Laser transmitter is able to trigger any of the four receivers at the distance of 1.5 km (LAM-1), i.e. 5 km (LAM-2) using different codes for the receivers’ activation. We select the codes 1, 2, 3 or 4 on the transmitter and aim the transmitter toward the receiver with the same code. During mine activation the receiver must be aimed inside the circular reticule of the transmitter’s optical sight. By pressing the trigger, the laser transmitter is activated and it then transmits the coded package of impulses toward the receiver. It is necessary to ensure optical visibility (without obstacles) between the transmitter and receiver so that the receiver could detect the transmitter beam. The system range can be extended to 15 km in the good atmospheric conditions.
