Description
Die Erfindung betrifft eine Vorrichtung zur Schädigung von Objekten mittels gerichteter elektromagnetischer Strahlung. Solche Strahlung wird zur Bekämpfung von Objekten eingesetzt, die sich in einem gewissen Abstand von einer Schädigungsstrahlungsquelle befinden, wobei solche Objekte üblicherweise (Ausrüstungs-)Gegenstände, Munition und/oder Systeme sind, die etwa einem Gegner zugeordnet werden können oder aber die zu Trainingszwecken platziert worden sind. Diese Objekte müssen nicht statisch sein, sondern können sich auch bewegen. Gemeint sind hierbei damit explizit auch fliegende Objekte (UAVs, Munition,...), die sich auf einer bestimmten Trajektorie bewegen.The invention relates to a device for damaging objects by means of directed electromagnetic radiation. Such radiation is used to combat objects that are at a certain distance from a source of harmful radiation, such objects usually being (equipment) objects, ammunition and / or systems that can be assigned to an opponent or that are placed for training purposes have been. These objects do not have to be static, they can also move. This also explicitly means flying objects (UAVs, ammunition, ...) that move on a certain trajectory.
An derartigen Vorrichtungen kommen optische Systeme, welche von wenigstens einem zu schädigenden Objekt abgegebene Strahlung erfassen und verarbeiten, zum Einsatz, um die zu bekämpfenden Objekte als Ziele zunächst überhaupt erkennen, gegebenenfalls zu klassifizieren, nach Erstellung einer Abwehrstrategie das potentielle Zielobjekt sogenannt zu "tracken" (nachzuverfolgen) und die Schädigungsstrahlung als Abwehrstrahlung auf das Objekt bzw. einen bestimmten Punkt des Objekts ("aim point") auszurichten. Solche Vorrichtungen zur Schädigung von Objekten mittels gerichteter elektromagnetischer Strahlung kennt man beispielsweise aus der
Als optisches System kommen dabei sowohl abbildende optische Systeme wie Kameras, als auch nicht-abbildende Systeme wie zum Beispiel Positionssensoren in Frage. Diese optischen Systeme sind üblicherweise empfindlich bei einer oder mehreren bestimmten Frequenzen oder Frequenzbereichen des elektromagnetischen Spektrums. Üblicherweise sind diese Frequenzen im Bereich des sichtbaren Spektrums bzw. im Infrarot-Spektrum.Both imaging optical systems such as cameras and non-imaging systems such as position sensors can be used as the optical system. These optical systems are usually sensitive to one or more specific frequencies or frequency ranges of the electromagnetic Spectrum. Usually these frequencies are in the range of the visible spectrum or in the infrared spectrum.
Zur Bekämpfung eines als Ziel identifizierten Objekts eignet sich insbesondere Hochenergie-Laserstrahlung, weswegen wenigstens eine Schädigungsstrahlungsquelle vorgesehen ist, die das wenigstens eine Objekt mit einer elektromagnetischen Abwehrstrahlung beaufschlagt, was ein sehr genaues Tracking des Zielobjekts notwendig macht. Dabei muss für die hierbei benötigte Präzision das Ziel in der Regel aktiv beleuchtet werden. Hierfür ist regelmäßig eine Beleuchtungseinrichtung vorzusehen, welche das wenigstens eine zu schädigende Objekt durch zumindest eine Beleuchtungsstrahlungsquelle mit einer Beleuchtungsstrahlung zumindest zeitweise aktiv beleuchtet.High-energy laser radiation is particularly suitable for combating an object identified as a target, which is why at least one damaging radiation source is provided which applies electromagnetic defense radiation to the at least one object, which makes very precise tracking of the target object necessary. In order to achieve the required precision, the target usually has to be actively illuminated. For this purpose, a lighting device must regularly be provided which actively illuminates the at least one object to be damaged by at least one illuminating radiation source with illuminating radiation, at least at times.
Entsprechend sind die genannten Schädigungsvorrichtungen mit ihren Laserstrahlungsquellen mit Beleuchtungssystemen versehen, bei denen die separate Installation von Tracking -und/oder Richtsystemen mit Aufwand verbunden ist und deren Trackingwerte bzw. ermittelten Trajektorien von Zielobjekten zu deren Bekämpfung in das Koordinatensystem der Schädigungsstrahlungsquelle zu überführen sind.Correspondingly, the aforementioned damage devices with their laser radiation sources are provided with lighting systems in which the separate installation of tracking and / or directional systems is costly and their tracking values or determined trajectories of target objects must be transferred to the coordinate system of the damage radiation source in order to combat them.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Schädigung eines Objekts mittels Abwehrstrahlung mit einem System zur aktiven Beleuchtung anzugeben, die hinsichtlich Installation und Handhabbarkeit mit einem geringeren Aufwand betreibbar ist und ein präzises Tracking der jeweiligen Zielobjekte gestattet.It is therefore the object of the present invention to specify a device for damaging an object by means of defensive radiation with a system for active lighting, which can be operated with less effort in terms of installation and handling and which allows precise tracking of the respective target objects.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Die Lösung besteht demnach insbesondere darin, bei einer Vorrichtung der eingangs genannten Art, die Beleuchtungseinrichtung an der Vorrichtung derart zu integrieren, dass die Beleuchtungsstrahlung und die Schädigungsstrahlung eine gemeinsame Austrittsapertur aufweisen bzw. diese nutzen und die Schädigungsstrahlung und die Beleuchtungsstrahlung einen im Wesentlichen kollinearen Strahlengang aufweisen. Hierdurch werden weitergehende Probleme vermieden, wie zum Beispiel das gleichzeitige Nachführen der Strahlen auf dem Zielobjekt mit unterschiedlichen Richtsystemen, außerdem können bei den beiden Systemen unterschiedliche Sichtachsen vermieden werden, wodurch keine Parallaxe kompensiert werden muss.According to the invention, this object is achieved by the features of claim 1. The solution therefore consists in particular in a device of the initially mentioned type of integrating the lighting device on the device in such a way that the lighting radiation and the damaging radiation have or use a common exit aperture and the damaging radiation and the lighting radiation have an essentially collinear beam path. This avoids further problems, such as, for example, the simultaneous tracking of the beams on the target object with different directional systems; in addition, different visual axes can be avoided in the two systems, so that no parallax has to be compensated.
Mit der erfindungsgemäßen Vorrichtung hat man eine gemeinsame Apertur für Schädigungsstrahlung und Beleuchtungssystem zur Verfügung und kann die Strahlungsquellen für die aktive Beleuchtung und die Schädigungsstrahlung in geeigneter Weise koppeln. Hierdurch werden separate Tracking-/Richtsysteme überflüssig, das optische System und eine Strahlrichteinheit (etwa in Form eines sogenannten beam director) wird kompakter, schließlich vereinfacht sich auch die Anbindung alternativer Beleuchtungslaserquellen.With the device according to the invention, a common aperture is available for the damaging radiation and the lighting system, and the radiation sources for the active lighting and the damaging radiation can be coupled in a suitable manner. As a result, separate tracking / straightening systems become superfluous, the optical system and a beam straightening unit (for example in the form of a so-called beam director) become more compact, and finally the connection of alternative illumination laser sources is also simplified.
Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.The subclaims contain further advantageous features.
Die Kollinearität der Schädigungsstrahlung und der Strahlung der aktiven Beleuchtung kann durch eine geeignete Kopplung erreicht werden, wofür zweckmäßigerweise bei einer weiteren Ausführung der erfindungsgemäßen Vorrichtung ein erstes Kopplungsmittel vorgesehen ist.The collinearity of the damaging radiation and the radiation of the active lighting can be achieved by a suitable coupling, for which purpose a first coupling means is expediently provided in a further embodiment of the device according to the invention.
In vorteilhaften Weiterbildungen kann ein solches Kopplungsmittel beispielsweise durch wenigstens einen Stahlkombinierer (beam combiner) gebildet sein, dieser wiederum kann beispielsweise mittels Strahlteilern oder Interferenzfilter in Art von dichroitischen Spiegeln gebildet sein.In advantageous developments, such a coupling means can be formed, for example, by at least one steel combiner (beam combiner) in turn, for example, it can be formed by means of beam splitters or interference filters in the manner of dichroic mirrors.
Die Strahlformung bei der erfindungsgemäßen Vorrichtung kann in geeigneter Weise mit hohen Transmissions- und Wirkungsgraden auch mit einem diffraktiven optischen Element (DOE) als Kopplungsmittel realisiert werden, bei denen eine Beugung an einem optischen Gitter stattfindet.The beam shaping in the device according to the invention can be implemented in a suitable manner with high degrees of transmission and efficiency also with a diffractive optical element (DOE) as coupling means, in which diffraction takes place at an optical grating.
Ein Kopplungsmittel ganz eigener Art bildet hierbei die Nutzung unterschiedlicher Anteile der Gesamtapertur durch die Schädigungsstrahlung und die Beleuchtungsstrahlung, wobei etwa denkbar ist, dass eine geometrisch gesehen einen ringförmigen Anteil bildet, während die andere einen zentralen Anteil einnimmt oder nebeneinander angeordnete Anteile der Gesamtapertur separat genutzt werden.A coupling means of its own is the use of different portions of the overall aperture by the damaging radiation and the illuminating radiation, it being conceivable that one forms a ring-shaped portion from a geometrical point of view, while the other occupies a central portion or portions of the overall aperture arranged next to one another are used separately .
Schließlich sind auch andere Kopplungsmittel und/oder Kombinationen der genannten Kopplungen denkbar.Finally, other coupling means and / or combinations of the couplings mentioned are also conceivable.
Eine andere, die Handhabung insgesamt noch weitere vereinfachende Weiterbildung der Vorrichtung kann darin bestehen, dass zweckmäßigerweise ein optisches System mit einem oder einer Mehrzahl von Detektoren die gemeinsame Apertur von Schädigungsstrahlung und Beleuchtungsstrahlung ebenfalls nutzt.Another further development of the device that simplifies handling overall can consist in the fact that an optical system with one or a plurality of detectors expediently likewise uses the common aperture of damaging radiation and illuminating radiation.
Hierdurch wird auch das optische Empfangssystem kollinear in das Gesamtsystem eingebunden, mithin wird die gemeinsame Apertur wird nicht nur für Schädigungsstrahlung und aktive Beleuchtung mit Beleuchtungsstrahlungsquellen verwendet, sondern auch für das optische System mit Detektoren.As a result, the optical receiving system is also integrated into the overall system in a collinear manner, so the common aperture is not only used for damage radiation and active illumination with illumination radiation sources, but also for the optical system with detectors.
Da die Kollinearität auch hier durch eine geeignete Kopplung erreicht werden kann,. ist bei einer anderen Ausführung ein zweites Kopplungsmittel vorgesehen, das diese zur Verfügung stellt. Dabei können bei dem zweiten Kopplungsmittel die gleichen Arten von Kopplungsmitteln wie bei dem ersten Kopplungsmittel zum Einsatz kommen (beam combiner, Strahlteiler, Interferenzfilter, DOE), gegebenenfalls sind erstes und zweites Kopplungsmittel auch identischSince the collinearity can also be achieved here by a suitable coupling. a second coupling means is provided in another version, that makes this available. The same types of coupling means can be used in the second coupling means as in the first coupling means (beam combiner, beam splitter, interference filter, DOE); the first and second coupling means may also be identical
Bei der erfindungsgemäßen Vorrichtung, mit welcher sich die zu schädigenden Objekte anhand Ihrer abgegebenen Strahlung erkennen, klassifizieren und verfolgen ("tracken") lassen , ist das optische System als abbildendes optisches System, wie Kameras, oder als nicht-abbildendes optisches System, wie zum Beispiel Positionssensoren , ausgebildet. Das optische System umfasst wenigstens einen Detektor, insbesondere eine Mehrzahl von Detektoren, welche empfindlich bei einer oder mehreren bestimmten Frequenzen oder Frequenzbereichen des elektromagnetischen Spektrums sind. Dies können etwa Frequenzen im Bereich des sichtbaren Spektrums bzw. des Infrarot-Spektrums sein.In the device according to the invention, with which the objects to be damaged can be recognized, classified and tracked based on the radiation they emit, the optical system is an imaging optical system, such as cameras, or a non-imaging optical system, such as for Example position sensors, trained. The optical system comprises at least one detector, in particular a plurality of detectors which are sensitive to one or more specific frequencies or frequency ranges of the electromagnetic spectrum. These can be frequencies in the range of the visible spectrum or the infrared spectrum.
Für die Erfassung insbesondere bewegter zu schädigender Objekte ist bei der erfindungsgemäßen Vorrichtung die aktive Beleuchtung mit mehreren Beleuchtungsstrahlungsquellen versehen , deren Frequenzen oder Frequenzbereiche auf die Empfindlichkeiten von denFor the detection of particularly moving objects to be damaged, in the device according to the invention, the active lighting is provided with a plurality of illuminating radiation sources, the frequencies or frequency ranges of which are influenced by the sensitivities of the
Detektoren des optischen Systems abgestimmt sind, so dass zur Erlangung eines rauscharmen. genügend starken, verfolgbaren Signals keine gesonderten Abstimm- oder Einmessprozesse notwendig sind.Detectors of the optical system are tuned so that to obtain a low noise. sufficiently strong, traceable signal no separate adjustment or calibration processes are necessary.
Mit unterschiedlicher Zielrichtung können vorteilhafte Ausführungsformen der erfindungsgemäßen Vorrichtung Beleuchtungsstrahlungsquellen aufweisen, die durch eine beliebige Kombination von köhärenten und/oder oder inkohärenten, polarisierten und/oder unpolarisierten, Strahlungsquellen gebildet ist, die gepulst, in Impulsgruppen , moduliert oder kontinuierlich (Dauerstrich) betrieben werden.With different aims, advantageous embodiments of the device according to the invention can have illuminating radiation sources that are generated by any combination of coherent and / or incoherent, polarized and / or unpolarized, radiation sources is formed, which are pulsed, operated in pulse groups, modulated or continuously (continuous wave).
Insbesondere können hierbei für die Beleuchtungsstrahlung Strahlungsquellen mit unterschiedlichen Eigenschaften und Frequenzen in Überlagerung vorgesehen sein.In particular, radiation sources with different properties and frequencies can be superimposed for the illumination radiation.
Ein hohes Maß an Flexibilität im Einsatz der erfindungsgemäßen Vorrichtung wird mit Weiterbildungen erreicht, bei denen Parameter der einzelnen Strahlungsquellen frei einstellbar und/oder regelbar sein, wobei insbesondere die Leistung, Polarisation, Strahldurchmesser, Impulsdauer und/oder Impulsfrequenz einstellbar oder regelbar sind.A high degree of flexibility in the use of the device according to the invention is achieved with developments in which the parameters of the individual radiation sources can be freely set and / or regulated, with in particular the power, polarization, beam diameter, pulse duration and / or pulse frequency being adjustable or controllable.
Erfindungsgemäß entsprechen sich die Frequenzen oder Frequenzbereiche der Strahlungsquellen von aktiver Beleuchtung und Schädigungsstrahlung und diese jeweiligen Strahlungsquellen werden während der Schädigung des Objekts im Zeitmultiplexing-Betrieb betrieben.According to the invention, the frequencies or frequency ranges of the radiation sources of active lighting and damaging radiation correspond, and these respective radiation sources are operated in time-division multiplexing mode while the object is being damaged.
Zu bestimmten Zeiten ist dann jeweils nur jeweils eine Strahlungsquelle aktiv, was die Leistungsanforderungen insgesamt verringert.At certain times, only one radiation source is active at a time, which reduces the overall performance requirements.
