    摘要: A holographic ROM system of the present invention includes a holographic disk for storing information in a form of hologram; a pick-up module for optically reading the information stored in the holographic disk and producing an electrical signal in response to what has been read; and a control unit. The pick-up module has at least two light sources which are controlled by the control unit and a temperature measuring device for measuring an operating temperature of said at least two light sources, and the temperature measuring device transmits a temperature signal indicating the operating temperature to the control unit.

    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.
