Galvanometer scanner controller for laser processing apparatus

PURPOSE: A galvanometer scanner controller for a laser processing apparatus is provided to transmit laser processing data to the galvanometer scanner controller through serial communication. CONSTITUTION: A galvanometer scanner controller(130) for a laser processing apparatus comprises a control signal generation unit, an analog conversion unit, and a galvanometer scanner drive unit. The control signal generation unit calculates the processing position of an object by receiving laser processing data from an external terminal and outputs a digitized control signal for powering a galvanometer scanner(120). The analog conversion unit converts the digitized control signal into an analog control signal. The galvanometer scanner drive unit drives the galvanometer scanner depending on the control signal.
