Abstract
A multiple degree of freedom actuator can have at least one first MEMS actuator configured to move a platform in translation and at least one second MEMS actuator configured to move the platform in a different direction, e.g., tangentially. The first MEMS actuator(s) can facilitate autofocus and/or zoom, for example. The second MEMS actuator(s) can facilitate optical image stabilization (OIS), for example.
Claims27
A device comprising:
- at least one first MEMS actuator configured to move a platform in translation along a first axis;
- and
- at least one second MEMS actuator configured to move the platform in a direction that is generally perpendicular to the first axis.
A MEMS actuator assembly comprising a plurality of nested actuators configured to focus a camera and to provide optical image stabilization for the camera.
A method for operating a camera, the method comprising:
- moving a platform in translation with at least one first MEMS actuator;
- and
- moving the platform tangentially with at least one second MEMS actuator.
A multiple degree of freedom actuator comprising:
- a fixed frame;
- a platform that is movable with respect to the fixed frame;
- three independently movable MEMS actuators interconnecting the fixed frame and the platform;
- and
- wherein the three MEMS actuators are configured to cooperate to move the platform in three degrees of freedom.
A method comprising:
- providing a platform that is movable with respect to a fixed frame;
- and
- moving the platform in three degrees of freedom using three independently movable MEMS actuators.
