Abstract
An optical device includes a light source, a controller that supplies control information to the light source and controls an output level of the light source, a monitor that outputs an operation state of the optical output as a monitor output, and an auxiliary controller that records the monitor output and the control information. When the controller stops supplying the control information, the auxiliary controller outputs the control information to the light source in accordance with the relation between the recorded monitor output and the recorded control information.
