traceuse au niveau d'un viseur binoculaire d'un système d'arme, et sur le procédé de simulation correspondant.
