Patent ID: 8587853

Claim:
A two-dimensional optical scanner comprising: a movable portion including: a mirror portion configured to reflect a beam of light incident to the minor portion; and a first driving portion configured to oscillate the mirror portion around a first axis, the first driving portion comprising a piezoelectric body; a second driving portion configured to oscillate the movable portion around a second axis perpendicular to the first axis, the second driving portion includes: a coil configured to be supplied with a driving electric current, and a generator configured to generate a magnetic field; and a driving controller configured to drive the first driving portion in a first driving method in which a driving signal is supplied to the piezoelectric body in a resonant condition, and configured to drive the second driving portion in a second driving method in which the driving electric current is supplied to the coil such that the driving electric current supplied to the coil and the magnetic field generated by the generator interact with each other in a non-resonant condition, wherein while the first driving portion oscillates the mirror portion around the first axis, the second driving portion oscillates the movable portion around the second axis, so that the minor portion reflects a beam of light incident to the mirror portion such that the two-dimensional optical scanner performs a two-dimensional scanning.
