Today the high-speed galvanometer mirror is used to control the x and y directions of scanning lasers. These devices are used in many applications from laser light shows and laser marking, to laser machining, wafer dicing, barcode readers, and laser ablation. The mirrors are attached to high-speed, limited rotation dc motors and the motion is governed by an internal position detector to allow feedback control of the motor. This is done through a signal that provides position information that is proportional to the rotation of the motor.
Nutfield has recently introduced a new laser scan head with a galvanometer mirror that controls the laser in a three-axis configuration. Called the Contour, it allows for intricate engraving of contoured surfaces.
