ACTUATOR AND HOLOGRAPHY DEVICE USING SAME

摘要

[Object] To provide a two-axis actuator having an excellent responsiveness by efficiently using a driving force generated by a magnetic driving unit and a holography apparatus including the two-axis actuator. [Solving Means] When a third axis (a Z-axis passing through a support center point O) that is perpendicular to a first imaginary axis P1-P2 and a second imaginary axis Q-Q that are perpendicular to each other is defined as a reference axis, a magnetic driving mechanism includes a first magnetic driving unit that provides a movable shaft 22b supporting a control target with a driving force to rotate the movable shaft 22b about the first imaginary axis or an axis parallel to the first imaginary axis and a second magnetic driving unit that provides the movable shaft 22b with a driving force to rotate the movable shaft 22b about the second imaginary axis or an axis parallel to the second imaginary axis.
