LASER OUTPUT CONTROL METHOD, A LASER OUTPUT CONTROL DEVICE, AND A LAYER PROCESSING SYSTEM INCLUDING THE SAME CAPABLE OF CONTROLLING THE INTENSITY OF LASER OUTPUT ACCORDING TO A MOVING SPEED CHANGE OF A LASER OUTPUT DEVICE

摘要

PURPOSE: A laser output control method, a laser output control device, and a layer processing system including the same are provided to control the intensity of laser output from a laser output device by adaptively controlling a duty ratio of a pulse width modulation signal.;CONSTITUTION: A moving speed change of a laser output device, operated based on a pulse width modulation signal, is detected(S120). A duty ratio of the pulse width modulation signal is controlled based on the moving speed change(S140). The intensity of the laser output of the laser output device is controlled based on the duty ratio(S160). The duty ratio of the pulse width modulation signal corresponds to a ratio of an on-section for an off-section.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S120) Detecting moving speed change of a lase output device; (S140) Controlling a duty ratio of a PWM signal provided from a laser output device based on a moving speed change; (S160) Controlling the intensity of laser output based on a duty ratio of a PWM signal
