A starship phaser range.
The phaser range is a facility aboard some starships, that allow Starfleet personnel to practice aiming and firing their phasers. It consists of a circular stage set in a large empty area. The area around the stage is illuminated, but everywhere else is dark. Flashing spheres of light of different colours and moving at various speeds serve as the targets. Two people can be accommodated on the stage at any one time. (TNG: "A Matter of Honor", "Redemption, Part I")
