This optical scanning method yields a high quality image regardless of the size of the scanning area. An emission end of an optical fiber is displaced two-dimensionally to scan light emitted from the optical fiber, the emission end being displaced by an optical scanning actuator that includes a first driver and a second driver for driving the emission end in different directions. A non-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, and to change a length of the scanning pattern in accordance with a rotation angle of the scanning pattern.
An optical scanning method for displacing an emission end of an optical fiber two-dimensionally to scan light emitted from the optical fiber, the emission end being displaced by an optical scanning actuator that includes a first driver and a second driver configured to drive the emission end in different directions, the optical scanning method comprising:
