Military laser range safety

Abstract

The Army uses lasers to measure the distance to a target, to mark a target for laser-guided weapons or to simulate direct-fire weapons in tactical training. These systems are respectively called laser rangefinders (LRFs), laser target designators (LIDs), or laser direct-fire simulators (LDFSs). There are devices that perform both fire control functions of ranging to, and marking targets. The LRFs and LTDs are laser hazard Class IIIb or IV while the LDFS are at the low end of Class IIIb (marginally above the Class I limit) but have been described as safe for use in the training environment.. No range controls are required for the MILES other than instructions to users warning them not to stare into the laser device between 7 and 12 meters and not to point the MILES transmitters at the face or eyes of another individual at close range. On the other hand, the LRF/LID fire control lasers can cause serious retinal injury with permanent visual loss and these systems require strict control. Current fire control lasers do not exceed skin exposure limits.The Army uses lasers to measure the distance to a target, to mark a target for laser-guided weapons or to simulate direct-fire weapons in tactical training.
