Holographic apparatus and method adopting actuated mirror

摘要

A holographic apparatus including an actuated mirror includes a fixed body having a first piezo-actuator protrudingly installed thereat; a movable body rectilinearly movable and having a second piezo-actuator protrudingly installed thereat; a rotatable body mounting thereon a mirror and rotatably installed at the movable body; and springs for connecting the fixed body and the movable body and connecting the movable body and the rotatable body to enable a rotational movement of the rotatable body and a rectilinear movement of the movable body. A first prominence is installed at the movable body and in contact with a first piezo-actuator and a second prominence is installed at the rotatable body and in contact with a second piezo-actuator. Moreover, the first and the second piezo-actuators are controllable to be expanded or contracted.
