This paper proposes a method of single-lens barrel double-beam laser communication and the application scheme in injury simulation of actual soldiers combat,and designs a single tube double beam structure.The beam emitted from the laser device is divided into inner and outer parts with different divergence angles,and the energy density of the inner ring is higher than that of the outer ring.the receiving probe is connected to two voltage comparators with different limits to distinguish the irradiation of the inner and outer ring beams,and the appropriate probe array is design,so that the position of the center of the spot can be judged according to the combination of the high and low levels of the output of the comparator and the position of the probe.Therefore it can more accurately judge the injury and identify the near ammunition,which is of great significance in the simulation of actual training injuries.
