Abstract
An optical module includes a mirror unit including a mirror holder and a mirror on the mirror holder, the mirror holding including a first plate; a center guide supporting the mirror unit; and an actuator configured to rotate the mirror unit about a rotation axis. The actuator includes a first actuator at the first plate and second and third actuators at second and third plates, respectively, and spaced from each other in a direction parallel to the rotation axis, and the first actuator is configured to be acted upon by the second and third actuators to rotate the mirror unit about the rotation axis.
Claims20
An optical module for vibrating a light beam, the optical module comprising:
- a mirror unit comprising a mirror holder and a mirror on the mirror holder, the mirror holder comprising a first plate extending from a side of the mirror holder;
- a center guide supporting the mirror unit, a rotation axis of the mirror unit extending through a center of the center guide;
- and
- an actuator configured to rotate the mirror unit about the rotation axis, the actuator comprising:
- a first actuator at the first plate;
- a second plate and a third plate, the second and third plates being spaced from the first plate;
- and
- a second actuator and a third actuator at the second and third plates, respectively,
- wherein the first actuator is movable relative to the second and third actuators,
- wherein the first actuator is configured to be acted upon by the second actuator and the third actuator to rotate the mirror unit about the rotation axis.
An optical module for vibrating a light beam, the optical module comprising:
- a mirror unit comprising a mirror holder configured to receive a mirror thereon and a plurality of first actuators, the first actuators comprising permanent magnets;
- and
- a second actuator at opposite ends of the mirror unit, comprising a coil-type electromagnet, and configured to rotate the mirror unit about a rotation axis, the coil-type electromagnet comprising an iron pin and a coil wound around the iron pin,
- wherein the first actuators are configured to move relative to the second actuator, and
- wherein the first actuators are configured to be acted upon by the second actuator to rotate the mirror unit about the rotation axis.
