Laser marking is an important branch of the laser information processing technology. The existing laser marking controllers are most based on PC and Windows operating system, which is large and inconvenient to move. Still, it can't work outdoors or in other harsh environments. In order to compensate for these insufficient, this paper proposed an embedded laser marking controller based on ARM and FPGA processor. Based on the principle of laser galvanometer scanning marking, the hardware and software were designed for the application.
