A soldier carries a weapon on which a laser device (1) is mounted, which is used for illuminating a harness device (6) on the body of another soldier. This harness device is provided with sensors (61, 62, 63, . . . ), which perform detection tasks for several applications in connection with arbitrary simulation scenarios in the course of exercises and battles. The laser device (1) has a laser target illumination element which is designed for transmitting tightly bundled laser beams (11), as well as chopper means for transmitting laser beams which are not only coded, but also chopped at a predeterminable frequency. The sensors contain tuning means for obtaining an alternating electrical signal from the received chopped laser beams, which is supplied to a pre-amplifier connected upstream of a discriminator. A very sensitive laser identification system results due to the fact that the electrical signal obtained in this manner can be very strongly amplified.
A laser identification system comprising at least one laser device for identifying at least one target device, wherein said laser device is designed to transmit a coded laser beam, and wherein said target device has sensor means for detecting this laser beam and converting it to electrical signals, which are provided to a discriminator, and said target device also contains transmitting means for returning reports on the basis of decisions made in the discriminator to receiver means located inside or outside of the laser device,
