摘要:
A scanning endoscope apparatus includes: a light source unit an illumination fiber inserted inside an insertion portion of an endoscope, the illumination fiber being configured to guide illuminating light from a proximal end to a distal end an actuator configured to drive the distal end of the optical fiber so that the illuminating light outputted from the illumination fiber is scanned on a subject a memory configured to store correlation coefficient information on a correlation coefficient between a drive signal for driving the actuator and a displacement amount of the actuator and a controller, and the controller detects a current of the drive signal for driving the actuator and corrects the drive signal for driving the actuator based on the correlation coefficient information and a value of the detected current so that the displacement amount of the actuator becomes a predetermined value.
