In a two-dimensional optical deflector apparatus comprising an optical deflector and a driver for driving the optical deflector, the optical deflector includes a mirror, a first piezoelectric actuator for rocking the mirror with respect to a first axis of the mirror, and a second piezoelectric actuator of a meander type for rocking the mirror with respect to a second axis of the mirror perpendicular to the first axis. The driver generates a curved-type saw-tooth drive voltage and applies the curved-type saw-tooth drive voltage to the second piezoelectric actuator. |
