By arranged in the beam path of the laser beam sight protection, the movements of the armor element for the attacker are not visible. The privacy screen is located on the threat side of the armor element. 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 armor element, in order to deliberately take a certain point of the armor element under continuous firing.
  • the privacy shield covers at least the edges of the armor element. Covering the edges of the armor element is sufficient in most cases, since the movement of a particular plate-shaped armor element can usually only be seen at the edges.

  • An advantageous for the protective effect of the laser armor embodiment provides that the armor elements are arranged in multiple layers. The result is a redundant arrangement of armor elements such that in case of failure of an outer layer of armor elements of the laser beam strikes a more inner layer.
  • each layer has a plurality of armor elements, wherein the directions of movement of the armor elements are different in two adjacent layers.
  • the Armor elements are automatically set in motion. It is not necessary to constantly move the armor elements, but only in the case of a specific threat situation, which is reliably detected by the sensors.
  • the heat introduced via the laser weapons into the armor element is dissipated via a cooling system and the cooling system is activated via a sensor which detects the laser radiation. It results in the already described in connection with the laser armor advantages. Also in the method, it is advantageous if the armor element is designed according to one or more of the aforementioned features.

These may be photosensitive sensors which detect the incident laser radiation. After detecting the laser radiation, the drive M can then be activated and the armor element 2 can be set in motion.
  • the armor element 2 may also be suspended resiliently, as in Fig. 17 is shown. It can be seen that the armor element 2 is coupled via a spring 24 to the object 10 to be protected. Such 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 kept constantly in motion by deflecting the spring 24. Advantage of this suspension via springs 24 is also that the movement purely stochastic takes place, so that a tracking of the laser radiation according to the movements of the armor element 2 is not possible.
  • a screen 23 is provided, which will be discussed in detail below.
  • Fig. 14 Like the illustration in Fig. 14 can first be seen, is the screen 23 on the threat side of the armor elements 2 of the laser armor 1 and covers this to the threat side at least partially.
  • the armor elements 2 are located in an intermediate region between the fixed object visually arranged against the object 10 screen 23 and the object 10. It results in a kind of gap in which the armor elements 2 can be moved.
  • the purpose of the blinds 23 is to make the movements of the armor elements 2 invisible to the attacker.
  • the screen 3 is designed so that it covers the edges 2.4 of the armor elements 2 such that they lie in the visual shadow of the screen 23, see. also the representation in Fig. 2 ,
  • the overlapping of the edges 2.4 of the armor element 2 is chosen such that they do not emerge from the visual shadow of the privacy screen 23 even with maximum movement of the armor element 2.
  • the movement of the otherwise planar armor element 2 is therefore not visible and it is certainly not readily possible to track the laser beam these movements.
  • FIG Fig. 15 An alternative embodiment of the screen 23 is shown in FIG Fig. 15 shown. While the screen 23 in the FIGS. 13 and 14 only covers the edges of the armor element 2 and otherwise openings for the passage of the Laser radiation has, covered the screen protector 23 according to Fig. 15 the armor elements 2 full surface. The armor elements 2 are arranged in this arrangement tiled over the object and are completely in the visual shadow of the screen 23.
  • the screen 23 is held in this embodiment in a narrow-band wavelength range, for example in the wavelength range of 1064 nm optically transparent.
  • the optically transparent wavelength range is matched to the wavelength of the expected laser gun, continuing the above wavelength example to an Nd: YAG laser. The effect achieved by this is the following:
  • the privacy screen 23 Since the privacy screen 23 is optically transparent to the incident laser beam, it passes through the privacy screen 23 virtually unhindered and strikes the armor element 2, which moves relative to the object 10. However, 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 to recognize due to the narrow band of optical transparency of the screen 23 for the attacker. The attacker therefore has an image in which the laser beam virtually disappears in the privacy screen 23 without causing a significant effect here. Because even with the destruction of one of the armor elements 2, this would not be visible to the attacker 2 due to the privacy screen 23.
  • FIG. 18 An improved in terms of their protective effect embodiment finally shows the illustration in Fig. 18 ,
  • the armor elements 2 in several layers L 1 , L 2 are arranged, resulting in a redundant arrangement such that in case of failure of one of the armor elements 2 an outer layer L 2, the laser radiation in a next step to a further Inner layer L 1 meets.
  • the movements of the armor elements 2 are advantageously oriented differently in the layers L 1 , L 2 .
  • the armor elements 2 may consist of armored steel and be formed by type ballistic armoring plates.
  • the protective plates may also be composite armor plates in which a multiplicity of ballistically active active bodies, for example of a ceramic material, are embedded in a matrix material.
  • a configuration with a plurality of optical active bodies 13, 14, 15 can also be provided.
