Abstract
This optical scanning method yields a high quality image. An emission end of an optical fiber is displaced two-dimensionally to scan light emitted from the optical fiber, the emission end being displaced with an optical scanning actuator that includes a first driver and a second driver for driving the emission end in different directions. A circular scanning area is scanned by controlling, with a driver controller, a first drive signal supplied to the first driver and a second drive signal supplied to the second driver so as to rotate a scanning pattern of the light while causing the scanning pattern to reciprocate repeatedly in a nearly parallel manner with constant length.
