Laser scanning device and laser scanning system

A laser scanning device, comprising:

• a system on chip structure configured to receive and process a graphic data transmitted by an external computer to generate a galvanometer movement instruction and a laser control instruction, wherein the system on chip structure comprises:
• a processor module configured to receive the graphic data transmitted by the external computer and perform a coordinate correction and a track planning for the graphic data to generate the galvanometer movement instruction and the laser control instruction;
• a logic processing unit configured to obtain the galvanometer movement instruction and the laser control instruction in accordance with a control period;
• a galvanometer servo control module configured to receive the galvanometer movement instruction from the logic processing unit, and calculate a galvanometer drive voltage according to a position and a current feedback value of a galvanometer;
• a laser control module configured to receive the laser control instruction from the logic processing unit, and generate a laser control signal in accordance with a control time sequence of the laser and a feedback status of each galvanometer;
• and
• an IO control module, connected to the logic processing unit, and
• the a galvanometer configured to receive the galvanometer movement instruction and move according to the galvanometer movement instruction;
• wherein the laser control instruction is transmitted to an external laser, so that the laser and the galvanometer move synchronously.
