laser grids
Intruder detection system
Laser grids are networks of intersecting laser beams used for detection, measurement, or security.
In security systems, breaking a beam triggers an alarm—a staple of heist movies where thieves contort through visible red lines: She carefully stepped through the laser grid.
Industrial laser grids measure alignment or create cutting guides.
The term also appears in science fiction for force fields or weapon systems.
