Abstract:
An optical deflecting device includes a mirror having a reflecting surface and a support unit to support the mirror. The support unit includes a first drive unit. The first drive unit includes a plurality of continuously meandering first beams and a plurality of first piezoelectric members respectively provided to the plurality of first beams to swing the mirror around a first axis to deflect light incident on the reflecting surface of the mirror. Two voltages having non-similar waveforms are respectively applied in parallel to each two of the first piezoelectric members respectively provided to adjacent two of the first beams.
