Description

Die Erfindung betrifft ein optische Zielhilfegerät nach dem Oberbegriff des Anspruchs 1. The invention relates to an optical aiming device according to the preamble of claim 1 .

Zielhilfegeräte dieser Art werden zum Beispiel zur Ausrichtung von Waffen verwendet. Sie erzeugen in der Regel einen gebündelten Lichtstrahl, der mit nur kleinem Abstand und im wesentlichen parallel zur Schussachse verläuft. Der auf dem Ziel sichtbare Lichtpunkt zeigt sodann im wesentlichen den Einschusspunkt an.Target assist devices of this type are, for example used to aim weapons. You generate usually a bundled beam of light with only small distance and essentially parallel to the shot axis runs. The point of light visible on the target then essentially shows the bullet point.

Für den Einsatz in grosser Dunkelheit sind solche Geräte nicht gut geeignet, da sie mit ihrem hellen Punkt den Beobachter blenden. In solchen Situationen muss deshalb zusätzlich eine Beleuchtung eingesetzt werden, die es entweder dem Auge oder eihem Nachtsichtgerät erlaubt, die groben Konturen des Zielbereichs zu erfassen. Dies ist jedoch relativ umständlich. For use in great darkness such devices are not well suited because they are bright Point blind the observer. In such situations therefore additional lighting is used, which either allows the eye or a night vision device, to grasp the rough contours of the target area. However, this is relatively cumbersome.

Aus der US-4,777,753-A ist ein optisches Zielhilfegerät bekannt, das eine Lichtquelle zur Emittierung eines Lichtstrahles im wesentlichen entlang einer Zielachse aufweist, wobei ein mittiger Teil des emittierten Lichstrahls ein gebündelter Zielstrahl ist, der aussen im wesentlichen von einem Zylnder begrenzt wird, während ein peripherer Teil des emittierten Lichtstrahls ein Beleuchtungsraum ist, der innen vom genannten Zylinder und aussen im wesentlichen von einem Kegel begrenzt wird. Man erhält damit auf einer quer zur Zielachse verlaufenden zu beleuchtenden Fläche einen nahezu punktförmigen stark beleuchteten Innenbereich und einen diesen umgebenden ausgedehnteren schwach beleuchteten zum Beispiel kreisringförmigen Aussenbereich.From US-4,777,753-A an optical aiming aid device is known which has a light source for emitting a light beam essentially along a target axis, a central part of the emitted light beam being a bundled target beam which is essentially delimited on the outside by a cylinder a peripheral part of the emitted light beam is an illumination space which is delimited on the inside by the said cylinder and on the outside essentially by a cone. In this way, an almost punctiform, strongly illuminated inner region and an extended, weakly illuminated, for example circular, outer region surrounding it are obtained on an area to be illuminated which runs transversely to the target axis.

Auch die BE-493 420-A offenbart eine optisches Zielhilfegerät mit einer Lichtquelle zur Emittierung eines Lichtstrahles in Form eines divergenten kegeligen Beleuchtungsfeldes im wesentlichen entlang einer Zielachse, und mit einer Ablenkoptik für den Lichtstrahl, durch welche aus dem Lichtstrahl ein im wesentlichen gebündelter Zielstrahl und ein divergenter Beleuchtungsraum gebildet werden. Die Ablenkoptik ist hierzu in zwei Bereiche unterteilt: ein erster, kreisringförmiger Bereich der Ablenkoptik lässt einen ersten Teil des Lichtstrahls unverändert durch, so das dieser erste Bereich ein Beleuchtungsfeld erzeugt, das die Form eines hohlen Rotationskörpers hat, der aussen von einem divergenten Kegel und innen von einem Zylinder begrenzt wird; ein zweiter Bereich der Ablenkoptik lenkt den auf ihn fallenden Teil des Lichtstrahl so ab, dass daraus ein gebündelter Zielstrahl entsteht, der aussen vom genannten Zylinder begrenzt wird. Auch hierbei erhält man auf einer quer zur Zielachse verlaufenden zu beleuchtenden Fläche einen nahezu punktförmigen stark beleuchteten Innenbereich und einen diesen umgebenden ausgedehnteren schwach beleuchteten, zum Beispiel kreisringförmigen Aussenbereich. BE-493 420-A also discloses an optical aiming aid device with a light source for emitting a light beam in the form of a divergent conical illumination field essentially along a target axis, and with deflecting optics for the light beam, through which a substantially bundled target beam and from the light beam a divergent lighting room can be formed. For this purpose, the deflecting optics are divided into two areas: a first, circular area of the deflecting optics allows a first part of the light beam to pass through unchanged, so that this first area creates an illumination field which has the shape of a hollow body of revolution that is outside of a divergent cone and inside is limited by a cylinder; a second area of the deflecting optics deflects the part of the light beam falling on it in such a way that a bundled target beam results therefrom, which is delimited on the outside by the cylinder mentioned. Here, too, an almost point-shaped, strongly illuminated inner region and an extended, weakly illuminated, for example circular, outer region surrounding it are obtained on an area to be illuminated which runs transversely to the target axis.

Die Aufgabe der Erfindung wird somit darin gesehen,

  • ein optisches Zielhilfegerät der eingangs genannten Art zu verbessern, das die Nachteile des Standes der Technik vermeidet.
The object of the invention is therefore seen in
  • to improve an optical aiming device of the type mentioned, which avoids the disadvantages of the prior art.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäss, ausgehend von genannten Stand der Technik nach BE-493 420-A

  • für das Zielhilfegerät durch die Merkmale des kennzeichnenden Teils des Anspruchs 1.
The solution of this object is achieved according to the invention, starting from art cited prior to BE-493 420-A
  • for the aiming aid device by the features of the characterizing part of claim 1 .

Vorteilhafte Weiterbildungen des erfindungsgemässen Zielhilfegerätes sind durch die Ansprüche 2 bis 10 definiert.Advantageous developments of the aiming device according to the invention are defined by claims 2 to 10 .

Das neue optische Zielhilfegerät umfasst eine Lichtquelle und eine Ablekenkoptik. Die Lichtquelle emittiert, im wesentlichen in Richtung einer Zielachse, einen gebündelten Lichtstrahl, der auf die Ablenkoptik fällt. Die letztere ist in zwei Bereiche unterteilt, wobei vom von der Lichtquelle emittierten Lichtstrahl ein Teil auf den ersten Bereich der Ablenkoptik und der Rest auf den zweiten Bereich der Ablenkoptik fällt. Der erste Bereich der Ablenkoptik lässt den auf ihn fallenden Teil des Lichtstrahles unverändert durch, so dass aus diesem ersten Bereich ein gebündelter Zielstrahl austritt. Der zweite Bereich der Ablenkoptik wirkt auf den auf ihn fallenden Teil des Lichtstrahls streuend, derart, dass dieser zweite Bereich der Ablenkoptik den auf ihn fallenden Teil des Lichtstrahles in ein divergentes Beleuchtungsfeld transformiert. Auf einer quer zur Zielachse verlaufenden zu beleuchtenden Fläche erhält man dadurch einen nahezu punkt- bzw. kreisförmigen stark beleuchteten Innenbereich und einen diesen umgebenden ausgedehnteren schwach beleuchteten zum Beispiel kreisringförmigen Aussenbereich. Derjenige Bereich der Ablenkoptik, der streuend wirkt und somit den divergenten Beleuchtungsraum erzeugt, kann aus dem Gang des Lichtstrahls entfernt bzw. abgeschattet werden. Dies hat zur Folge, dass aus der Ablenkoptik nur noch der gebündelte Zielstrahl austritt, während die Entstehung des divergenten Beleuchtungsraums verhindert wird. The new optical aiming aid includes a light source and deflecting optics. The light source emits a bundled light beam, essentially in the direction of a target axis, that falls on the deflection optics. The latter is divided into two areas, from by the light source emitted a portion of the first area of the deflecting optics and the The rest falls on the second area of the deflection optics. The first area of the deflection optics leaves the part of the light beam falling on it unchanged, so that from this first Area a bundled target beam emerges. The second area of the deflection optics acts on the Scattering part of the light beam falling on it, such that this second area of the deflection optics the part of the light beam falling on it into a divergent lighting field transformed. On a surface to be illuminated that runs perpendicular to the target axis one obtains thereby an almost point-shaped or circular, highly illuminated interior area and one this surrounding more extensive dimly lit, for example circular Outdoor area. The area of the deflection optics that has a scattering effect and thus the divergent Lighting room generated, can be removed or shaded from the path of the light beam become. As a result, only the bundled target beam remains from the deflection optics emerges, while the emergence of the divergent lighting space is prevented.

Als besonders einfach hat es sich hierbei erwiesen, einen Teil der unebenen Oberfläche der Optik mit einem Medium zu überdecken, das den gleichen Brechungsindex aufweist und die Unebenheit optisch ausgleicht. In einer bevorzugten Ausführung kann zum Beispiel zwischen einer Streulinse bzw. einer Streuplatte und einer planen Platte ein Tropfen eines optischen Leims eingebracht werden. Der Brechungsindex des Leims sollte dabei jenem der Streulinse bzw. Streuplatte entsprechen.It has proven to be particularly simple here part of the uneven surface of the optics to cover a medium that has the same refractive index exhibits and visually compensates for the unevenness. In a preferred embodiment can for example between a spreading lens or a spreading plate and plan one Plate a drop of an optical glue can be introduced. The refractive index of the glue should be that of the Lens or lens.

Als Lichtquelle wird vorzugsweise ein Laser verwendet, der Licht im sichtbaren oder infraroten Spektralbereich emittiert. Infrarot-Laser eignen sich insbesondere zur Kombination mit Nachtsichtgeräten.A laser is preferably used as the light source uses light in the visible or infrared spectral range emitted. Infrared lasers are particularly suitable for combination with night vision devices.

    • Zuerst soll die Wirkungsweise des Zielgeräts anhand von Figur 1 kurz erläutert werden. Das Zielgerät 1 besitzt eine Achse 2, die zum Beispiel parallel zur Schussachse einer Waffe justiert ist. Es erzeugt einerseits einen gebündelten Lichtstrahl 3, der sich entlang der Achse 2 ausbreitet. Gleichzeitig kann das Zielgerät jedoch auch einen divergenten Beleuchtungsraum bzw. Lichtkegel 4 erzeugen. Dieser Kegel hat einen Oeffnungswinkel von z. B. etwa 5 bis 30° und besitzt die Achse 2 als Symmetrieachse.First, the mode of operation of the target device are briefly explained with reference to Figure 1. The target device 1 has an axis 2 that is parallel to, for example Firing axis of a weapon is adjusted. On the one hand, it creates a bundled beam of light 3 that extends along the axis 2 spreads. At the same time, the target device however, also generate a divergent lighting space or light cone 4. This Cone has an opening angle of z. B. about 5 to 30 ° and has axis 2 as an axis of symmetry.

    Auf einem Zielobjekt 5 erzeugt der gebündelte Strahl 3 einen Lichtpunkt 6, der den Schnittpunkt der Achse 2 mit der Zielebene markiert. Sind die Waffe und das Zielgerät 1 richtig zueinander justiert, so entspricht der Lichtpunkt 6 im wesentlichen dem Einschusspunkt. Um den Lichtpunkt 6 herum bildet der Lichtkegel 4 einen erhellten Hof 7. Dies erlaubt es dem Beobachter im Dunkeln, nicht nur den Lichtpunkt 6 sondern auch dessen Umgebung zu erkennen, so dass die Lage des Lichtpunkts 6 auf dem Ziel und das Ziel bzw. dessen Umgebung identifiziert werden kann. Der Lichtkegel 4 wirkt also als Beleuchtungsraum, welcher Objekte, die in seinen Wirkbereich liegen, für den Beobachter sichtbar macht.The bundle is generated on a target object 5 Beam 3 a light point 6, which is the intersection of the Axis 2 marked with the target plane. Are the weapon and the target device 1 correctly adjusted to each other, so corresponds the light point 6 essentially the bullet point. The light cone 4 forms around the light point 6 an illuminated courtyard 7. This allows the observer in the Dark, not only the light point 6 but also its Detect surroundings, so that the position of the light point 6 identified on the target and the target or its environment can be. The light cone 4 thus acts as an illumination space, what objects that are in its scope lie to the observer.

    Die Figuren 2 - 4 zeigen Schnitte durch den Kopf eines erfindungsgemässen Zielgeräts 1. Das Gerät umfasst ein Gehäuse 8 mit vorderem Abschluss 9, einen Kopf mit Halter 10 und eine Lichtquelle 11. Ferner umfasst es noch eine Stromversorgung, Bedienungselemente und Justiervorrichtungen, deren Aufbau dem Fachmann bekannt ist und die deshalb in Figur 2 nicht dargestellt werden.Figures 2-4 show sections through the Head of a target device according to the invention 1. The device comprises a housing 8 with a front end 9, a head with holder 10 and a light source 11. Furthermore, it includes another power supply, controls and adjustment devices, the structure of which is known to the person skilled in the art and which are therefore not shown in Figure 2.

    Die Lichtquelle 11 ist in dieser Ausführung ein Halbleiterlaser, der Licht im infraroten oder sichtbaren Spektralbereich erzeugt. Die Lichtquelle 11 umfasst ferner eine (nicht gezeigte) Optik bekannter Ausführung, um das Licht der Laserdiode in einen möglichst parallelen Strahl 12 zu bündeln. Der Strahl 12 hat z. B. einen elliptischen Durchmesser von 3 x 5 mm.The light source 11 is in this version a semiconductor laser that emits light in the infrared or visible Spectral range generated. The light source 11 comprises furthermore a lens (not shown) of known design, to the light of the laser diode in a parallel as possible Bundle beam 12. The beam 12 has e.g. B. an elliptical Diameter of 3 x 5 mm.

    Der Kopf umfasst einen Halter 10, in dem drei Oeffnungen 13, 14 und 15 ausgespart sind. Der Halter 10 ist schwenkbar angeordnet, so dass jede der drei Oeffnungen in den Strahl 12 geschwenkt werden kann.The head comprises a holder 10 in which three Openings 13, 14 and 15 are left blank. The holder 10 is pivoted so that each of the three openings can be pivoted into the beam 12.

    In der in Figur 2 gezeigten Position tritt der Strahl 12 in die mittlere Oeffnung 15. In dieser Oeffnung sind keine optischen Elemente angeordnet, so dass der Strahl sie unverändert passiert. Somit erzeugt das Zielhilfegerät in dieser Stellung lediglich einen gebündelten Zielstrahl 3 aber keinen divergenten Beleuchtungsraum 4.In the position shown in Figure 2 occurs the beam 12 into the middle opening 15. In this No optical elements are arranged in the opening, so that the beam passes through it unchanged. Thus generated the aiming device in this position is only a bundled one Target beam 3 but no divergent lighting space 4th

    Durch den Drehpunkt 18b kann der Halter 10 gegenüber dem Abschluss 9 verschwenkt werden. Dabei bildet die Schraube 18b die Schwenkachse und die Schraube 18a läuft im Langloch 18c.The holder 10 be pivoted towards the conclusion 9. Thereby forms the screw 18b the pivot axis and the screw 18a runs in slot 18c.

    An der Innenseite des Halters 10 ist eine Aussparung 19 mit etwa nierenförmigem Umriss ausgefräst, in die das vordere Ende der Lichtquelle 11 eingreift. In den ausgeschwenkten Stellungen des Halters 10 steht die Lichtquelle 11 am Rand der Aussparung 19 an und bildet einen Anschlag.On the inside of the holder 10 is one Recess 19 milled out with an approximately kidney-shaped outline, into which the front end of the light source 11 engages. In the pivoted positions of the holder 10 is the Light source 11 on the edge of the recess 19 and forms a stop.

    In den seitlich ausgeschwenkten Stellungen des Halters 10 fällt der Strahl 12 der Lichtquelle 11 in eine der Oeffnungen 13 oder 14. In jeder dieser Oeffnungen ist je eine Ablenkoptik 16 bzw. 17 vorgesehen, deren Aufbau nun anhand der Figuren 5 und 6 beschrieben wird.In the swung-out positions of the holder 10, the beam 12 of the light source 11 falls into one of the openings 13 or 14. In each of these openings deflection optics 16 and 17 are provided, the Structure will now be described with reference to Figures 5 and 6.

    Die erste Ablenkoptik 16 nach Figur 5 umfasst eine plankonvexe Linse 20 und eine planparallele Platte 21. Die Platte 21 berührt die Linse 20 am höchsten Punkt ihrer konvexen Seite. Ferner ist an diesem Punkt ein Tropfen 22 eines optischen Leims angeordnet, der zwischen der Linse 20 und der Platte 21 einen Bereich mit Durchmesser d ausfüllt. Der Leim ist für das verwendete Licht transparent und weist im wesentlichen den gleichen Brechungsindex wie die Linse 20 auf. The first deflecting optics 16 according to FIG. 5 comprises a plano-convex lens 20 and a plane-parallel plate 21. The plate 21 touches the lens 20 at the highest point their convex side. Furthermore, is at this point Drop 22 of an optical glue arranged between an area with a diameter of the lens 20 and the plate 21 d fills out. The glue is for the light used transparent and has essentially the same refractive index like the lens 20.

    Wird nun der von der Lichtquelle ausgesandte Strahl 12 achsial durch die Optik nach Figur 5 geschickt, so wird er im Bereich des Leimtropfens 22 nicht abgelenkt und tritt im wesentlichen unverändert als gebündelter Zielstrahl 3 aus dem Zielhilfegerät, da hier die Linse 20 zusammen mit dem Leim optisch gesehen eine planparallele Platte bildet. Jener Teil des Strahls 12, der jedoch nicht durch den Leimtropfen tritt, wird von der konvexen Linsenoberfläche abgebeugt und stark fokussiert so dass er im Fernfeld als divergenten Beleuchtungsraum einen Lichtkegel 4 bildet.Now the one emitted by the light source Beam 12 passed axially through the optics according to FIG. 5, it is not deflected in the area of the glue drop 22 and occurs essentially unchanged as a bundle Target beam 3 from the aiming aid device, since here the lens 20 together with the glue optically a plane parallel Plate forms. That part of beam 12, however does not enter through the drop of glue, is from the convex Lens surface bent and strongly focused so that it forms a light cone 4 in the far field as a divergent lighting space.

    In einer bevorzugten Ausführung beträgt der Durchmesser d des Leimtropfens etwa 0.2 mm, die Brennweite der Linse liegt bei 18 mm, deren Durchmesser 8 mm. Der divergente Lichtkegel 4 hat in diesem Fall im Fernfeld eine Divergenz von etwa 10°.In a preferred embodiment, the Diameter drop of the glue drop about 0.2 mm, the focal length the lens is 18 mm, the diameter is 8 mm. The In this case, divergent light cone 4 has in the far field a divergence of about 10 °.

    Anstelle eines Leimtropfens kann gegebenenfalls auch ein Tropfen einer geeigneten Flüssigkeit verwendet werden.Instead of a drop of glue, if necessary a drop of a suitable liquid is also used become.

    Die zweite Ablenkoptik 17 nach Figur 6 umfasst einen Streukörper 25 und eine planparallele Platte 26. Der Streukörper 25 weist eine unebene Oberfläche 27 auf, welche eine Lichtstreuung bewirkt. Zwischen der Platte 26 und dem Streukörper 25 ist wiederum radial im Zentrum ein Tropfen 28 eines optischen Leims angeordnet, der den gleichen Brechungsindex wie die Streuplatte 25 aufweist.The second deflection optics 17 according to FIG. 6 comprises a diffuser 25 and a plane-parallel plate 26. The diffuser 25 has an uneven surface 27 which causes light scattering. Between the Plate 26 and the diffuser 25 is in turn radially in the Arranged in the center a drop 28 of an optical glue, which has the same refractive index as the scatter plate 25 having.

    Die Wirkungsweise der Ablenkoptik nach Figur 6 ist ähnlich wie jene der Optik nach Figur 5. Der von der Lichtquelle erzeugte Strahl 12 wird im Bereich des Leimtropfens 28 nicht abgelenkt und bildet den Zielstrahl 3. Der Teil des Strahls 12, der nicht durch den Leimtropfen 28 geht, wird an der Oberfläche 27 gestreut und verlässt die Ablenkoptik als divergenter Lichtkegel 4 mit einem Oeffnungswinkel von z. B. 30°.The operation of the deflection optics according to the figure 6 is similar to that of the optics according to FIG. 5 the light source 12 is generated in the range of Glue droplet 28 is not deflected and forms the target beam 3. The part of the beam 12 that is not through the glue drop 28 goes, is scattered on the surface 27 and leaves the deflection optics as a divergent cone of light 4 an opening angle of z. B. 30 °.

    Die Figuren 5 und 6 zeigen nur zwei der möglichen Ausführungen der Ablenkoptik. Andere Ausführungen sind denkbar. So kann zum Beispiel in der Ablenkungsoptik 16 auch eine bikonvexe Linse verwendet werden, wobei in diesem Falle beidseits der Linse eine planparallele Platte 21 und ein Leimtropfen 22 angeordnet werden muss.Figures 5 and 6 show only two of the possible Designs of the deflection optics. Other designs are conceivable. For example, in the distraction optics 16, a biconvex lens can also be used, wherein in in this case a plane-parallel plate on both sides of the lens 21 and a drop of glue 22 must be arranged.

    Die Ausführungen gemäss Figur 5 und 6 haben den Vorteil, das konventionelle optische Komponenten (Linse, Streuplatte) verwendet werden können.5 and 6 have the explanations the advantage of conventional optical components (Lens, diffusing plate) can be used.

    Der Leimtropfen 22 bzw. 28 und die Platte 21 bzw. 26 können entfallen, wenn die Linse 20 bzw. die Streuplatte 25 mit einem durchgehenden, achsialen Loch 35 versehen wird, wie dies in Figur 8 für die Streuplatte 25 dargestellt ist. In diesem Fall kann die Linse bzw. Streuplatte auch aus optisch minderwertigem Material wie z. B. Kunststoff sein, da an die optische Qualität des abgestreuten Lichts keine hohen Anforderungen gestellt werden.The glue drop 22 or 28 and the plate 21 or 26 can be omitted if the lens 20 or Scatter plate 25 with a continuous, axial hole 35 is provided, as shown in FIG. 8 for the diffusion plate 25 is shown. In this case the lens or Scattering plate also from optically inferior material like e.g. B. plastic, because of the optical quality of the scattered light made no high demands become.

    Es ist auch möglich, den höchsten Bereich 36 der konvexen Seite der Linse 20 plan abzuschleiffen, wie dies in Figur 7 gezeigt wird. Licht, das durch diesen Bereich tritt, wird nicht abgelenkt. Licht, das radial ausserhalb dieses Bereichs 36 austritt, wird zu einem Kegel abgelenkt und bildet den Beleuchtungsraum 4.It is also possible to have the highest area 36 grind the convex side of the lens 20 flat, like this is shown in Figure 7. Light shining through this area occurs, is not distracted. Light that radially outside this area 36 emerges, becomes a cone deflected and forms the lighting space 4.

    In den Ablenkoptiken gemäss den Figuren 5 - 8 wird jeweils der mittlere Teil des Strahls 12 nicht abgelenkt und der periphere Teil abgelenkt. Die Unterteilung zwischen dem nicht abgelenkten und dem abgelenkten Teil kann jedoch auch in anderer Weise geschehen, z. B. kann nur der mittlere Teil abgelenkt werden, indem ein Streuobjekt mit kleinem Durchmesser in den Strahl 12 eingebracht wird. Es können auch mehrere einzelne Streuobjekte kleiner Grösse über den Strahlquerschnitt verteilt werden, so dass mehrere Streuzentren entstehen - hierzu kann z. B. eine plane Streuplatte mit mehreren aufgerauhten Oberflächenbereichen verwendet werden.In the deflection optics according to FIGS. 5-8 the middle part of the beam 12 is not deflected and the peripheral part distracted. The subdivision between the undeflected and the distracted part can also be done in other ways, e.g. B. can only the middle part can be distracted by a scattering object introduced into the beam 12 with a small diameter becomes. You can also have several individual scatter objects small size can be distributed over the beam cross-section, so that several scattering centers arise - this can be done e.g. B. a flat scatter plate with several roughened Surface areas are used.

    Da in den seitlich ausgeschwenkten Stellungen des Halters 10 ein Teil der Lichtleistung zur Erzeugung des Beleuchtungskegels 4 benötigt wird, sollte in diesen Stellungen die vom Zielgerät ausgestrahlte totale Lichtleistung vorzugsweise höher als in der mittleren Stellung des Halters 10 sein. Hierzu kann z. B. ein in Figur 4 gestrichelt angedeuteter Stellungssensor 30 am Halter 10 vorgesehen sein, der die Leistung der Lichtquelle 11 erhöht, wenn deren Licht durch eine der Ablenkoptiken 16 oder 17 geschickt wird. Alternativ kann auch in der zentralen Oeffnung 15 des Halters 10 ein in Figur 4 gestrichelt gezeichnetes Abschwächfilter 31 vorgesehen sein, das die Lichtleistung des Strahls 12 abschwächt.Because in the positions swung out to the side of the holder 10 part of the light output for generation the lighting cone 4 is needed, should be in this Positions the total light output emitted by the target device preferably higher than in the middle position of the holder 10. For this, e.g. B. a dashed in Figure 4 indicated position sensor 30 provided on the holder 10 be, which increases the power of the light source 11, if their light through one of the deflecting optics 16 or 17 is sent. Alternatively, the central Opening 15 of the holder 10 is a dashed line in FIG Attenuation filter 31 may be provided, which Light output of the beam 12 weakens.

    Das beschriebene Zielgerät eignet sich für Einsätze aller Art. Das Gerät eignet sich insbesondere aber auch zur Kombination mit anderen optoelektronischen Hilfssystemen. So kann z.B. der von der Lichtquelle ausgesandte Strahl zeitlich moduliert und so mit Informatiions- bzw. Identifikationssignalen versehen werden, die dann gerichtet und gestreut übertragen werden.The target device described is suitable for All kinds of operations. The device is particularly suitable but also for combination with other optoelectronic Auxiliary systems. For example, the one emitted by the light source Beam modulated in time and thus with information or identification signals are provided that then directed and spread.
