laser grid
Crisscrossing light barrier
A laser grid is an array of intersecting laser beams forming a visible net pattern, typically used in security systems to detect intrusion.
The image of a thief contorting through a laser grid to avoid triggering alarms is a staple of heist movies: She somersaulted through the laser grid without breaking a single beam.
The term also appears in science fiction for force fields or weapons systems.
