  • the target in the area of the point of incidence of the laser radiation is locally strongly heated, which can lead to impairment of the object up to its complete destruction after only a short irradiation time.
  • the armor elements provided on these are able to develop a good protective effect against ballistic projectiles or explosive devices, for example, but are largely ineffective in the event of a laser attack.
  • This is mainly due to the fact that large amounts of energy are introduced via the laser beam into the armored element, which consists for example of armored steel, in a locally limited space, which can lead to destruction of the armored element after only a short exposure time.
  • the FR2 860 065 A1 relates to a system for protecting an object against a threat with a moveable shield, where the shield can be moved to protect the object at the point where the threat impacts the object.

  • the armoring element Due to the movable arrangement of the armoring element relative to the object, the armoring element can also be moved relative to the laser beam impinging on the object. This avoids an energy input that is locally limited to a single irradiation point. Depending on the movement of the armor element, the energy of the laser beam is coupled into the armor element not locally at just one irradiation point, but distributed over a larger area along the path of movement of the armor element. The risk of material failure as a result of the heat introduced by the laser radiation is significantly reduced.

It is therefore not possible for the attacker to anticipate the movements and to try to track the laser beam to the movements of the armored element in order in this way to target a specific point of the armored element under constant fire.
  • the protection covers at least the edges of the armor element. Covering the edges of the armoring element is sufficient in most cases, since the movement of an armoring element, in particular a plate-shaped one, can usually only be recognized at its edges.

It is therefore not necessary to use the armor element constantly in motion, but the armor element can be set in motion in a targeted manner in the event of a threat situation.
  • the movements of the armoring element are covered by a protective shield in such a way that they are not visible. In any case, it is not easily possible for an attacker to track the laser beam to the movements of the armor element in order to achieve a local energy input in this way.
  • FIG. 1 shows a perspective view of an object 10, which is designed to be protected against fire from laser weapons by laser armor 1.
  • the object 10 can be an immobile object, such as a building, a bunker, or a mobile target, such as a military vehicle and in particular a military land vehicle.
  • the laser armor 1 serves to protect against laser weapons, including according to the invention all beam weapons working by means of bundled radiation are to be understood.
  • the laser armor 1 consists of several tile-like armor elements 2 distributed over the object, which are arranged in front of a surface 11 of the object 10 to be protected. While the representation in 1 an embodiment of the protective arrangement 1 can be seen in which the armoring elements are only arranged on one side of the object 10, it goes without saying that the laser armoring 1 can also comprise armoring elements 2 on the other sides of the object 10, which primarily depends on from which side the threat is to be expected. In the case of a military vehicle, it makes sense to provide all sides of the vehicle as well as the vehicle roof with armoring elements 2 and not to armor the vehicle floor against laser bombardment, since the bombardment using laser weapons usually takes place from the side or from above.
  • the armor element 2 When executing according to 2 the armor element 2 is movable in front of the surface 11 of the object 10 to be protected in the vertical direction R 1 as well as in the horizontal direction R 2 .
  • the movement of the armor element 2 in relation to the object 10 also results in a relative movement in relation to the impinging laser beam, which is why it does not hit one and the same point over longer periods of time, with the result that the local energy input becomes clear is reduced, so that destruction of the armor element 2 is not to be feared.
  • the representation in 2 shows two directions of movement of the armoring element 2 in a surface parallel to the surface 11 of the object 10 to be protected, it is also conceivable to move the armoring element 2 additionally or alternatively transversely to the direction of the surface 11 to be protected. Such a movement moves the armor element 2 in the direction of the impinging laser beam.
  • the laser beam emanating from the laser weapon is usually focused directly into the surface of the object 10 since the intensity of the laser radiation is greatest in the focus.
  • the armoring element 2 can be moved out of this focus position, as a result of which the intensity of the laser radiation is reduced at its point of incidence. This also makes it possible to reduce the risk of armor-plating element 2 being destroyed by the impinging laser radiation.
  • the movements of the armor element 2 can be initiated via a drive M.
  • the drive M can be a motor drive, such as an electric, hydraulic or pneumatic motor.
  • the armor element 2 can be set in motion in a defined manner via the drive M, for example via a type of eccentric gear or similar devices. Since it is not necessary to keep the armored element 2 constantly in motion, a sensor system S is also provided for detecting the incident laser radiation. These can be light-sensitive sensors that detect the incident laser radiation. After detecting the laser radiation, the drive M can then be controlled and the armored element 2 can be set in motion.
  • the armor element 2 can alternatively or additionally also be resiliently suspended, as is shown in 6 is shown. It can be seen that the armor element 2 is coupled to the object 10 to be protected via a spring 4 .
  • a resilient suspension is particularly suitable for mobile objects 10 and in particular for military land vehicles. Due to the forces occurring during driving, the armor element 2 is constantly kept in motion by deflecting the spring 4 .
  • Another advantage of this suspension via springs 4 is that the movement occurs purely stochastically, so that it is not possible to track the laser radiation in accordance with the movements of the armor element 2 .
  • the Schtschutz 3 is on the threat side of the armor elements 2 of the laser armor 1 and covers them to the threat side at least partially.
  • the armoring elements 2 are located in an intermediate area between the protective device 3, which is arranged in a fixed position opposite the object 10, and the object 10. A kind of gap results, in which the armoring elements 2 can be moved.
  • the purpose of the Schtstoff 3 is to make the movements of the armor elements 2 invisible to the attacker.
  • the protection 3 is designed in such a way that it covers the edges 2.1 of the armor elements 2 in such a way that they lie in the shadow of the protection 3, see also the illustration in FIG 2 .
  • the overlapping of the edges 2.1 of the armoring element 2 is selected in such a way that they do not protrude from the shadow of the armoring element 3 even with maximum movement of the armoring element 2.
  • the movement of the otherwise flat armor element 2 cannot be recognized and it is in any case not easily possible to follow these movements with the laser beam.
  • Schtschutz 3 An alternative embodiment of the Schtschutz 3 is in 4 shown. While Schtschutz 3 in the 2 and 3 in each case only covers the edges of the armor element 2 and otherwise has openings for the passage of the laser radiation, covers the protective shield 3 according to FIG 4 the armor elements 2 over the entire surface. In this arrangement, the armor elements 2 are distributed in tiles over the object and lie completely in the shadow of the protective shield 3.
  • the protective shield 3 is kept optically transparent in a narrow-band wavelength range, for example in the wavelength range of 1064 nm. The optically transparent wavelength range is matched to the wavelength of the expected laser weapon, continuing the wavelength example above to an Nd:YAG laser. The effect achieved by this is the following:
  • the protective shield 3 is optically transparent to the impinging laser beam, the laser beam passes through the protective shield 3 almost unhindered and hits the armored element 2 , which moves relative to the object 10 .
  • the movements of the armor element 2 are not visible to the attacker since the wavelength of the laser radiation is often outside the range visible to the human eye or at least difficult for the attacker to see due to the narrow band of the optical transparency of the armor 3 .
  • the attacker is therefore presented with an image in which the laser beam virtually disappears into the protective shield 3 without here produce a significant effect. Because even if one of the armor elements 2 were to be destroyed, the attacker 2 would not be able to see this because of the armor protection 3 .
  • the protective elements 2 are arranged in several layers L1 , L2, resulting in a redundant arrangement such that if one of the armored elements 2 of an outer layer L2 fails, in a next step the laser radiation is directed to a further inner layer L1 meets.

Details of the movement of the armor elements 2 and the cooling system 13 are in the Figures 15 to 18 not shown for reasons of clarity.
  • the armor elements 2 each have a multiplicity of optical active bodies 23, 24, 25 for impairing the incident laser radiation. This results in a weakening of the intensity of the laser radiation and thus a reduction in the required cooling capacity of the cooling system 13 . Laser beams with an intensity above the damage threshold of the object 10 to be protected are prevented from affecting the latter.
  • the active bodies 23 are designed as reflection bodies 23 and are located as loose bulk material in a box-shaped receptacle 2.4 of the armor element 2.
  • the optical active bodies 23 have a surface 23.1 consisting of an optically reflecting layer.
  • the reflecting surface 23.1 can extend over the entire optical active body 23 or only over partial areas of the active body 23.
  • the submunitions 23 according to the embodiment in 15 have several surfaces 23.1 extending at an angle to one another, resulting in very different reflection planes.
  • the in is based on a different physical operating principle 16 shown armor element 2.
  • a multiplicity of optical active bodies 24, some of which have different geometries, are also provided.
  • An impinging laser beam, such as one in 16 is shown as an example in solid lines, affected by refraction, whereby the laser beam widens and thereby loses intensity.
  • the laser beam is not only impaired by the refraction effects but also by reflections at the boundary surfaces of the active bodies 24.
  • the active bodies 24 are designed as optically transparent refracting bodies 24 for refracting the laser radiation.
  • the active bodies 24 can have different geometries. It is important that these have surfaces angled towards one another or round surfaces on which the light is then refracted.
  • the submunitions 24 as shown in 16 also be so-called beam splitters, which let through parts of the laser radiation with a specific beam property and reflect other parts of the laser radiation that do not have these beam properties.
  • beam splitters For example, p- and s-polarized beam components can be separated from one another, which also results in a significant reduction in the incident laser intensity.
  • polarization filters can be provided on the active bodies 24 .
  • the in 17 shown submunitions 25.
  • a diffraction body 25 This can also according to the illustrations in the 15 or 16 can be introduced into an armor element 2 as loose bulk material.
  • a diffraction body 25 At the in 4 active body 25 shown is a diffraction body 25. This has several diffraction gaps 25.1, at which the incident laser light is diffracted. Diffraction patterns result with a less intense laser radiation on the surface of the object 10 to be protected.
  • the submunitions 23, 24, 25 can always be stored as loose bulk material within a housing-like receptacle 2.4 of the Armor element 2 are arranged.
  • different active bodies 23, 24, 25 with reflective, refractive and diffractive properties can be arranged mixed, preferably as loose bulk material.
  • the receptacle 2.4 has a box-shaped geometry and is provided with an optically transparent cover in the manner of a lid on the threat side.
  • the cover can be designed to be optically transparent in the area of the expected laser radiation in a narrow-band wavelength range. This means that the impinging laser beam passes unhindered through the cover and is only impaired by the submunitions 23, 24, 25 behind it. Destruction of the cover is avoided in this way.
  • Another positive effect occurs with covers that are optically transparent in a wavelength range that is outside the range of wavelengths that can be perceived by the human eye. Because with these, for example, a laser beam in the IR range passes through the cover, behind which it is then impaired by the optical active bodies 23, 24, 25. Since this is imperceptible to the human eye, the attacker cannot easily recognize these effects.
  • a large number of submunitions 23, 24, 25 are embedded in a carrier material, which can be applied to the threat side of the armor element 2. Similar to sunscreen cream, a large number of smaller active bodies 23, 24, 25 can be embedded within the carrier material. When a laser attack is detected, the carrier material and with it the submunitions 23, 24, 25 can then be deployed in a targeted manner on the endangered side of the object 10 to be protected. For this purpose, for example, a corresponding line system with several outlet nozzles for applying the active bodies 23, 24, 25 arranged in the carrier material to a threatened area of the object.
  • submunitions 23, 24, 25 are in 18 shown.
  • the incident laser radiation can be impaired by reflection, refraction or diffraction in such a way that the intensity of the laser radiation is weakened regardless of the direction of incidence of the incident laser beam.
  • the risk of material failure as a result of very intense radiation is significantly reduced.
