The galvanometer scanner is a type of laser beam steering device that uses a pair of rapidly moving mirrors to deflect the laser beam in different directions, allowing for precise and fast laser processing. It is commonly used in various laser applications, including marking, engraving, welding, cutting, and scanning systems such as LIDAR for autonomous vehicles. Galvanometer scanners are known for their high accuracy, speed, and repeatability, making them a popular choice in industries where precision and efficiency are critical.
