- a housing part 4 shows a housing part 4 with a pivotable rod antenna 53 and with a snap or fixing device 54 for this antenna 53.
- a receiver optics 48 can be present on the front side of the housing part 4 .
- FIG. 5 shows a target device 6 provided for the equipment of soldiers, hereinafter also referred to as a belt device 6 , for combat purposes with a large number of electrical or electronic components.
- a belt device of this type is known for example from DE-OS-40 03 960 A1 .
- the belt device 6 according to FIG. 5 carries sensors 61, 62, 63, 64, 65, 66, 67, which are preferably equipped with a special electronic circuit.
- this belt device carries one or more LED transmitters 68, 70 and a GPS and a control unit 7, optionally with a battery.
- the pulsed CW continuous wave laser 8 is connected to a modulator 81 and comprises, for example, a laser diode 82, a feedback diode 83 coupled to it , an operational amplifier 84 and a transistor 85 as well as some resistors 86, 87 and 88.
- the anode of the diode 82 and the cathode of diode 83 are jointly connected to a voltage source 89 (positive pole), for example a battery of 3 to 5 volts.
- the cathode of the diode 82 is connected to earth (negative pole) via the series connection of the resistor 86 and the emitter-collector path of the transistor 85 .
- the amplifier 84 with the resistor 87 connected downstream is inserted between the anode of the diode 83 and the base of the transistor 85 .
- the base of transistor 85, which forms the modulation input of the circuit is connected to ground via resistor 88 .
- a reference potential can of course also serve as earth.
- the modulator comprises a circuit 81 which not only effects a coding function, but also a chopper function or chopper function in order to include a light signal of the (carrier) frequency ft before coding, which is carried out at a bit rate of the frequency fd to chop a chopper frequency fz.
- the sensors 61 to 67 according to FIG. 5 contain a sensor circuit 9 according to FIG. 7.
- the circuit 9 comprises, for example, a detector diode 91, the cathode of which is connected on the one hand to the input of an amplifier 92 and on the other hand via a coil 93 to the one connection of a capacitor 94 is connected.
- the output of the amplifier 92 is connected via an integrator filter 95 to a microprocessor 96 , the output signals of which are fed to the control unit 7 via cables.
- the identification system or friend-foe detection system operates under two different environmental conditions, depending on whether the target soldier is in open terrain or in cover. If, in a scenario with open terrain, a soldier A wants to identify a soldier B who is not in cover (in FIG. 5, this would be without bush 12 ), he sets his weapon-mounted laser target illumination device 1 into operation and " shoots "Soldier B with a laser beam 11 from the laser target illumination device 1. A coded message 13 transported by the laser beam 11 requires soldier B to identify himself. A belt device 6 on soldier B receives the coded message 13, which is composed of a signal from soldier A comprising, for example, 116 bits.
- a sensor for example 63 on the belt device 6 from soldier B, recognizes the 116-bit signal, which is composed as follows: soldier number / security code / possibly GPS data / form of the answer.
- Soldier B will now receive the coordinates of soldier A , and an LED transmitter 68 on the belt device 6 of soldier B will transmit a confirmation code.
- the confirmation code can be freely selected by the unit using the system. For example, it can consist of the name of Soldier B, the battalion, the location (GPS coordinates) or any other terms.
- soldier A is not only equipped with a laser transmitter 3 , but also has a laser receiver , optionally accommodated in the housing part 4, with a receiver optics 48, which is mounted parallel to the laser transmitter, that is to say to the laser lighting part 3.
- the laser receiver now receives diffuse light emitted by LED transmitter 68 or 70 from soldier B.
- Soldier A sends an identification code until he receives confirmation from soldier B. If soldier B belongs to his own party, soldier A sees a red alarm signal in red dot 41 and / or in illuminated zone 42, which prohibits him from fighting soldier B. This alarm signal appears in the system in such a way that it can only be seen by soldier A and not by the enemy.
- soldier A receives the confirmation signal for example via the receiver optics 48 in the LED-receiver 49 of his device 1, an appropriate target illumination device 3 of the laser device 1 of soldier B is not used as an infrared transmitter to return to the confirmation signal to soldier A, because the laser target illuminator 3 emits a light beam that is focused too sharply.
- This narrow beam of light preferably oriented at an angle of approximately 0.5 mrad, could not send the confirmation signal back to soldier A , since soldier B does not necessarily know the position of soldier A. Therefore, a high-performance LED transmitter 68/70 (LED light emitting diode) is used to return the confirmation code, which is also attached to the belt device 6 of soldier B.
- This LED transmitter 68/70 emits its light output in a much larger solid angle, which is why soldier B's confirmation can be received by soldier A under all circumstances. As long as soldier A can see soldier B, he will be able to receive the confirmation signal.
- the weapon 2 Since the fighting takes place increasingly in poor lighting conditions, it is becoming increasingly common to equip soldiers participating in the fighting with night vision glasses. If this is the case, the weapon 2 is usually guided by the soldier in the hip stop. The observation and aiming process takes place along the laser beam 11, which is visible through night vision glasses (not shown). As a result of the hip position of the weapon 2 , the red alarm signal ( 41 and / or 42 ) is not visible to the soldier carrying the weapon 2 .
- the laser target illumination device 3 is controlled by a microprocessor, it is easily possible to alternately switch the laser beam 11 on and off instead of or in addition to the red alarm signal.
- the soldier equipped with night vision goggles can quickly and easily capture the alarm signal via the laser beam and thus identify the illuminated soldier as belonging to his own party.
- the soldier A can remove the body from. Only partially see soldier B. Soldier A shoots again with laser beam 11 as described above.
- the belt device 6 from soldier B will nevertheless detect the laser beam from soldier A because the overall system has sufficient sensitivity for this type of application, for example in that the sensors 61, 62, 63, .... are each equipped with special electronics, which can be powered by a common battery or possibly also by a single small battery.
- the main problem is that soldier B's LED transmitter 68 can be completely shielded by bush 12 and soldier A does not receive soldier B's response. Soldier A can only receive light directly from LED transmitter 68/70 because the light is diffused and not directed.
- soldier A receives no confirmation within a time period Ta of, for example, 100 ms after transmission of the laser beam, but soldier B would obviously be able to receive messages from soldier A , soldier B is given a second chance by sending out a pulse sequence via one the belt device 6 attached radio unit 71, which may include a radio transmitter or radio transceiver, to transmit a confirmation.
- Radio unit 71 which may include a radio transmitter or radio transceiver, to transmit a confirmation.
- Soldier A can receive this radio signal in all conceivable circumstances, but because of its vulnerability to enemy countermeasures, it should only be used if other means fail. Enemy forces could also send radio signals of their own soldiers to be tracked or not identified. If soldier B is an enemy, there is no response to the query caused by soldier A's coded laser beam in either of the scenarios described above.
- the time period Tb can be, for example, between 1 ms and 1 s, but is preferably 100 ms, and Tc can be selected to be approximately equal to or greater than 0.1 ms, preferably approximately 1 ms or greater, for this pulse wave.
- the radio unit 72 can also comprise a radio transmitter or a radio transceiver. This pulse sequence can be received over a distance of several kilometers under all conceivable circumstances.
- the system will identify the illuminated target as an enemy object. Overall, a time of 200 ms is required for this process. If soldier A wears night vision goggles, he will see through the night vision goggles the continuously emitted laser beam that identifies an illuminated soldier as an enemy.
- the sensors 61, 62, 63, ... are preferably designed in the form of round disks, and with a relatively high thickness that they are not only sensitive to the laser beam on the surface but also on the side, that is to say on the periphery of the disk , This means that the detector 91 ( FIG. 7 ) is also distributed in a corresponding form over the cylindrical surface of the disks ( FIG. 9 ).
- the laser beam is chopped, as mentioned above, so that the detector 91 detects intermittent radiation, which it converts into an alternating current of the same frequency fz with the aid of the resonance kernel formed by the coil 93 and the capacitor 94 .
- the resulting AC voltage at the input of amplifier 92 is amplified very strongly by the latter.
- the output signal of the amplifier 92 is fed to the integrator filter 95 , which emits the coded signals to the microprocessor 96 for evaluation. Signals evaluated from this are then supplied by the microprocessor 96 to the control unit 7 .
- the pulse width of the emitted chopped laser pulses is, for example, between 10 ns and 100 ⁇ s and preferably between 0.1 and 10 ⁇ s.
- the width of an information bit pulse preferably corresponds to the width of a number of 3 to 50 chopped laser pulses.
- a lever 47 (folded upwards) can also be used to trigger the laser device instead of one of the control buttons 45 or 46 ( FIG. 2 ).
- the upper part of the laser device preferably forms two semi-cylindrical parallel ones Chambers or partially cylindrical sections, the between these chambers existing gap allows unobstructed view of the target. Because this gap is wide enough, a red dot can be in a further embodiment of the invention just be housed laterally in this gap, preferably in End region of the gap where the light beam is emitted, such that the Soldier can see the target and this red dot at the same time.
- the laser device preferably emits light at a wavelength in the range of 780 to 1000 nm, for example of 820 nm, for example with an output power in the order of 50 mW.

- the center of the printed circuit board 624 there is at least one further photosensor 630, the sensitive side of which is directed against the cover 611 of the housing and is therefore suitable for the detection of laser beams 631, 632 which are incident with a greater inclination to the surface of the bottom 611 than that Laser beams 620 and 619, which propagate almost parallel to this floor area.
- an individual preamplifier 92 and an integrator filter 95 are preferably accommodated in the housing 610 in order to obtain an alternating electrical signal as individual means from a received chopped laser radiation and to supply the already discriminated signals to the control unit 7 via lines.
- the coil 93 and / or the capacitor 94 which form the resonant circuit as sensor means, can be accommodated or integrated in the printed circuit board 624 .
- the discriminator and / or the microprocessor can be designed to filter out only signals with an expected coding from the received laser radiation.
- a sensor according to FIGS. 8 and 9 is consequently designed in the form of round disks with the diameter / thickness ratio resulting from the figure.
- the incident laser radiation can be reflected in the body of soldier B and can reach the radiation-sensitive side of the photosensor 625 laterally, for example as laser radiation 619 or 620 ( FIG. 9 ), through the peripheral thickening 618 .

Each synchronization message contains a special synchronization code in its data header 136 ( FIG. 13 ) as well as the belt system ID of the control unit in its data block. Each controlled unit checks whether at least one synchronization message with the belt system identification code has been received within a given period of time. If not, this unit assumes that it has been removed from its control unit. It then begins to search for any synchronization message and, if such a message is found, retrieves its belt system ID from its data block 137 ( FIG. 13 ) and sets its belt system ID storage unit to this new belt system ID. This enables the replacement of belt system components. If a belt system component is transferred from one soldier to another, the soldier will automatically compare their identification code with that of the belt system components in his immediate vicinity.

- the command center 141 is equipped with a second radio transceiver 142 , which ensures data connections to the radio transceivers 132 ( FIG. 12 ) of the control units 101 ( 125 ) ( FIG. 10 ) of the belt systems of the soldiers.
- This connection is used by the control units to transmit status information of each soldier (such as his position, emergency calls, determined hits, etc.).
- the command center can use this connection to transmit commands such as "retreat" or "attack”.
- each receiver / transmitter 142 includes one or more second ultrasound transducers 143, which can be used to communicate with the first ultrasound transducers 126 of the belt systems.
- Second receiver / transmitter 142 can e.g. B. Detect the presence of soldiers in a given area (e.g. in a room) and thereby determine further information for the command center. They can also be used to transmit data from command center 141 to all soldiers in the given area.

- the holographic grating 234 is rotatably mounted about a hinge 235 . The rotation takes place by means of a button, not shown, attached outside the housing. When this grating is moved to its horizontal position 234a , it does not affect the light beam. In its vertical position, the divergence of the light beam is increased to 10 mrad.
- a beam splitter 239a is attached between lenses 232 and 233 to direct light emerging from the laser device into detector 239b .

If the laser light source is operated together with the holographic grating 234 , as a result of which the emerging light beam has a divergence of 10 mrad, the range is approximately 2 km, but without a holographic grating 234 it is more than 10 km due to the reduced divergence to 0.2 mrad. The aiming process is facilitated at distances of less than 2 km by the inserted holographic grating 234 .
- a laser emitting in the near infrared ie at a wavelength of less than 1000 nm
- semiconductor lasers which emit in these wavelength ranges can be operated in a continuously emitting manner. This allows the emitted light to be modulated precisely in a simple manner (pulse code modulation / chopper), which improves the signal-to-noise power ratio in the emerging light beam

- a corresponding design of the holographic phase grating additionally provides a uniform illumination of an area between the ring 307 and the light spot 306 , which is depending extends outside of the ring 307 if necessary.
- the position of the center of the circle 307 in the target plane is critical with regard to the perpendicular incidence of the light beam into the holographic phase grating, but a shift of the grating perpendicular to the optical axis only causes an uneven thickness of the ring 307.
- the total light output emitted by the target device should preferably be higher in these positions than in the middle position of the holder.

- the laser beam used for identification can preferably be coded in this way and / or chopped that the object to be identified is communicated, in what way or on which channel or in which frequency band sequence a reply should be sent. This brings the big one Advantage that the laser path makes it impossible to spy on the frequencies, because nobody can know on which frequency or which frequency band one Response is expected.
- the laser beam can also be bundled in such a way that the objects of a group can be identified individually. Furthermore, the laser beam is also used to send messages for voice and video images become.
