Abstract
In an optical deflector apparatus including a mirror, an inner frame, an outer frame, an inner piezoelectric actuator adapted to flex the mirror around an axis of the mirror, an outer piezoelectric actuator adapted to flex the mirror around the axis of the mirror, and a driver adapted to generate an offset drive voltage and a rocking drive voltage. The offset drive voltage is applied to a first piezoelectric actuator selected from the inner piezoelectric actuator and the outer piezoelectric actuator. The rocking drive voltage is applied to a second piezoelectric actuator different from the first piezoelectric actuator.
