Holographic apparatus having an actuated mirror and corresponding method

摘要

The apparatus has an actuated mirror unit (500) that includes a fixed and a movable body each comprising a piezo-actuator respectively. A rotatable body is mounted on a mirror and is rotatably installed at the movable body. Two prominences (533, 543) are installed at the movable and rotatable body each in contact with the actuators respectively. The two actuators are controllable to be expanded or contracted. An independent claim is also included for a holographic method.
