Mirror galvanometers play an vital role in many laser marking systems. They are a type of electromechanical instrument that indicates the sensing of an electric current by deflecting a laser beam with a mirror. Mirror galvanometer was first invented in 1826 by Johann. C. Poggendorff, and has been used extensively in scientific instruments before reliable, stable electronic amplifiers were available. The most common uses were as recording equipment for seismometers and submarine cables used for telegraphy. Today, the term mirror galvanometer is also used for devices that move laser beams by rotating a mirror through a galvanometer set-up. Such a device is usually call a galvo system.
